Re: [RCSE] stuck on mandrel

2006-11-14 Thread Michael Lachowski
Instead of mylar, use a thin release film spiral wrapped around the 
mandrel.  You should be able to pull out the mandrel then pull out the 
release film.  You can use steel rods if you want something more 
consistent than a dowel.


Jimmy Prouty wrote:

Hi Tony,

Did you spiral wrap the mylar over the mandrel?  I've found that I can 
grab the mylar with a pair of duck bill pliers and gently wrap the mylar 
around them to pull it out of the tube.  It sticks once in a while but I 
can usually reach in and pull the stuck piece out with hemostats.


Happy flying,

Jimmy

We've been flying the DX7 tx and AR7000 rx for some time now in over 200

to Turbines and Heli's (gas/glow and electric). BTW-Turbines are THE 
most unfriendly RF enviroment out there in the RC world. And even 
sailplanes with carbon kevlar fuselages and carbon booms. Altitudes 
achieved during testing were past 2000ft AGL and not directly over-head. 
These are facts and not smoke and mirror tricks or slick advertising

this. And for those who don't well ask someone who does. The

Re: [RCSE] Full Range Spread Spektrum, the DX7

2006-10-19 Thread Michael Lachowski
The DX7 manual is virtually identical to the JR XP7202 which by the way 
has the synthesizer programmed  via the menu, not switches like on the 
modules.


I put togther a 6 servo program on the 7202 for sailplanes.  This gives 
you the following mixes/presets


Aileron to Rudder
Aileron to Flap Coupling
Elevator to Camber, full span
Two Camber Presets (Launch and Reflex if you have a TD ship)


With a 7 channel RX, you can do the following.

Channels on a 7 channel JR RX
Thro - Left Flap
Aile - Right Aileron
Elev - Elevator
Rudd - Rudder
Aux1 - Left Aileron
Aux2 - Right Flap

Setup

Wing Type - Flaperons,  V-tail as required

Switches,  Aux2 [Inhibit], Aux2 Trim [Inhibit]
Flap [System],   Flap Trim [Inhibit]

Left 3-position switch will be down for launch, up for reflex


Programmable Mixers

Aile - Rudder +10, +10  (Only one aileron to rudder mix is available, 
but you could turn it off)


Elev-Flap Mix  +20, +20 (This is elevator to camber for the ailerons)

Mix1  Elev - Throttle,  +20 +20   (This is for elevator to camber for 
the flaps)


Mix2 Aileron - Aux2  +50, +50 (Part of Aileron to Flap mix)

Mix3 Aileron - Thro  +25, +25  (Part of Aileron to Flap mix)

Note that the numbers are different for aileron to aux2 and aileron to 
throttle because the Aileron to throttle changes both flaps so Mix2 must 
negate that.  That is why the value of Mix2 is double Mix3


Mix4 Flap - Throttle +70, +70  (This is lap system preset mix into the 
flaps,  Use Flap System meny for preset settings for the ailerons)


Mix5 Thro - Elevator  0, -30, 100 Offset  (This is your elevator 
compensation for landing)


Mix 6 Thro - Aux2  -100, -100  (This is to get second flap mixed in. 
Note -100 values)



Flap System,  Use Up Flap value for Reflex and Down Flap value for 
Launch.  You can also use elevator presets in there if you need a little 
elevator offset for launch or reflex. (Or you can use reflex and camber 
if you don't need launch like on the slope)




What is missing is from the program that you normally have in a 
sailplane program:


Multiple aileron to rudder mix settings.
Change differential in launch or other flight modes
Changing aileron position when landing for crow/butterfly

You could probably trade off crow mixing of ailerons with aileron to 
flap mixing if you wanted.

Re: [RCSE] Full Range Spread Spektrum, the DX7

2006-10-19 Thread Michael Lachowski
The 6102 really can't handle more than one flap very nicely.  The 7202 
program and DX7 is a lot nicer than the 6102 and far superior to the DX6.


Still, there is nothing like the 9303 for sailplanes

For those who like toys for the bad weather, check out the Blade CX2. 
It has Spread Spectrum RX instead of the old 4-in-1 unit.


If you really want to deal in speculation, check out
http://www.vit.or.jp/~tomo/gami/tokyohobby2006/tokyohobby2006.html
for your picture of the JR 12X which looks simlar to the 10X case with 
the 9303 display and cricket for the user interface. And the display has 
3in1 12ch inbetween the japanese text.

Geez.  You gotta learn to relax a little bit.  This radio isn't

If you look at the JR line of radios you will clearly see that they know 
the difference between airplanes and sailplanes.  Wait for the sailplane 
version and I think you will find it more to your liking.  Of course you 
could by this on and live with a few limitations if you wanted to.  I 
know a number of guys who 'saved money' by buying the 6102 to fly their 
sailplanes.  Now they want to know how to make it do all those sailplane 
things.


