KR> Dean Cooper's KR2S

[brian.kraut at eamanufacturing.com]

Dean sold the KR probably 8 or 9 years or so ago when he moved to
Armenia for work.  Last I saw of it somebody posted a link to it being
for sale on Craigslist in Tulsa.  Looks like that was February 2015. 
Still in sent box because I forwarded the link to Dean.  Link no longer
works so not sure what happened to it after that.

As far as Dean, he moved to Tulsa, Armenia, then Egypt, and is now
living in Ohio.  He got remarried to a beautiful woman from Armenia and
they have two new young kids now.  I was at his wedding and talk to him
and see him occasionally when he comes back to Jacksonville.

As Paul said Dan, Micro Mesh does a good job.  The question I have is
how deep is the nick?  If it is not very deep you just sand it out with
wet sandpaper then use the MicroMesh in progressively finer grades until
it is polished.  I have a MicroMesh set you can borrow if you need it.

KR> wing tank building material - vinyl ester

[brian.kraut at eamanufacturing.com]

Good warning, but I recommend not going near MEKP catalyst without
goggles, not just safety glasses.  I had a small bottle of catalyst in
my hot garage for a few years and the normally soft plastic squeeze
bottle got hard and brittle (not sure if from the heat, chemical
reaction with catalyst, or a combination) and it shattered like glass
when I squeezed it and sprayed me with a very small droplet getting in
one eye. Fortunately I was 10' from a sink and I knew of the dangers of
MEKP so I was spraying my eyes with water within seconds and got right
to an eye doctor and only had a small chemical burn on my eye.  A bit
more catalyst or another few seconds and I would not still be flying.

KR> Speed Brake/Split Flap

[brian.kraut at eamanufacturing.com]

I fly a Mustang 2 with the big flap that goes under the belly and it is
very effective.  Like the KR, the M2 has stub wings that are not very
long so the flap under the belly adds a lot of flap area.  Basically
what you get are a split flap under the fuselage and conventional flaps
outboard the fuselage.

My first KR did not have a flap or a belly board and it did float a lot
on landings, but I got used to it.  Never flew one with flaps or a belly
board.  On the second KR I was building I extended the stub wings and I
was going to have flaps.  They were going to be hinged off the rear spar
instead of the much smaller plans built design that only gave a chord
about 8-10" IIRC.  The reason they had such a small chord is because
they would drag on the ground with the short retractable gear.

KR> Airworthiness Certificate cancelled or surrendered

[brian.kraut at eamanufacturing.com]

The FAA can reissue an airworthiness certificate.  The place you get
into trouble is if you can't get a signed FAA 8050-2 bill of sale for
the plane.  Some people cancel the registration and won't give the bill
of sale because they don't want the liability and they sell the plane as
parts.  If that happens you can only register it as Experimental
Exibition and Racing which  has a lot of limitations.  To re-register it
as experimental amateur built you have to have the signed 8050 to prove
that it was amateur built.

Of course there are people that take the N number off of a flying plane
that they could not get the 8050 for and they dummy up records showing
it as an unfinished and never registered or flying project that they
bought.  That of course comes with the risk of getting caught and lots
of bad things happening if you do so I would not recommend it.

I recently saw a KR for sale that was "almost ready to fly". After 
looking at it I looked up the tail number and the plane has been 
"deregistered", as well as the Airworthiness Certificate. I've always 
thought that a deregistered aircraft was "dead in the water" but 
according to something I found on the web, there is apparently a path 
back IF the Airworthiness Certificate hasn't been "surrendered". I 
needed clarification on this, and others may need it also. I'm too lazy 
to look up the official regulation on this, but I'm sure it's not too 
hard to find. From a thread on Vans Aircraft:

"Has the original airworthiness been surrendered? If so, the aircraft is

"dead in the water".
Once the airworthiness certificate for an experimental amateur-built 
aircraft has been surrendered, there is no path back.
If the airworthiness is still valid, then no problem. It can be put back

into service by going through a new phase I test program.
No one but the original builder is eligible for the repairman
certificate."

Just FYI...

KR> KR 2 Aerobatics?

[brian.kraut at eamanufacturing.com]

I could be wrong, but by the question you are asking I suspect that you
are not experienced with aerobatics.  The KR certainly has the agility
to perform light aerobatics and it also has the strength to perform
light aerobatics if they are done correctly.

What it lacks are some of the characteristics that would make it a good
plane for someone inexperienced to safely learn aerobatics.  It will
take enough G loading to do most maneuvers, but is not so strong that
you can badly botch a maneuver and not overload it nor is it so strong
that you can do aerobatics with two people and have a comfortable
margin.  The KR is a very low drag airplane so do something incorrectly
and get into a situation with the nose pointed down and you will build
speed very quickly.  Get slow at the top of a loop and stall it and
things get interesting fast.

You are not that far from me so if you are ever in the Northeast corner
of FL give me a shout.

KR> Micro_over_"Smooth_Prime"?

[brian.kraut at eamanufacturing.com]

On my KR I had some pin holes after the Smooth Prime.  I used automotive
icing filler to fill them and it worked great.  It comes in a tube and
can be spread on small holes with a finger, dries fast, and sands
easily.

Something I found with the smooth prime is that it can get little air
bubbles in it.  When you sand the bubbles break and can leave pin holes.
 Use compressed air to blow the dust off and out of the holes so you can
find them after you sand.

KR> Tire pressure and Slime

[brian.kraut at eamanufacturing.com]

Nitrogen is supposed to be better to not slow leak because the molecules
are bigger than regular air.  I always took that with a grain of salt
thinking how much of a difference can it make.

A few months ago I helped a neighbor rebuild the nose strut on his 172. 
He wanted to fill it with nitrogen instead of regular air, but our
friends nitrogen bottle was empty.  I have a CO2 bottle with a regulator
for portable use of air tools and figured that would be as dry as the
nitrogen and just as good.  We filled the strut and the next day it was
empty.  Did it again and same results.  Googled and found that CO2 has
molecules smaller than regular air so we filled it with air and it has
been good since.

