KR> Tso instruments Or not

[peter]

Stef; Tso'ed instruments are included under the Tso (technical service order) 
for an aircraft type as part of the airframe/engine as tested and certified (in 
1946). They are assumed by the experimental crowd to be "accurate" for our use, 
but are not necessarily different from, or better than, other available 
instruments, (condoms work, why use birthcontrol pills). Tachometers (RPM) for 
instance, are "better" and cheaper if built for trucks because they are not 
designs from 1941 but from 2012, and have improved with new mass-production 
changes... EGT- buy non-tso'ed, Manifold Pressure non-tso, fuel quantity- 
non-tso, Altimeter-tso, airspeed -Tso, veritical speed indicator - glider 
variometer. Generally, go where the market is large for manufacturing 
efficiencies, and where regulation is the least- as in ultralights and gliders 
and trucks. Actually, instruments are dependent on sensors, and they have 
improved by orders of magnitude since the pre-transistor days, and the displays 
are really good. Look for all non-tso, except the altimeter.

Hi kr friends,
Wat is the standard in your country's. And what kind of instrument did you 
install in your kr-2. Tso Or not. Saves a lot of money.
Greats Stef

KR> Tso instruments Or not

[Dan Heath]

No TSO required and I use Dynon.  If I ever could go IFR, then I would have
to install at least one TSO and that would cost a bundle.

KR> Landing speeds

[Joe Nunley]

Dear Colin,

If the weather is good, I fly about 3 to 4 times a week.  I fly with my
"other"plane out of the 1200 foot strip.  I have been testing different
landing techniques in preparation for the completion of my KR2.  I have
found that the technique that you describe, "push the stick forward to pin
the aircraft on the ground, ride the bumps, I can see clearly and you
balance the aircraft on brakes and rudder and slowly have to push more
forward as the speed bleeds off",  is the technique that I believe to be
the most viable option. One reason it appears viable is that  I spend less
time floating and more time slowing down.  A given touchdown speed gives a
fairly consistent landing distance taking wind and weight as variables. I
can duplicate landings consistently and so far safely.  I have found that,
for me, I use 70 MPH instead of your 80 MPH, 70 MPH is still
a controllable speed and I only have 1200 feet.  Everything else seems
about the same.  Thank you for sharing.

I greatly appreciate everyone's input and value their opinion.  This is a
fantastic group.

thanks,

Joe

KR> Laser level recommendation needed

You may be over-thinking this, if you're not building a "Super2".  A 
water level is all you need for dihedral
(http://www.n56ml.com/owings.html), and a plumbob and chalkline for 
aligning the tips to each other laterally.  Later, you can use some of 
the water level tubing to make a manometer and test your airspeed 
indicator (http://www.n56ml.com/airspeed_calibration/).  The sad thing 
is you can build the plane absolutely perfectly, and propwash will 
require you to add a trim tab to one aileron anyway.  I fretted over 
mine and went to a lot of trouble to get the same kind of plane I'd have 
gotten without all that effort.

But to answer your question, don't buy a level from Harbor Freight like 
the one shown at http://www.n56ml.com/kgear.html. After using that level 
to align both N56ML (which was perfect) and N891JF (which is on the 
squirrelly side), I recently used it at work to get some pictures 
hanging in a straight line on the wall... and noticed that the line 
curves!  It's actually an arc that bends up about an inch at both ends 
off a 6' straight line!  So there's no telling what the alignment really 
is on either plane.  Bottom line is test whatever you buy against 
something "known straight" and at least give it a "reasonable test" 
before you use it.

But for wing installation, it's hard to screw up with a water level and 
a plumbob...

KR> AGM batteries

[Phillip Matheson]

I have had the same Odyssey battery in my KR2 since my CofA 2007, and come 
to think, I used it before my plane was complete to turn the engine over 
regularly to get oil pressure up while sitting in the shed.

I have completely flatten it a number of times by leaving the Master on. ( 
silly boy)

It is still going strong.

While nice, you don't need anywhere near the kind of equipment used 
in the video to construct a KR.  I don't have time right now but I'll 
try to write something up later.  I used two bubble levels to set up 
the wing center section and came within 1/10 of one degree when 
measured later with a digital level.  I used a digital level to set 
the wing washout.  My KR flies without any fixed trim tabs.  I wrote 
something up in the newsletter many years ago but doubt if I can find 
it back.  Later.