I am heartened that their descriptions of its range capability includes 
unlimited sailplanes but I wouldn't take that to mean that this 
particular radio is targeted at that audience.  I would take it to mean 
that they can release a sailplane version at some point.  I'd be real 
surprised if an equivalent to the 9303 isn't in the works.

Re: [RCSE] DX7 range

2006-10-19 Thread Michael Lachowski
You're dealing with two receivers for redundancy.  The AR7000 is 
actually split into two boards with about a 6 inch connection between 
them so the two RX can get different RF environments.  I guess you 
could throw one in the fuse and one in the wing on a sailplane. I don't 
know if you can extend the connection between the two boards.

I have to question this too, because 2.4ghz is limited in power output
and it doesn't travel (propagate) well. I know people are having good 
results

with these radios and I wouldn't hesitate to use one on any small
airplane that would be within 1000ft.
I have personal experience with video feeds on both 2.4ghz and 1.2ghz.
and 1.2 has much better range, but both freqs. will not go through trees,
so if you fly behind a tree and the radio doesn't have last frame hold you
could completely go out of control. real world use will decide if this is an
issue or not, but the bottom line is that high frequencies at low power have 
poor
range and there is a lot of stuff on 2.4ghz to screw up your signal when the 
primary

signal is lost.
I would really like to see spread spectrum on 72mhz. but it probably isn't a 
high enough

frequency to work at a high resolution
All of that being said, if they made a module for my 9C, I would buy it in a 
heart beat...

If I want a challenge, I fly F3b.  2M is nonexistant on the east coast.
As long as they stick 2M in the middle of the week, I'll fly it to pass 
the time.



I'd rather see 2 days of RES than 2M.

Another way to look at it is if you throw enough ducks at a problem, 
you'll find one that works.  I'm happy that everyone else likes to fly 
Ducks.

I would take note that the Organic was the 2m ship prior to this year.  At 
the Nats, there has never been any ship with greater numbers than the 2M 
Duck.  The Organic in many areas holds sway cause of it's availablility, and 
it is a decent ship, but Ducks have always had the numbers behind them here.

Yep, agreed. The Organic was the best design that was readily available. But despite the maximum difficulty of getting a Duck (I saw a used one for sale for $1000),  many top pilots have gravitated to it since it first appeared, because it has the right design to win 2M. That's what's interesting to me. Its low AR, fairly high wing loading, and high operating CL are all at the opposite end of the  spectrum from the current fashion in Unlimited, where light planes with long, skinny, thin-section wings flying at low coefficient of lift are appearing all over the place. 


I guess it proves that in theory, there is no difference between theory and 
practice, but in practice there is.

A very fine post in its entirety, Jim. 2-Meters is a world unto  
itself, and when good flyers go at it, it's a very worthwhile  event. 
You have to launch to the moon, then find lift quick,  because the 
little planes come down in a hurry and don't travel  well if you hit 
sink.


The dominance of the Duck design seems to me to have some  
interesting implications. U.S. flyers generally have disdained V- 
tail airplanes, but the Duck shows that they can learn to love 'em  
if the tail is big enough. Additionally, the Duck has a fairly low  
AR wing and is pretty heavy; these characteristics don't match the  
current fashion, but in this class they seem to prove out to be  best 
in practice.


It would be neat to see a resurgence of interest in 2M, just to see  
what other design tweaks might come along. It seems that there  
hasn't been much design activity in this class since the Organic  and 
2M Mantis. Maybe there's a world-beater out there to be  discovered.

For all the transmitter impaired, you can also get a R720 FM RX from JR.

Re: [RCSE] Got the New Fusion Hitec 9 Channel Synth IPD RX Yesterday!

2006-06-04 Thread Michael Lachowski

Why turn off the IPD filter.

Just pull full up in the elevator and walk away until the elevator 
returns to neutral if you have hold set.




[EMAIL PROTECTED] wrote:


Its different and from the MPX leg or Hitec's engineering.
 
IF you have had one of the MPX Synth RX's you already know how to 
program it.
 
One neat feature is that you can turn off the IPD filter, for doing 
ground range tests.


The IPD acts sort of like PCM in that when the signal is lost, it either 
goes into 'hold' or to a failsafe preset you have assigned (some guys 
like full up elevator, so a signal loss at altitude makes the plane loop 
in place, other like a version of full flap with a touch of extra 
elevator so that the plane stays really slow, and flares with any added 
airspeed).
 
The Fusion lets you program any fail safe setting with out having a 
special TX...any TX works, just hold the stick setting and touch the 
'set' button per instructions.
 
One thing I found interesting was that you can use the IPD filter or 
not, without its just a standard FM crystal-less RX, with it, the micro 
processor goes to work specifically identifying 'your' TX...not just the 
frequency.  It verifies that the same TX is being used as when it was 
programmed by checking to see a couple of factors like number of 
channels that was being transmitted are still there, and the 
'fingerprint' of the signal..sort of.
 
One other thing that I found interesting...was that the 'frying eggs' 
noise that synth RX's tend to cause digital servos to make, went away.
 