So, how much slower would nitrogen leak than air, no idea, but worth a
try.  Airline tires are filled with nitrogen for less leakage, more
convenient on the line to roll out a nitrogen bottle than a compressor
that can go to a few hundred PSI, and less expansion at high
temperatures.

KR> Fuel gauges- senders

[brian.kraut at eamanufacturing.com]

I am not sure if it would be linear or not.  Not sure if the pressure
under so many inches of fuel is the same with a constant area cylinder
or one that gets bigger or smaller as it goes up.  Been too long since I
took physics.

They do sell the sender with or without the fuel computer.  The computer
is used to calibrate the sender at different fuel levels.  I was going
to get it without the computer since my EFIS has calibration built in
for non-linear senders.  You can enter 10 (if I recall correctly) levels
and the system then interpolates between them to give you an accurate
reading over the whole span even without a linear sender.

My plan was to install the sender in a T installed right at the outlet
of the tank which is how the other guy with the Mustang did it.  That is
much easier to do than my other option of installing a capacitative
probe in the tank.  I spoke to Belite and they said a T right in the
fuel outlet is fine.

Subject: Re: KR> Fuel gauges- senders
From: Larry Flesner via KRnet 




One of those sensors mounted in a tee fitting low in the fuselage, 
below or equal to, the bottom of the tank might be a simple and 
accurate fix. I'm thinking "weight" might be linear, even in a 
non-linear tank as long as the sensing intervals are not to short and 
it averages out the reads. I wouldn't want gust loads and G loads in 
turns, etc., to cause the gauge to bounce all over the place.

KR> Fuel gauges- senders

[brian.kraut at eamanufacturing.com]

I have been thinking of getting one of these Belite fuel probes for my
Mustang.  It is basically just a pressure gauge that works based on the
weight of the fuel. 
http://www.beliteaircraftstore.com/uel-probe-system/

I currently have a float sensor in my plane and it is not very
consistent.  I have recalibrated it on my GRT EFIS twice.  I also have a
dead accurate fuel flow system that I rely on, but I don't like pressing
on with my known accurate fuel totalizer telling me all is good and my
known inaccurate fuel level sensor telling me it is not.

One of the other Mustang guys tried the Belite and said it is very
accurate, but it reads higher if you have a pressurized vent tube on the
tank.  I have not decided yet that I want to cut off the bent forward
part of the tube on my fuel vent and add the Belite sensor or not yet. 
I kind of like heaving a positive pressure on the vent line.

KR> Flying on Top

[brian.kraut at eamanufacturing.com]

When I do it I have an EFIS plus backup round airspeed, turn
coordinator, altimeter, and vertical speed, autopilot run off the EFIS,
several GPSs, VOR with ILS, IFR approach plates on my tablet and backup
on my phone, ability to fly ILS or GPS approaches on autopilot off the
EFIS, XM weather, radio and handheld backup also with VOR and ILS and
oxygen and I am on flight following on cross countries.  I also have
over 30 hours IFR training with many hours actual IFR even though I
don't have the rating yet.  And I scan METARS for airports well within
my fuel range to ensure that there are holes to get down and be under
the cloud cover well above ground level before I commit myself to going
over solid cloud cover.  Terrain under me and other weather factors also
are considered.  If all is not looking good I don't go over the top.

To sum it up, I agree that anyone that does VFR over the top needs to be
well prepared and well within their comfort zone and abilities. 
Certainly don't want to give the impression that anyone should just fly
over the top willy nillly and hope for the best at their destination.

KR> Cross country planning and a KR

[brian.kraut at eamanufacturing.com]

I learned to fly long before GPS was invented and I still know how to
plan a flight on paper with a sectional and I would still be comfortable
doing it without GPS, but it has been a few years since I have done it. 
Currently I have Ifly GPS on my tablet so I have legal sectionals and
approach plates if needed and I have it on my phone as a backup.  My
primary GPS I use in the plane is a 496 with XM weather, but I also have
a GPS moving map on my GRT EFIS (that I don't always use because it is
cumbersome to put flight plans orher than a direct to in it, but it is
also my autopilot so doing that more often now) and I have a Garmin
GPS155 that is there as a legal approach certified GPS so I can file IFR
flight plans without having to go VOR to VOR when I finally finish my
IFR rating.  I also have an SL30 with the VOR and ILS input to the EFIS.
 So I have two belts and four pairs of suspenders.

I used to plot plans with paper and sectional when I first started using
GPS.  The reason I stopped doing it is because these days when I fly I
almost never know what altitude and winds aloft I will be flying until I
am in the air.  Sure I could call for weather, and still do, but the
altitude and winds aloft I would plan on the ground are almost never
what I actually use in the air.  Living in Florida there are always lots
of clouds and storms around.  My plane climbs like a bat out of hell and
is efficient up high so I am usually 7-12 thousand feet on top of the
clouds.  Weather reports you get on the ground normally have base height
of layers, but not tops so unless you want to plan a flight at 2,500'
with thunderstorms around that you can't see and go around you don't
know what altitude you will be at until you climb and look around.  I am
also covering a lot of ground quickly so I might climb to 14,000' to get
over clouds or might descent to 6,000 to get under or might divert
around a storm.  Can't plan for any of that on the ground.  And since I
might be making 170 MPG ground speed or might be 230 I usually make my
fuel stop decisions in the air also.

look at the category listings for types they are interested in and will

KR> micro balloons in high build primer?

[brian.kraut at eamanufacturing.com]

I used Smooth Prime put on with a roller when I repainted mine and I
really liked it.  Only comment I have on it is to make sure you vacuum
or blow off the surface after sanding before you put on another coat of
primer or the final paint.  You can get some small bubbles in it and
when you sand off the top of the bubbles you wind up with pin holes. 
Not a lot of them and no problem to fill them, but if you don't blow off
or vacuum the surface they fill with the sanding dust and you don't know
they are there until you see them after spraying your final coat.  I
filled the pin holes with icing and a quick sand in no time at all.