Won't have a chance to try it on the field till tomorrow for range tests 
in both standard and IPD mode.  So far IPD and DSP tricked out RXs have 
not been a good thing for us sailplaners, so fingers crossed on this 
one. Its very compact and price right too for 9 channels.
 
Right now in order to change Freqs or access programming, you have to be 
able to put a poker into the Set hole in the top of the RX caseoften 
our installs don't allow easy access to the case of the RX, so I have 
already figured out an easy install on a remote button for the set 
function :-)

Saturday afternoon had some really excellent lift.  There was one half 
hour period over the field where there was very strong lift over a very 
large area. When you do two rolls with a 5M sailplane and you don't 
loose altitude, the lift is big.


Skip Miller also took advantage of some of the excellent lift on 
Saturday afternoon, clocking in 73 miles on the one flight.  The XC 
course was about a mile away from the launch area. I could see the 
models on course, and there were times where they made about a half 
dozen circles and doubled thier altitude before continuing on course.

Well, I paid a brief visit to the third JR Aerotow today and here are
some observations:
- I know the connotation, Fun Fly, is currently in bad repute but I've
been to all three of JR's Aerotow events and must say that the fun while
flying seems to maximized at this event.  Smiles all over the place.
- For those concerned, Butch (that's RCButch) is doing quite well in
spite of his advanced years.
- Bernie Coleman complained that the combined overcast created by Jim
Porter's 6 meter Orlik and Doug Barry's 6 meter Minimoa was ruining the lift
for everyone else.  Here's two sailplanes that really look great in the sky.
Seeing them together was a real piece of eye candy.
- Nice to see Jim Frickey with a 6 meter Ventus.  He notched an hour
flight on Friday.
- The most creative use of a large sailplane fuselage had to be the ice
bucket at the Castle Creations tent.  I hope someone posts a picture.
- Missing the action so far were Cap'n Jack and the SOAR guys.
- As I stated earlier there were lots of smiles around but the biggest
smile I saw belonged to the owner of the Multiplex Easy Glider that was
painted and trimmed to sort of resemble a scale sailplane if one squints a
bit.  With some somewhat aerobatic help from John Berlin who was handling
the sticks on the early part of the tow, the Easy Glider owner really was
enjoying the benefits of a high tow and good air.  His grin was as big if
not bigger than those of the owners of the big bucks ships.  Way cool!!
Nice work JR and all involved - keep up the good work - see you next
year!
If you've never been, there's still time to drop in to Monticello,
Illinois and take a look tomorrow.

Re: [RCSE] F3B (team)

That's up to you to choose how to fly and how much input your team 
provides.  Yes, we all use input from our team members, but we're still 
the pilot in command of the aircraft and have the ultimate decision on 
what to do.


Most TD pilots always have a team.  Ever notice how many guys always 
have the same timers/callers.  That's because you've worked together and 
know what the other guy wants and needs.  Nothing is more distracting 
than having your timer argue with you that you should be counting down 
on landing approach if you happened to like actual flight times.

Now that most of the smoke has cleared, where can we find more out about 
F3B;



3. how do you get started?
Just like anything else in the hobby. It helps to have some others 
around to assist you.  And it helps even more to have a group that flies 
together. This lets you practice some of the man on man aspects, plus a 
little friendly competition in practice on who is launching highest, 
going fastest, etc never hurt anyone in improving thier model setup.


And of course, RCSE doesn't hurt. Obviously there were quite a few 
responses. Mostly from guys who really love to fly F3b. There really is 
no way to explain what it is like to fly distance and speed to someone 
who has only flown TD.  You can be descriptive and say what takes place, 
but until you've flown some good distance groups and done it is some 
good air, you just don't know...



4. what airplanes qualify?
Almost anything qualifies. Lots of TD models are out there with MH-32's, 
RG15's, etc. They are good enough to get the feel of the tasks and to 
learn a lot about flying.  Like models will go up without circling 
You can even fly a Supra in F3b.  And if you go to ancient history... 
you can use a woody.




5. about how much dose it cost to compete?
Like anything, as much as you want.  The biggest cost is the practice 
time you need to improve your flying skills.  You can buy a good model, 
but it doesn't replace the practice required to learn to fly it well.




6. on average how many people do you need to run a contest?
Most F3b contests get run be the people flying them.   If you read the 
rules, it looks like a billion officials. But just like our AMA TD 
contests, you don't need most of them.  The only big overhead help item 
is getting guys out to base B for the distance flights. Your own helpers 
at base A can usually keep track of the flight times and count laps.


There are a few F3b buzzer systems in various places around the US. Some 
of them even take care of all the timekeeping and lap counting. The only 
thing official needed is someone at base A and base B to push the 
appropriate buttons.


And yes, you can even fly the F3b tasks in a contest all by yourself. I 
wouldn't recommend it, but it has been done.






What you didn't ask is what can you learn from flying F3b.  Of course, 
we all abuse Jeff Steifel, about his flying.   But his overall flying 
has gotten better since he has been flying F3b.