I used Smooth Prime ( 
http://www.aircraftspruce.com/catalog/cspages/smoothprime.php?clickkey=30869

) 15 years ago when finishing my KR. It seems a bit expensive now 
but it wasn't cheap back then either. I don't recall how much it 
took but certainly not the three gallon it suggest in the ad, maybe a 
gallon and a quart. It is water based and I put it on a bit at a 
time with a 4 inch foam roll as I finished different areas of the 
plane. I covered it with cheap auto paint ($40 a gallon in early 
2000) and it still looks like the day it was painted. Paint was 
never buffed out and I still have two spots on the left wing that 
have been in primer since 2004 where I cut in to the wing to fix a 
fuel leak. Nobody every notices the primer spots and I've just never 
bothered to paint them.

The trick to eliminating fill is to get the foam right, get a good 
glass lay up, then cover with "deck cloth" for minimum fill. If you 
look "real close" you can see one of the primer spots in the photo.

KR> Todd's Canopies

[brian.kraut at eamanufacturing.com]

Sorry to pass this information on.  I know a lot of you got your
canopies from Todd and I had always heard good things about him.  I only
spoke to Todd once several years ago, but he was very helpful.

KR> [CorvAircraft] Prop

[brian.kraut at eamanufacturing.com]

I spoke to Ed Sterba about that a few years ago and he told me that low
drag planes like the KR and the Midget Mustang can go faster than the
theoretical pitch will allow.

I am not a prop expert, but if I had to take a wild guess as to a theory
which may or may not be correct I would look at this.  Prop pitch is not
as simple as the angle of incidence of the airfoil.  A propeller is not
a screw that exactly moves so many inches forward for each revolution. 
For one thing, it is an airfoil, not just a flat surface.  It is not
"screwing" its way through the air, it is creating lift 90 degrees to
the axis it is spinning.  And if it were a screw you need to remember
that the root is a much higher pitch than the tips so the prop would
"screw" its way further at the root than the tip.  The effective
distance it would "screw" forward is somewhere between the pitch of the
root and the pitch of the tip and depends on the drag of the plane.

Or to sum it all up, it is PFM and black magic and the formula, as Mark
says, does not always fit, it is a rule of thumb to get an approximation
only.

That equation has never worked for me either. If it makes anybody feel 
any better, Joe Horton reminded me today that he can reproduce 180 mph 
TAS on a regular basis, and his ASI system is well calibrated. He also 
has a nosewheel out front. Temperature and altitude are factors, and of 
course RPM and weight of the plane.

I flew the KR2 (old wing) with a 54x50 prop today at WOT at 168 mph TAS 
at about 2500 ft, so I'm getting over 100% efficiency. Bottom line is 
this equation doesn't fit KRs. Properly built, they are simply more 
efficient than most airplanes out there, especially at the time that 
equation was probably hatched...I'm guessing the early 1940's.

KR> Ifly 720

[brian.kraut at eamanufacturing.com]

I have been using the Ifly GPS app on my tablet and phone for over a
year and love it.  I recently got a new project (Murphy Rebel) that came
with an Ifly 720.  I powered it up over the weekend and noticed that it
took probably a minute or so to boot up and operation seems to not be
very fast on it.  I kind of expected that on their dedicated hardware
that it would zip right along or at least run as good as it does on my
phone that is also running 100 other processes at the same time.  I also
noticed that the touch screen requires a harder touch than my phone or
tablet (which may be a good thing bouncing around in the cockpit)

Can any of you that run the 720 comment on this?  I am wondering if this
is normal or if mine might have some issues.

Also, did they hide a power button the unit somewhere that I just have
not found yet?

KR> General Aviation ADS-B Rebate Program

[brian.kraut at eamanufacturing.com]

Can't really say that I am overly happy that the FAA is giving away ten
million dollars of our tax money with rebates.

As far as equipping your plane now, if you feel it is worth the money to
you go ahead, but for the rebate you need TSOd equipment.  Have not been
looking at prices myself, but just might be more than $500 less if you
got a non-TSOd unit which is not eligible for the rebate.

Personally, I am going to wait at least a few years.  I deal with
electronics for large commercial ships for a living and I have been
through very many mandatory new equipment requirements (several dozen at
least) and every time it is the same story.  Calls of panic from the
regulators and the equipment manufacturers that equipment prices may go
up and ship owners may not be able to get equipment or installation in
time if they wait till close to the deadline.  This is followed by
newer, better, and less expensive equipment being introduced by lots of
manufacturers, then followed by major price cuts as all the
manufacturers try to get as much of the market share as possible.  Would
not surprise me at all if there are $300 solutions readily available
before the deadline.

KR> Ethanol

[brian.kraut at eamanufacturing.com]

Keep in mind that the original post was regarding pure ethanol which is
a different animal than automotive gas with 10% ethanol that you get at
your local gas station.  The concerns with using ethanol containing gas
and the reasons the FAA does not allow its use in certified planes with
auto fuel STCs are still valid.

I had an old Cadillac with a computer display that would read out my
real-time fuel consumption. I imagine most cars have such things these
days, althoiugh the Oldsmobile that I replaced my beloved Cadillac with
doesn't. Whenever I would drive cross country and got into the mid-west
where ethanol is sold, my fuel mileage would always go down. 

I'm impressed by the statement "The fastest cars in the country use it."
so obviously I'm suffering form a misconception. I inherently disliked
it because it decreased my fuel mileage and because government welfare
to
all the farmers who grow corn for ethanol annoyes me too. Plus, I've
never trusted it in my KR. If I do ever use auto fuel in the KR
(GP-2180) I always use Chevron Supreme, which is what I always use in my
other vehicles. Calling Chevron headquarters in San Francisco several
years ago, they told me Supreme has 7% ethanol in it. It may be more
now, or less, but thinking I could avoid ethanol by buying top grade
gasoline was not correct. I think it's all got ethanol in it, except for
boutique racing shops that sell ethanol-free gas for racing. Why would
racing shops sell ethanol-free gas for racing if "the fastest cars in
the
country use it." I'm not arguing here since I'm not very smart, but just
relating my experiences. 