If you've never flown on monofilament and a F3b winch, you probably have 
a lot to learn about setting up your model for launch. I have several 
F3b winches. Great to launch my Bubble Dancer as well as my F3b models. 
Got rid of my FLS decades ago.



I hope you get a chance to meet up with Dave or someone else in your 
area to give flying off some F3b winches a try.  And you still have time 
to change your NATS entry from XC to F3b!

Re: [RCSE] Durable Paint?

Klass Kote is almost the same as KB.  Good stuff. It's what I use for 
paint when making molded models.


Imron is ancient technology in auto paint.  Why take the risk.

George Voss wrote:

Imron is supposed to be painted in a sealed room with more than normal

Funny isn't it, all the really good stuff will kill you.  Now we get watered
down stuff, like Krylon and have to consider it a 'good' paint.  


Go with Rustoleum or Klass Kote.  Me, I stocked up on KB as soon as I heard
it was going off the market.  I've got just enough to last me until I'm done
with this hobby in my 80's or 90's. ;-)

Worse than a carcinogen is that Imron is additive and will destroy your 
liver. It never purges from your system. I have heard about guys that 
died after spraying IMRON too many times without a respirator..
Always spray with at least a basic volatile orgranic filter respirator 
or a pump. I happen to have both.. The pump style of respirator is also 
excellent for 2 part systems...


I agree about Krylon being too soft... white nearly turns black by the 
end of a couple of flying sessions and can't be cleaned off.


George Voss wrote:



Frankly, I hate Krylon.  It scratches easily and isn't very durable in my

For the best paint, use Imron.  The problem with it of course is that it's

you can find some.

Klass Kote is the best paint currently available.  It's expensive and


you'll

need at least an airbrush, but a small spray gun is better.  


As for surface prep, I sand or scrape the joint line and wet sand the


entire


nose cone with 600 or 1000 grit sandpaper wet.  Use 3M fine line masking
tape.  It's a type of plastic and it stretches around corners fairly well.
If you are shooting over white and you are using a dark canopy color, you
can shoot a dust coat, wait 15 minutes, shoot a flow coat and remove the
tape while the paint is still wet.  If not, use white primer over the


canopy


area and then shoot the color.

Let the painted nose cone sit in a heated area for 3-4 days untouched.


Sand


the edges of the canopy so they blend in with the nose cone.  I put 3M
pinstripe tape around the paint line and then clear coat the entire nose
cone.

I've got some photos of a finished nose cone if you want to see one.

If you want a rattle can finish, use Rustoleum.  Be aware that you will


need


to allow the paint to dry in a heated area for at least 3 days before
handling or you will get fingerprints.  Other than that, use the same


method


as above except heat the spray can with hot tap water prior to spraying.


It


will keep the paint from shooting blobs out of the nozzle.  Also, if


maximum


finish points are desired, use a new can of paint.  Sometimes old, used


cans


will shoot blobs out, even when heated.

Wow, solid state, haven't heard that in a while.

The TX does take a lot of abuse.  Getting dropped, knocked around. 
Antennas get pushed and pulled all the time. (As anyone with a Vision

 There is dust, dirt, humidity, lots of things that can eventually find 
there way to the right place.   Running TX with the antenna down might 
produce some extra heat on the RF output electronics.


All the materials in the transmitter can age which affects thier 
performance. Plus mechanical problems like switches and pots wearing out.



Of course, given the types of comments on this topic, there are lots of 
folks out there who just keep running things until they break.


SOme people check thier batteries all the time, others never check them. 
  It's no fun loosing an airplane to equipment failure. You just have 
to decide how much time you want to spend preventing equipment failures.


Anyway, it's almost spring.  Time to start checking out your models that

Hobby Lobby also has some nice metal horns that are aluminum. They are a lot

Re: [RCSE] Wind Question - Not for Sport Fliers

2006-02-20 Thread Michael Lachowski
It doesn't need to go up to 11 oz loading.  Especially if it's only a 
10mph wind.


Best thing to do is start experimenting.  Try adding 6-7 oz to the 
model.  Make up ballast so you can also go up 12-14 oz.


Thin airfoils don't need the huge increase in weight.

At that time of day in the winter, any lift will not be strong but you 
will notice the difference.  Most likely you were not drifting fast 
enough with the thermal.


[EMAIL PROTECTED] wrote:
RE: Your wing loading seems to come out to 6.65 ounce per square foot.  
Im taking your 525 sq. in. and the  22.5oz plane flying weight . Thats 
very light for  any wind performance.If those figures are credible, 
I would suggest trying to fly at a wing loading of 11oz. sq.ft. when 
your sure that thermals are abundant  in those 10 mph wind conditions. 
So if my math is right, that flying weight using ballast would be 39 to 
40 ounces total  flying model  weight .  Geez, that sounds heavy, but 
your starting out very light!   And   2 meter models dont have 
stellar performance to start with.  

Just a note here,  When I get chances to assist guys flying those super 
light models,,,  I find it more difficult to read air  even in a  no 
wind condition because the model is milling around, like cows grazing 
in a pasteur; and not covering much airspace,  I prefer to mustang 
horses galloping on an open range.Specifically,Im talking about 
those 8 and 9 ounce wing loading types.  To make matters worse if thats 
possible some of those models are really nose heavy too!


Now  a point of interest Ill state here is not all airfoils like 
ballast.  The airfoils that come to mind are: Clark Y, Eppler 205, SD 
7037.I think those are all higher camber wing airfoils.   My 
experience with those airfoils is the more you ballast, the faster they 
come down.I also found that happening  to some extent on the Pike 
Superior and that is why I dont fly one any more. Although the v-tail 
flew, penetrated ,, the wind better than the crosstail!


So,  If you are sure that there were thermals that day,,,  Is the reason 
you werent happy with your acheived performance, the following:  1)your 
plane set up, with regards to balancing?  2) your plane set up with 
regards to coupled aileron differential and rudder throw.  3) your 
airfoil?   4)the wing loading too light? 5)the pilot?   6)  
There were no thermals?  7) Or the thermals were not strong enough 
to support your model?  You said 5:00p.m., which is quite late in the 
day for good thermal organization,, Especailly at 35 degrees  F. 8) 
It was a 2-meter?   Thermals,  Richard Burnoski




Richard,

OK, you did say you would answer questions if asked...

I just went out to practice.  A bit of detail on the plane first. It is an
Allegro Lite 2m.  If you are unfamiliar with the plane you can think of it
as sort of a mini Ava.  525 sq inch wing area, the plane weighs about 22.5
ounces in the electric configuration I practice with.  Right now, it is my
highest performance plane.  It is also very convenient to practice with as
it assembles quick and is electric.

OK, so in southern Indiana at 5:00 today after work it was about 35 degrees
and the weather site says about 10 mph wind from the North.  I could
definitely find patches of lift.  And at times it seemed strong.  I noticed
this both on the climbs and in glide.  But it seemed every time I tried to
wrap it I would loose altitude.  Sometimes when flying into the wind the
plane would speed up quite a bit and gain altitude, something I normally
associate with entry into a thermal.  So I attempt a wrap but that was 
never

successful.  I started to get cold and packed up but on the drive home I
thought perhaps instead I should have just tried to float through those
patches or perhaps S turn in it kind of like slope lift.  Definitely from
the ground there seemed to be times when a thermal would pass through.   
Any

thoughts on flying in these conditions?

Ryan

Sounds like Don's tradeoff is a good one in overall airframe performance 
especially since the launch is such a small part and the only time the

For a typical F3x airframe, in order of importance, the most effective means of

1)  5cell NiCD (not NiMH) PWR supply
2)  Digital servos

The estimates you ask about would be different for every installation. However,

Re: [RCSE] Lachowski Pod For Sale

2006-02-04 Thread Michael Lachowski
Yes, Terry's fuselage has a very long nose moment. That would be the 
longest of the bunch.  It will help if you have a heavy tail or need a 
really long tail moment.


The longer Supra pod I make is plenty long enough to balance a model 
with a reasonable tail.  With a light tail, you have to make sure you 
don't put in too heavy of a battery pack.


The shorter pod usually requires a little nose weight.  It is also 
smaller, only 2 diameter.  It also penetrates soft ground really well. 
 So if you are in the part of the country that gives 0 landing points 
if the tail isn't on the ground, it's a bad choice.


I like the shorter pod better for landings.  Long noses tend to have 
more spring in them and bounce more.  Unless you put on a shock 
absorbing nosecone.  Terry's fuselage is well suited for that setup 
since the nose just slides over the pod.

go with that pod.

That is the smaller pod, the size that Mark Drela and Tom Kiesling 
have on thier models.  It has a shorter nose moment than the one that 
most guys have purchased and what Phil is using.

Re: [RCSE] Re: Wood Crafters / Builders etc.

2006-01-29 Thread Michael Lachowski

Designing the aero part doesn't matter, wood or composite.

Desigining the structures is similar, but the wood structure is more 
effort.  Same with building.


Many of them end up with glass fuselages anyway so it's a toss up.
Both end up with carbon spars.  That's a no brainer if you want to winch 
launch anything.  If you were just doing electrics, you can still build 
a wood wing if you want to carry the extra weight.  But building a 
really strong wood wing takes a lot of material.


They all end up composites anyway.  They all use epoxy to some extent. 
Wood is just some cellulose composite structure anyway.


What's disappointing is the lack of effort on the composite side.  It's 
an american thing.  Everyone wants to do everything themselves but doing 
a full molded model works out better if you have different people doing 
different parts.