Steve Bennett said he always ran my engine on ethanol-free gas - which
he
could get in Omaha. Here in San Diego it's only available from
specialized racing shops. From Steve's comments on operation of my
engine, I've tried to keep ethanol out of the tanks but I have
occasionally put some Chevron Supreme in. It's always mixed with
whatever 100LL is already in the tank. In my aux tank in the wing, made
from vinyl ester, I've been religious about never putting anything but
100LL in it. I've heard too many stories about car gas wreaking havoc to
tanks and fuel components for me to use it more than very occasionally. 
Just my experience. I'm still learning new things . . .hope we all are.

KR> Oil additives

I had a friend that worked for the city doing auto maintenance.  Did
tons of engine rebuilds on the police cars and he swore by Rotella.  The
fact that it is sold in gallon jugs so they are easy to fill back up to
get rid of the old oil is nice too.

Scott Casler of Hummel Engines recommends Rotella for any VW 
application, for the zinc content. That goes for cars too. As I 
understand it, the metallurgy of auto engines changed in the 80s to be 
compatible with the mandated lower zinc levels in oil. So I suppose that

means if you didn't give up your Bricklin to Cash For Clunkers, it would

be wise to run Rotella.

Yep, my iEFIS failed to come to life when I turned it on to return home 
from a flight to my father's farm a few weeks ago, despite having power 
and backup power as well. Consider being 250 miles from home, and 
suddenly you have no engine info, such as RPM, oil pressure, oil temp, 
CHTs, EGTs, barometric altitude or airspeed, transponder encoder, or 
fuel consumption or level. I still had the iFLY 720 GPS and Foreflight 
on the iPhone (if I needed it), but flying back home with no engine info

was a sobering thought, not to mention issues with several FARs, I'm 
sure. A few days later it was just fine, so now I have an intermittent 
problem that's waiting to bite me again.

And yes, I too have designed a new panel, using an iPad, iFLY 720, GRT

indicator. I don't like having all my eggs in one flaky basket...

KR> wing attach fittings.

[brian.kraut at eamanufacturing.com]

Someone correct me if I am wrong on this, it has been a little while and
my memory is not 100% clear.

The main spar fittings are exactly the same for both the 2 and the 2S. 
On the aft spar of the 2 the fittings should all the same, but on the 2S
the spar cants forward a few degrees some of the aft fittings are a bit
longer with a slight difference in spacing from the attach bolt hole to
the holes that go through the spar.  They also have a slight bend to
them.  So basically if you bought a set of 2S fittings to use on a 2 or
vice versa you would need to remake either four or eight of the aft
fittings, can't remember if there are four oddballs or eight.

KR> Brian's semi annual cleaning out the hanger sale

[brian.kraut at eamanufacturing.com]

I have just found and listed my set of wing attach fittings on Ebay. 
These are original Rand factory made and plated fittings for a 2S.  I
have also listed a very nice Terra TN200D nav receiver and indicator. 
This is a great compact nav receiver with built in glideslope receiver. 
It is a low cost way to get VOR, ILS, and glideslope in a KR.  Not many
other solutions are as small and light weight, not to mention cost
effective.  The nav receiver is brand new and the indicator is tested
and yellow tagged.  I have also listed a very nice fuel flow computer
and sender that I was using in my Mustang 2 until I put in a new engine
monitor and EFIS.  There is also a brand new 12V linear actuator that
may be suitable as a belly board actuator, but you ill need to look at
the specs and determine if it has the correct thrust and travel.

I am listing other parts tomorrow including a bunch of gauges, master
cylinders, some rudder pedals, and other stuff so keep looking.

KR> Manifold vacuum

[brian.kraut at eamanufacturing.com]

And the fact that you can put in pitot and static and use it as a
primary display instead of a portable backup means you can forgo the
airspeed, vertical speed, and altimeter if you want.  Now you have
something that saves you a bunch of weight and costs not much more than
the instruments it replaces.  if you are going to use it as a primary
instrument though you should consider upgrading to the Sport EFIS with
the bigger screen.

I didn't even look at GRT when looking for a portable attitude
instrument. I've been thinking of GRT as a supplier or large panel mount
screens but I'm really out of date. The GRT mini is a far superior
instrument to the Dynon and many ways, not least the fact that it "
Incorporates a full AHRS solution that does not require GPS or air data
to provide attitude data." 

That alone makes it a serious instrument, as opposed to a being a fair
weather toy like the Dynon, but I'm seeing it also incorporates a
database (worldwide if wanted), moving map, and tons of other features,
some optional, some standard. The base unit is about the same price as
the Dynon . . . so only an idiot like me would have bought the Dynon
when I could have bought this for about the same money.

At least the Dynon was easy to sell . . . and it did work really well
for
what I bought it for. It wasn't a keeper though.

I'm getting ready to upgrade to a more sophisticated navigator for the
KR. My Anywheremap ATC is really getting long in the tooth, plus I'm
looking for a portable that can load approaches and communicate with the
new TruTrak ECO autopilot I intend to buy. The GRT mini may do that -
there's a lot to read regarding this unit with all of its permutations
and options. Up 'till now, the only portable GPS I've found that loads
full approaches plus SIDS and STARS are the ones from Aviationsafety. 
They used to be known as "Flight Cheetah" . . . perhaps they still are. 
I've got a lot more reading to do with their products as well. 

Folding ADS-B in/out into the navigator/autopilot system I'm envisioning
is part of this project I'm embarking on. Doing all of this at
relatively low cost and in a way that fits easily within my small
cockpit
environment is an interesting project - one that appears to be quite
doable based upon the limited research I've done so far. I should have
an amazing all weather travelling machine when I'm finished. Yes, a
pressurized turbine-powered Lancair would be a more suitable airframe
for
what I have in mind, but I guess I'll just have to make do with what
I've
got. It's plenty good enough.

"Gyros are heavy and require a vacuum source with a lot of associated
heavy plumbing. Mike Stirewalt has his Dynon D2 for sale for a very
reasonable price." 

I did have it for sale . . . but within minutes of listing it on
Vansairforce I had two buyers. I sold it to the one whose email came in
first. 

I can't recommend the Dynon D2, although it worked exceedingly well on
the recent ferry flight for which I bought it. The attitude information
it displays is dependent upon receiving a GPS signal. It has it's own
internal GPS and gyros it's true but for some inexplicable reason if it
loses a GPS signal - it happens - you lose your horizon. 

For a low-cost attitude instrument I highly recommend the TruTrak ADI. 
Used ones sometime show up on eBay in the $500-600 range. They used to
make the 3 1/8" ADI which is the one I have in the KR. Currently their
ADI that looks like mine is a 2+ inch instrument, which is fine. I just
prefer the larger one. They do make a couple newer instruments which do
the same thing as their ADI but look a little different. The name Gemini
comes to mind, but check out their website. These instruments by
TruTrak, the ADI, Gemini and I think a couple others they make are
self-contained attitude instruments. They do connect to a GPS puck but
that is strictly for ground track (heading) information. 

The D2 is very smooth and usable. I liked it. However, just imagine
being totally dependent on it when in IFR conditions - cloud or on a
very
dark night without any outside reference. I don't like the idea at all
of its dependency upon a GPS signal. 

Thanks Jeff.

The theory is good. But it takes too much power to spin a vacuum pump to
the rpm required to operate in the proper range. The weight of the
electric motor required to produce enough power to spin a pump, and the
amps required, is not worth it. There are electric vacuum pumps on the
market for certified aircraft. They are used as backup systems to get
you on the ground. Heavy, high amps, expensive. The only reliable ways
to power instruments is venturi, dry or wet vacuum pump, or electrical
instruments. I'm an A&P, ex corporate, cargo, charter pilot. And I do
think outside the box most of the time. Have had my KR2 going for 20
years.

I encountered an interesting 'option' on a car a bought that I had
"doubts"
about - electric power steering. The pump is driven by an electric motor
powered by the electrical system (battery) and has always worked,
although
the car is relatively new. Why not tie the vacuum pump into the
electrical
system? You may be able to tie in a low draw motor and rotary pump to
drive
the vacuum gages/instruments - most that I've seen don't need a lot of
vacuum, so why not?

Manifold vacuum isn't something I'd depend on.  As engine load goes up,
manifold vacuum goes down.  I'd worry about instruments getting good
vacuum
on climbout.  If the engine cuts out, your manifold vacuum will drop as
well
(even if the prop windmills).  Using exhaust to produce vacuum is
interesting too, I bet it would work, but I doubt you'd get good vacuum
with
the engine windmilling.

I suppose i'm making the argument for a vacuum horn, or an engine driven
vacuum pump, and am assuming the engine will windmill.

KR> Wing Attach Fitting questions

[brian.kraut at eamanufacturing.com]

I certainly would not weld up a hole in a wing attach fitting.  There is
no telling what would have in the way of small voids and/or cracks in
the weld, soft or hard and brittle spots from contamination, etc.  If it
was welded you would need to remove any plating, use a 4130 welding rod,
put on some extra material, then machine it down flat again, re heat
treat it, and if I was flying it all would be done by a professional
aerospace welder and it would get professionally inspected for cracks by
X ray, eddy current, magnaflux, or whatever the correct method is. 
Admittedly, I may be going too far, but I certainly would not weld it
and put my ass in the plane.

I remade a set of wing attach fittings for a Starduster 2 once.  The
holes to attach it to the spars were hand drilled so they were not
perfectly spaced.  I wanted the new holes to perfectly match the holes
drilled in the wood spar so what I did was clamp the new undrilled
fitting on my milling machine, put the old fitting on top of it and
eyeball align the first hole and drill, put a bolt through both fittings
to hole them together aligned, then one more hole at a time I found the
center of each with a dial indicator and indicated and drilled one hole
at a time.  I think it took three or four hours to do eight fittings,
but the result was new fittings that perfectly matched the holes drilled
in the spars.  Any machine shop should be able to do this for you if you
have fittings that are not machine drilled to the exact spacing.

Epoxied in dowels may also be acceptable, but been a long time since I
have read the wood repair section of the 43.13.

Ok...

Since some folks here have a much better understanding of the 'design'
behind the WAFs than I do...

I'm not an engineer, and I don't want to die... So further experience
would
probably help

Some questions:

1) What is the key force or mechanisim providing strength to the WAF
joint?
Is it the clamping pressure imparted by the bolts? The shaft of the bolt
itself?

2) Is there a preferred method to 'adjust' a set of wing fittings that
were drilled wrong? Would welding up the hole & re-drilling work?
Bushings?
Just make a new set?

Any other info would be useful.

I'm trying to mate wings from another KR, that I bought, to mine...

KR> Piston rings

[brian.kraut at eamanufacturing.com]

I had an O-290D in my Pacer and had a hard time finding parts when I
needed to do a top overhaul.  Pistons were pretty scarce.  I did find
what I needed from Gibson.  http://www.gibsonaviationok.com/

The O-290D2 is easier to find parts for and for future reference if
anyone is looking at planes with the 290 try to get a D2 instead of the
D.  Parts are easier to find, I think a bit more HP, and it has
hydraulic lifters unlike the D.

I called a Lycoming rep at the time when I was trying to find pistons
and he told me that the reason the 290D parts were hard to find was
because it used most of the same parts as the 290G ground power unit and
a lot of the 290D engines were now in experimentals and using the 290G
parts, so much so, that people were not buying many 290D parts anymore
hence they stopped making them.