Press Release
US Soaring Masters.
The goal for this event is to help stimulate the competition soaring
segment into higher levels of awareness within the modeling community.
Soaring has endured many years with no real push to grow the segment. With
a prestigious international event, that will draw out the best pilots from
not only the US but the world, could only help grow the great sport of
competition soaring. IMAC has seen much growth, which is no doubt partly
due to prestigious events like TOC, and the Don Lowe Masters. Scale has
also seen great growth with events like Top Gun and the US Scale masters.
The Electric segment has seen growth with events like Neat and SEFF. Giant
scale has seen growth with events like Joe Nall, Dogs and the IMAA rally's.
Soaring needs it's own high profile event. An event that will be the one to
win, an event that brings the soaring segment in front of the average
modeler, an event that gets people excited about soaring. This event is not
a fly in, it is a pure competition, with rules designed to choose the best
thermal pilot in the world. This event will aspire many to get involved in
soaring and aspire them to higher levels of soaring skills.
Dates:
September 21 - 24 2006. The competition days are Friday, Saturday and
Sunday 8 - 5. Thursday is setup day.
Location:
AMA Headquarters, Muncie IN. This site will be ideal due to the ability for
360deg winch setup.
LSF Involvement
LSF has agreed to support this event is in the form of manpower and
equipment. The LSF has agreed to run this event through utilization of
their staff and equipment. Additional Horizon staff

short quick zoom/ping off the line always results in higher launches for 
me.  Ride that zoom deep into the bucket and perhaps youve lost much of

what are you guys doing to kill the flat wing servos?



Ford Long shaft winch, strong winch battery, short (600ft?) 240 lb 
test braided winch line, no retriever, bit of a breeze. All of that in 
combination with an agressive (even abusive), unpracticed launch style 
that generally involved diving too deeply on the zoom and most 
importantly a model with very heavy ailerons that had a strong 
tendency to flutter.


Just ask anybody that attended last June's LISF (Long Island Silent 
Flyers) contest. They will tell you what a Pike Superior SL sounds 
like when the ailerons are fluttering so violently that the entire 
wing is twisting to very odd angles. This happened repeatedly even 
after switching to DS368 servos. The HS5125s stripped on the first 
launch. The DS368s survived a few of those launches although the 
lighter servo arms did not survive, the servo mounts did not survive 
and finally, after going beefy on the servo arms and on the servo 
mountings, the control horns in the ailerons ripped out. I kept trying 
to beef up the aileron servos and mountings because I was stuck on 
Long island with only the Pike to fly and it was my mind-set that 
molded models were buy and fly and the Pike was an F3J model that 
should be able to handle any launch you can give it.


It isn't pulling hard on launch that strips the gears. With the Pike 
Superior SL it is the going really fast that does the trick. The 
biggest problem on that particular model seamed to be that the 
ailerons were really heavy which is bad from a flutter perspective. 
David Hobby (current F3J world champion and Pike flyer) suggested 
using longer horns on the ailerons. I never tried that since I sold 
the model first.

Did he ever measure the current draw on his model.  If you have binding 
surfaces, you are going to be pumping a lot of current through the 
servos constantly.  A 6-servo model at idle should be under 100 ma total.

Re: [RCSE] Supra

2005-12-27 Thread Michael Lachowski
Correction.  I DO NOT have a Supra.  My models are a little smaller and 
have a different airfoil for F3b. I just do a light layup for F3j/TD 
around 60 oz.  Doesn't quite have the hang time of the AG4x series, but 
it will go fast.


You can blame me for the fuselage pod on Mark Drela's, Tom Kiesling, and 
Phil Barnes models.   Mark and Tom used fuselages pulled from the first 
mold made from my F3b fuselage plug which is set up for a different 
airfoil and a flat center panel.  Phil used a different fuselage that I 
did with a little longer nose and the top of the pylon done for the AG40 
and a little dihedral in the center.  I've used this longer fuselage on 
my TD layup of my F3b model to cut out a little nose weight since I had 
a molded tail which I haven't managed to build as light as a bagged tail 
yet.  I also used a really light layup of the F3b fuse with a canopy 
setup for my Bubble Dancer.


Some day I may have a Supra if a mold ever appears with the longer 
center panel of the design vs the shorter center on Kennedy Supra. And 
it would probably have the smaller pod on it.  Phil's Supra130 also ends 
up changed a little.  Production changes designs to suit constraits of 
the materials or shipping.


Phil does have the longest tail boom of any Supra.

Drela Supra
http://www.rcgroups.com/forums/showthread.php?t=320761highlight=supra


Here is my unofficial take on what is a Supra, gleaned from my hours 
of research:


There were a handful of people building there own Supra before Kennedy 
got his into production, and there are many ways to skin a Drela 
sailplane to mix metaphors...


The Supras that were at the NATS this year (Kiesling, Lachowski and 
Barnes) were most-likely modified slightly from the Drela design for any 
number of reasons.  Mark likes tiny fuselages and some of his 
construction techniques are a bit too time consuming for mere mortals.
The basic parameters of the plane stay the same, the construction 
techniques often differ due to time/material/builder peculariaties.


AFAIK, the wing airfoils stay the same - AG40-AG41-AG42, and most of 
the Supras out there are bagged wings.  Mark's original Supra was 48oz 
and Kiesling said he has three:  two 58oz models and one 64oz model, all 
of them bagged wings.


As far as wingspans and such go, there might be some confusing the Aegea 
130 wing with the Supra wing.  The Supra wing is the evolution of the 
Aegea 130 wing (which Phil makes for the Mantis).  Mark explains the 
differences between those two wings on this page:

http://charlesriverrc.org/articles/supra/supra.htm

I've never heard any discussion on changing length of the tailboom, but 
the fuselages are often resized as Mark's fuses are tidy affairs with 
little wiggle room.  Also, I don't think I've ever seen or heard of a 
Supra that doesn't use that sweet little V-mount horizontal stab.


I have read quite a bit about spar and wing construction alternatives, 
though that could easily take days to sift through.


And finally...

There are a few folks producing individual pieces and parts for the 
Supra...  Les Horvath of CompuFoamCore.com had a fuse/wing/tail core set 
for sale and Bud Elder makes those v-mounts (in varying sizes!).  From 
time to time you'll see folks offering up Supra fuselages, but they come 
and go.  The bottom line is that if you really want to *know* about the 
Supra, go and read through the links I've posted, specifically the Yahoo 
group.


End of last fall, I put together an Aegea Mantis w/ a Luckenbach 
fuselage and Phil's Aegea 130 wing.  It's like a poor-boy Supra.  A lot 
of the same ideas, but different, and cheaper (and heavier).  One day I 
might get my homebrew Supra together.



James V. Bacus wrote:

I have read about the Kennedy molded Supra on the web page, but isn't

It seems when people talk about a Supra (glider) it could mean a lot 
of different things.  Different fuses and lengths, different airfoils, 
different wingspans, different wing construction (bagged or molded), 
etc...

I use a JR6102 for slope and park flyers.  Nice package and 10 model memories
and digital trims with a decent amount of programmability.  It's not going to
do your 6-servo sailplane, but for anything less, it works just fine.
I have it in some models with flapperons, flying wings, and electrics.
Only other limitation is it's not a module setup like the higher end JR
stuff.

Re: [RCSE] For Sale Hitec Digital Servo Programmer...AND it....

2005-11-27 Thread Michael Lachowski
If you just want servo cycling, centering, and exercising the servos, 
the JR Matchmaker is a little less expensive at $29.95.  Also nice if 
you are matching two servos on a control surface. Not that common on 
most sailplanes, but a possibility on a scale ship or aerotow tug.

I have one Hitec HFP-10 digital servo programmer and servo tester.  It is

digital servos to factory default.  Photos available  $95 shipped to your
location. Walt
 
...And it lets you do some good things with any other servo, digital or 
other wize.  For instance, you can use it to exercise servos or surface 
hinges...by simply clicking on the cycle mode...any servo brand. You can 
use it to center any servo for installs, instead of having to radio up 
to get linkage lengths and surface centers.
 
If you rig in a small amp meter you can check each servo's load while in 
the plane. 

The Hitec is self powered, has a rechargeable battery inside and 
any wall bug will charge it.
So if you've been looking for something to control your servo's outside 
the radio during set up, the Hitec works.

Re: [RCSE] 9303 or 10X Programming assistance

2005-10-27 Thread Michael Lachowski
That will work OK.  You will probabably have to use a Y connector or 
matchbox to run both the spoiler servos and use a mixing curve to do the 
throttle stick to spoiler mixing.


I have not tried anything like that on a 9303. You only have 9 channels 
there and obviously you have 10 servos in the 8 wing servo model. But 
with the modified channel output pattern for the sailplane configs, you 
should not have much of a problem using all 9 channels.


If your flaps will always be used just as flaps (never ailerons) then 
treat the outter ailerons as the ailerons, the inner ailerons as the 
flaps for your normal channels.  Then use mixers to create the flap and 
spoiler mixes.


Now all you need are retracts and tow release...

I've got 2 sailplanes that I need programming assistance.  They have 6 
and 8 servo wings.  I'd like to have them programmed like a normal 4 
servo wing in a competition sailplane, with the addition the following:  
The 8 servo wing has spoilers, inner and outer ailerons and flaps.  I'd 
like to be able to allow the outer ailerons to always work as ailerons.  
The inner ailerons will work as ailerons part of the time, then I want 
to be able to flip a switch or go into a flight mode and have the 
ailerons cambered with the flaps.  I want the ailerons to come down ½ 
way with the flap stick, then start going up.  At the ½ way point of the 
flap stick movement, the spoilers come up.


The 6 servo wing doesn't have spoilers, and I want to be able to do the 
same thing as above.  Does anyone have a 9303 or 10X programmed to do 
this type of mixing?  It would save me a tremendous amount of 
programming time and headache.  TIA  gv

Try West Systems fillers.  The 405 and 407 would be suitable for

Re: [RCSE] How to vacuum bag fiberglass cloth over balsa

2005-09-21 Thread Michael Lachowski

Check out http://home.paonline.com/hayman/video.htm for a good video.