KR> X Carv parts maker

[brian.kraut at eamanufacturing.com]

Having a CNC router, a Bridgeport milling machine converted to CNC, and
a 40W CNC laser I hardly ever make a part without using one of them
anymore and they are tremendously useful, but I design and build things
as a big part of my living so my tools all pay for themselves.  If it
was just for building a KR I would say you could probably build it
faster, and certainly cheaper without a CNC, but most of us building
planes are tinkerers and can find plenty of other uses for it also.

KR> Aileron spar

[brian.kraut at eamanufacturing.com]

The thought of wood screws holding your ailerons on in 1/4" wood, or
even thicker for that matter, would scare me.  When I had my first KR I
had to replace my aileron hinges for some reason I no longer remember
and I did all new screw holes and nut plates.  It was fairly easy to add
them to an already built wing.  I just cut holes in the glass on the
tops of the wings about an inch and a half by an inch to epoxy the nut
plates to the aft of the spar.  When I was done and made sure my threads
were all good I stuffed little blocks of foam in the access holes I cut,
sanded, and glassed on some small patches with two layers of glass to
cover the holes.  With a minimum amount of filler and sanding you could
not tell that I cut the holes.

The point I was trying to make was. What's wrong with using wood screws
on the aileron hinges? Just curious. I think it has been proven that
they work on belly boards going 130 mph and they don't fall off. One
think I can think of. The plans call for Nut plates and getting it past
the DAR might be an issue. Being the ailerons are a primary flight
control and the speed brake is not. Just a thought.

I would not use screws for attachment.  I used a 
piece of 1/4" foam to construct my belly board 
with glass wrap.  I drilled multiple 1/8" holes 
in the hinge on the board side and used 
epoxy/flox and one overlay of glass to secure.  I 
used a piece of 1/4" X 1 1/2" piece of pine from 
the lumber yard on the floor behind the rear spar 
and used five 3/16" bolts with "wood washers" to 
attach to the floor of the fuselage.  500 hours

We don't really *need* dual plugs in such low volume firing chambers. 
Dual plugs are an adequate solution for jugs with massive volumes. For
smaller engines, they just give another place for the head to crack and
serve no useful purpose. Engines are so reliable these days, when was
the last time you heard of a plug breaking down in a normally maintained
engine? So if you have the choice, one plug per cylinder in normal
sized jugs is just fine.

cool project but the performance specs dont seem very efficient. high
gas consumption, long takeoff roll fast pattern speeds, and a gas hog!
plane seems a bit heavy too. 
full disclosure, I am a pilot but not a builder (yet). its an impressive
project from experimentation standpoint with a strong coolness factor
too.

Speaking of T88, does anyone know of a good source for the type of
squeeze bottles that they put T-88 in?  I always kept my laminating
epoxy in T-88 squeeze bottles since it is easy to dispense what you
need, but my last set of bottles are long gone.  I have tried some
grocery store ketchup and mustard bottles and bought some online from
somewhere once, but all of them were not heavy duty enough.  If you
squeezed hard the lids would pop off.  The ones they use for T-88 have
good heavy duty lids that stay on.

There's a time and place for that. And if there's no other option, then
that's the one to choose. 

But you are assuming a "problem." I'm presuming to avoid any problem. I
don't like problems, especially in such a time and place as this
hypothetical ramp in the middle of Wyoming in winter. I'm taking
measures, with my battery installation, to make sure as best I can that
there will be nothing to interfere with me using lots of electrics to
land, taxi to the fuel dowser, fill up, get back in the plane, start the
engine and continue my journey. In such a circumstance, if the battery
is dead because it's overdrawn, then I have a problem. I don't want
that. Anything I can do to help prevent such a problem is something I
feel obligated to do. 

Now, I've admitted my ignorance of lithium battery technology, at least
to Larry. I'm admitting that it's possible there is a lithium battery
that will match the specs of this M44 battery, same Ah, same reserve
capacity, perhaps less weight but weight isn't important to me - I'm
just
wondering if a battery of this size (garden tractor size) exists in the
lithium world that would do as well as this AGM I've got and am so
excited (some would say overly) to find. I guessing the military has
some specialized lithium batteries with amazing specs and they may very
well have something that's equal or even better than this M44 I've now
got. I will be keeping an eye out as time goes by but meanwhile, if
Brian or anyone knowledgable about sophisticated lithium batteries would
like to point me in a particular direction I would appreciate it. For
future reference, I'd like to know what is going on in the lithium world
of high performance batteries. 

Dj said,

That's probably true. It can't hurt though. It's probably highly
unnecessary unless you're stationed in Antarctica or flying in the far
north.

KR> Batteries

[brian.kraut at eamanufacturing.com]

When I was working on my 2S which was to have a Corvair with electronic
ignition and fuel only in the wings and needing a fuel pump I thought of
the backup battery situation and I was considering instead of a big
battery for starting and a small one as a backup using two smallish 7AH
or so batteries with a paralleling solenoid that would be used only for
starting.  I figured I would diode isolate both alternator feeds to
charge the batteries and have one buss for primary ignition and one fuel
pump and the second for secondary ignition and the other fuel pump.  The
buss for electronics, lights, etc. would have a switch so it could run
off either battery.

Not sure if this would be the best way to do it or not, but it is an
alternative to think about vs. the big battery and small backup battery.

My Mustang is using the big/small battery method because it makes sense
to me on this particular plane with the backup only needed for avionics,
not for critical things like ignition and fuel pump.

The Odyssey (PC680) is probably the very best choice in batteries for 
the KR. That's the battery I use in my 
KR. https://dl.dropboxusercontent.com/u/32133949/IMG_8083.jpg I 
question the reserve capacity of the LI-on and other types of Lithium 
batteries to carry the load if the alternator goes south. I will 
trust my little 4 AMP hour backup battery (seen just above the 
Odyssey in the photo) to be ready and able to keep my fuel pump(s) 
and other optional equipment running if and when I loose my 
electrical system. To me it's a known quantity. It happened once, 
the engine never sputtered, and I landed safely. I keep it charged 
while flying and can keep it charged with alternator output if I need 
to bring it on line.

KR> Battery

I have a PC680 battery in my Mustang 2 and it is great and small.  It is
pretty much the standard RV battery.  They make smaller versions also. 
They are heavy though (not as heavy as most lead acid, but heavy none
the less).


If I was buying a new battery today I would get a LiFePo4 (Lithium Iron
Phosphate).  These are almost as light and high capacity as Lithium ion
and Lithium Polymer batteries, but they are much safer.  Li and LIPo
tend to explode or catch fire when abused so I do not recommend them,
but LiFePo4 are safe.


There are many Lithium iron phosphate batteries you can buy today, but
they need special balance chargers and other protection methods.  The
only ones I know of that have all of that already built into the battery
are from EarthEx. 
http://earthxmotorsports.com/product-category/experimental-aircraft



I have one of the small ETX12B batteries that I bought for my avionics
backup.  It is 1.3 pounds and can back up all I need for IFR for longer
than my engine can run on a tank of fuel.  I will be getting one of
their larger batteries for engine starting when my PC680 dies (which
from experience of others will not be for many years).

Oh, and this discussion reminds me of a funny story.

I work at a big marine show in New Orleans every year and a lot of the
companies that have booths at the show give away pens, coozies, etc,
with their logo on it.  One year Sperry Marine, which is the inventor of
the gyrocompass and they sell marine magnetic compasses and other
navigation equipment, was giving away a small keychain magnetic compass
with their name on it.  Only problem is that the key ring on it was
steel so no matter which way you turned it north was always pointing at
the key ring.

Good idea from their marketing department, but they get a big zero on
the execution. 

KR> Possible replacement for a whiskey compass?

I also almost never look at my compass, but keep in mind that when ATC
tells you to turn to a heading they are referring to a magnetic heading,
not course, which is what you are getting from the GPS.  Here in FL they
are pretty close, flying in Alaska, not so much.

KR> Possible replacement for a whiskey compass?

[brian.kraut at eamanufacturing.com]

The device is a flux gate compass.  I would think that the FAA would
want something that does not require power at all.  That is kind of the
point of having a magnetic compass.  Since it is battery powered you
might be able to get away with it, but I would think carrying an extra
battery and having the means to change it in flight would be required.

As far as a correction card is concerned, yes, you would need one.  The
fluxgate compass is affected by external magnetic materials in the plane
just like a regular magnetic compass is.  Flux gate compasses that are
made for automotive and marine use have calibration procedures that
internally correct the readings, but even very good ones are a few
degrees off in some direction.  I would suspect that this handheld one
would not have compensation built in because it is intended to be hand
held and not fixed mounted where the the external magnetic influences
are always the same.

One other concern I have with it is that the sensor inside it is most
likely orientated so that the face of it is parallel to the ground as it
would be if you were holding it in your hand.  In that orientation you
would not be able to see it in the plane unless you put it in your lap. 
In your phone there are multiple sensors in different orientations so
you can hold it vertical or horizontal.

My day job is in shipboard electronics.  I realize that marine rules and
FAA rules are not the same, but for ships the requirement for a compass
means a magnetic compass.  Even ships with gyrocompasses are required to
have magnetic compasses.  Some classes of ships are also required to
have transmitting magnetic compasses with sensors on them as an
alternate method to give heading data to the radar if the gyro fails.

The device whose ad I originally posted l is battery powered. Am I right
to assume that qualifies as "no external power? "

I was planning to have no conventional instruments, but to replace the
fight instruments wirh a Dynon EFIS, which has a dedicated battery
backup.
(By the time I'm ready for this, they will be available used or NOS).

I also have an old Magellan backpacker's GPS 300 that I was thinking of
using as a backup. It's primitive by today's standards as a GPS, but it
gives your altitude and shows your compass direction whenever you're
moving.

I think when Dan Diehl tested the KR2 unidirectional glass legs that he
manufactured or cut from from Scotchply he found that due to the offset
in
angle forward and outwards that there was a tendency for the legs to
twist
slightly as they flexed on landing. The glass 45 degree wrapping was
intended to reduce that torsional influence. However, I don't know how
significant either the twist or the wrapping to address it proved to be.
Nor
do I have any knowledge of how the Gruman legs would act although
because
they are thicker it is possibly even less of an issue. Scotchply has
since
been taken over by others (Cyply??) and is hideously expensive.

KR> Reaming WAFs

[brian.kraut at eamanufacturing.com]

And that is almost how they are done on the Mustang 2.  Those without
folding wings use a bolt and nut, but when using folding wings you use a
bolt ground to a bullet shaped end instead of threads and just bang it
in the hole.  The wing gap seal has a piece on it that keeps them from
being able to back out.

However, on the KR I do recommend a nut and if you are putting it on
might as well torque it correctly.  Since you have two relatively thin
WAFs that can be bent a bit it is best to have them clamped together so
the bolt is really loaded only in shear as designed.

KR> Tripple Tree

[brian.kraut at eamanufacturing.com]

Just wanted to make sure that everyone knows about the Tripple Tree
Flyin in SC 9/9 till 9/13.  This is a great Flyin that a lot of people
have not heard of.  I think they had something like 800 planes show up
there last year.  It really is a not to be missed event.

KR> fuel line through the spar caps?

[brian.kraut at eamanufacturing.com]

I used 1/4" for my transfer lines and they worked fine.  I think it took
me something like 5 minutes to transfer the whole 5 gallon tank and you
could hear when it was empty.  On mine I only used one pump and had it
after the fuel selector.  I didn't have a return line.  If I transferred
too much fuel too soon before I used enough in the header it would just
dump out the header vent line.

Good Info Brian? my plans were to mount it lower than the wing
cells?. so I?m okay there? Also transferring to main tank but by
1/4? lines?.. then return overflow to one wing cell again via 1/4
? Considering more volume under pump pressure than gravity flow
overflow to wing? I would appreciate any comments on line size.. or am
I being to engineered? jw

KR> fuel line through the spar caps?