The cloth is placed on the mylar and wet out on the mylar, not on the 
balsa.  It's a lot easier to wet out that way with an appropriate amount 
of epoxy.  If you wet things out on the balsa, the wood will soak up a 
lot of excess epoxy and you will end up with a very heavy tail.   The 
only thing you will wet out on the balsa will be the leading edge if you 
want the glass wrapped around the LE.  That step is necessary for foam 
cores, but you really won't need to do that on a solid balsa stab.


glide wrote:

release, etc.  How do I go about it in prepping the balsa tail and
fiberglass cloth?  Do I go ahead and trim the cloth to as close to the size
of the v tail pieces, wet the cloth out, lay it on the balsa, then stick it
in the bag with the Mylar sheet over the balsa/cloth pieces?  I would really
appreciate some experienced insight on the process.

Re: [RCSE] Long music wire????

2005-09-13 Thread Michael Lachowski
I can't think of any reason to be using 1/16 music wire for pushrods.

Either use 1/16 carbon fiber rods or use hypo tubing.  

If you want 6 ft long straight wire, Small Parts does sell stainless steel
white in those lengths that is already straight. With a well supported,
straight pushrod, you probably only need .030 wire or possibly less.

Any of these alternatives will be much lighter than 1/16 music wire.

[RCSE] Servo wars

2005-09-06 Thread Michael Lachowski
Get out your JR MatchMaker, mount your two favorite servos and connect them
together.  Power it up and see who wins. 

If you don't know what a JR MatchMaker is, it's a servo tester.

Two output channels can be controlled directly from a pot on the device.
The other two output channels sweep from end to end with the sweep speed 
controlled by the pot.  Great little widget for checking your gears if 
you think there might be a problem in there.  Same size as a small RX.
I also measure the current going through it with a meter if I suspect 
a servo is not running correctly or drawing too much current.

You'll have to come up with something else if you want to do servo
drag races...

Re: [RCSE] Lamenting the lack of available sailplane builder's kits

2005-08-08 Thread Michael Lachowski
I don't think this is unique to sailplanes.  In all areas, most of what 
you get is ARF.  Overseas labor is so cheap, you get complete models for 
the price of making a kit in the US.  And the vast majority of pilots 
don't have any time to build anyway.


You can find a few kits at polecataero.  And skybench has plenty if you 
like nostalgia. But designing a high performance full house model in 
wood went away 10 years ago.  You can find fuselages out there and there 
are some good bagging videos if you want to scratch build.  Check out 
the Charles River RC site and pick any one of Mark Drela's designs and 
build it. You won't be disappointed. Just don't try to improve on the 
structure or materials selection.


Maybe a little building will come back with the current exchange rate 
for the Euro.  That has bumped up the price of the imports a lot. Gone 
are the days of a $600 fully molded model.

I prefer to build my own aircraft; no ARFs or ARCs for me.  I'm

are from kits that I acquired some years ago.  The Alcyone 3M was in
production when I got the kit as a gift, and my guess is the particular
Prophet kit I have was kitted in the 1980s; I acquired it from someone
who sold me a pair of Prophet kits: one a 2m, and the other a 2.5m.
Neither the Alcyone series nor the Prophet series of kits is in
production today, and that disappoints me.  When I started building RC
sailplanes in the mid-1980s, builders' kits abounded.  Nowadays, if it's
in a box, it's probably an ARF or ARC.  I have plenty of sets of
full-sized plans to keep me busy scratch-building for a few years, given
my slow rate of production.  But it sure would be nice to see something
like Harley's Genie in a builder's kit (I plan to build one from
scratch, given that I already have a set of cores for it).  Do any of
you remember the Sailfish or Heat Seeker or Jouster or Runaway?  You can
get the plans for these sailplanes, but you can't get them in kits.  
 
What has happened to the kit market?  Are there no profits in the kit

Turnout looks a bit low for this WC.  Several countries that were there in 
Germany are not at this one. Things are moving pretty well with 4 rounds
complete.

I haven't found any good blogs or annotated pictures.

Same group seems to consistently have the best speed times. Don't know
if that's the Lucas motors vs Bosch or something else.

Translating the germany site, looks like they have had a bit of wet
weather there.

Looking at bulletin 2, they are supposed to be at the Sauna this evening.

[RCSE] F3b WC

2005-08-02 Thread Michael Lachowski
Results are up for 2 complete rounds. Looks like things are moving pretty 
smoothly.  They also have a picture gallery for Sunday and Monday.

Looks like speed conditions weren't that good in the second round.

Re: [RCSE] NATS NOS

2005-08-02 Thread Michael Lachowski

I think it was a sweep by Whaleaires..

Go to the LSF site and Nats 2005.

It's not obvious, but if you click on the second column, Event, you go 
to a page that has a link to the results.

Re: [RCSE] National Fun Fly

Isn't Woodcrafters kind of a fun fly?  It already exists.

Lancaster has the same problem.  I would venture to say, if there was a 
National Fun Fly for a week, there might be a good turn out.  It doesn't 
even have to be on the same schedule as the NATS.