[brian.kraut at eamanufacturing.com]

Keep those Facet pumps low.  They don't do good with pulling a prime
uphill which I learned on my aux wing tanks transferring to the header
tank.  I originally had my pump mounted on the back side of the header
tank, but I moved it down low on a doubler on the front of the spar when
I had an issue with it not sucking up a prime.

KR> BRS vs Bean Field

Being a glider pilot I have made several hundred dead stick landings so
I laugh at 27.

I'm new here so why wouldnt I believe the 27 number. Mark could have
been flying a prolific number of hours and for decades. As experimental
builders/operators, the idea is to try new engineering ideas. I have
friends who have run into issues with fueling, cooling, you name it. I
think it's more important to position ones self for successful
unanticipated landings than to hopelessly believe they cant happen.
Considering the great job mark did in his Bean field visit, 26 priors
for practice doesnt seem totally unrealistic! ;)

KR> Blanks/BRS

[brian.kraut at eamanufacturing.com]

LOL.  In that case the BRS would not have helped since I was never high
enough to deploy it.

What it really comes down to is that you can be prepared for a hundred
different situations you can get into, but the thing that gets you might
just be the one you did not prepare for.  Heck, the thing that gets you
just might be because of your preparations such as a passenger pulling
the BRS handle at a most inopportune time like just before clearing the
trees at the approach end of the runway during a normal landing.  

We all need to evaluate the flying we normally do and figure out what
makes sense for us within our budget, weight allowance, and a hundred
other factors.  For some of us a BRS makes a lot of sense.  For others
it does not, but don't make that decision based on just what you read
from some posts from different people flying different planes in
different situations.  Evaluating your own needs and acting accordingly
is what makes you not a weenie.

Two of the most knowledgable netters whose posts are always worth
reading, Langford and Brian Kraut, frequently leave posts which are
blank. I doubt in most cases they even know their posts are coming
through as blanks since how often do these busy people take the time to
go back and read a post to see if it made it through the system okay? 
The phenomenon of blank emails is probably not even noticable to the
poster unless they're using digest mode.

It sure wouldn't contribute to _my_ peace of mind. I would be annoyed
every time I got in the plane and noted I had devoted valuable space to
something fairly bulky that requires repacking and inspection
periodically and costs quite a bit of money to buy and maintain. That
money would, in my case, be a lot better spent on something like an
autopilot or some other luxury. There's also that lurking thought in the
back of my mind that the thing wouldn't work if I ever _did_ try and use
it. Which I wouldn't. Pushing the button would make me feel like a big
weenie.

KR> GP 2180 Valves/LOP

[brian.kraut at eamanufacturing.com]

Not sure on VW, but according to both Lycoming and Continental below 65%
power you can run as rich or lean as you want without danger of hurting
the engine, just need to pay attention to the CHT and make sure they are
in limits (which running LOP actually lowers the CHT).  I have found in
my Mustang 2 with an O-360 that backing the power back from 75% power to
65% power and 50 degrees LOP my cruise speed drops from 191 MPH to about
180, but my fuel burn goes from over 7.5 GPH to about 6.25, not a bad
trade-off.  This is on a carberated engine, not fuel injected with
matched injectors as most people believe you need to have to run LOP. 
My cylinders are generally one about 65 degrees LOP, one maybe 20, and
one maybe 10, but as stated, that is no problem under 65% power.

 If running at 70% power or less whatever our altitude might be,
there's nothing we can do with the mixture that can hurt the engine. 
Unless we run it too rich - which does indeed hurt the engine in a
variety of ways.

Flying down low is not as efficient as flying up high, but sometimes the
trip length doesn't warrant going high. Whether high or low, keep the VW
cool and it'll keep us cool.

KR> Panel work

[brian.kraut at eamanufacturing.com]

I have a laser engraver.  If anyone needs any work done send me an email
to brian at eamanufacturing.com.  I use a thin engraving stock that is only
.020" thick.  It is reverse engraving meaning instead of the normal
black plastic on the front and a white core it is a clear acrylic front
and a black thin layer on the back.  It is engraved from the back then
paint filled so I can do multiple colors of text and the front face is
perfectly smooth.  I do cuts and engraving on the laser so you can have
any shape you want with the switch holes already cut in the plastic.

KR> Measuring vinyl ester resin

[brian.kraut at eamanufacturing.com]

You certainly could find out what the weight of the catalyst is by
volume and then use that, but the amount of catalyst is not that
critical on VE (changes hardening time, not strength that I know of). 
Weighing it will also require it going into another container, going on
a scale, and more handling of it and the less you have to handle the
MEKP the better.

KR> Measuring vinyl ester resin

[brian.kraut at eamanufacturing.com]

I used to use one of these dispensers.
http://www.aircraftspruce.com/catalog/cmpages/dispenser.php?clickkey=419683


They work good.  You can also get a dropper and count the drops.

Be aware that MEKP is extremely dangerous if you get it in your eyes.  I
won't even touch a bottle of it anymore without goggles on, not safety
glasses, goggles that fully seal around my eyes and close to running
water.

Several years ago I had some that had sat in my garage for a long time
in the original plastic bottle it came in.  I thought that the MEKP
solidified because the normally soft plastic dropper bottle was hard. 
Didn't realize that the MEKP was still liquid, but the heat and/or
chemical reaction made the bottle hard and brittle.  I gave it a little
squeeze and the brittle bottle shattered and sprayed in my face. 
Remembering the dire warnings from A&P school about how one drop can
blind you I had my face under the kitchen sink a second later followed
by 15 minutes in the shower with all my clothes on spraying water in my
face followed by a trip with MSDS sheet in hand to an eye doctor.  I was
very lucky that it was a miniscule amount in my eye and I knew how
dangerous it was so I reacted immediately, but still have permanent
damage.
