Using gyros on R/C sport aircraft

Would the installation of a gyro on the aileron or rudder improve my
performance with my 1/4 scale J3 cub on floats? I found last summer
that sometimes I had dificulty tracking into the wind - then on lift
off the attitude could be hairy if the breeze was over 15 knots. I've
been flying for years but now at 70 my reactions aren't what they used
to be. I hope a gyro would give me that added security on take-off.
Would you recommend treating only the rudder, the aileron, or both?

I can only relate my experience with a gyro in my 1/4 scale Fokker Dr.1. The
gyro didn't move the rudder either fast enough or far enough to stabilize the
yaw worth a damn during take-off and landing. In the air, I had no problems
making coordinated turns, if needed. Do you have a water rudder? It might
need to be larger...

Re: Using gyros on R/C sport aircraft

You may want give the FMA co-pilot a try. There have been a several
reviews on it recently and from what I have read it does what it is
supposed to do. It uses Infra red sensors instead of a gyroscope but is
two axis and is supposed to bring a plane into straight and level flight
within 1 second of letting go of the sticks.

Here is a link to their site.

Hope this is of some help, Sherman

OOps! Think my first reply went to the wrong thread.
Try using Futaba's "PA-2" Pilot assist module.It's relatively inexpensive
and works very well in keeping your craft level & stable!
Good luck

From the FAQs on the Co-Pilot --

Later in 2002, a new Co Pilot system will be made available that can
handle CCPM, dual ailerons with mixing and the like. The new system
will include a standard FM, 8 channel receiver complete with fully
programmable failsafe feature. Since the new system includes a
high-performance receiver, it can access all 8 channels for flight
stabilization. This new technology will enable FMA to introduce the
world's first, true failsafe system. You will be able to program an
aircraft for low throttle and rudder in the event of radio failure or
interference. The Co Pilot will provide flight stabilization and the
model will circle in a flat turn until control is regained or the
model lands itself. Development efforts are on target for delivery in
late 2002 or early 2003. The concepts of true failsafe have been
confirmed. The new technology works.

That would be really cool!

Re: Using gyros on R/C sport aircraft

Sure would. I hope like hell it is out before that MIG takes to the air!
My son and I have talked about the FMA Co-pilot and we are probably
going to get one with the gift certificates we got for Christmas. We
think it would be handy until we get used to the ideocyncricies of a new
plane.
I had a chance to pick up one at our clubs swap meet for $50 but it had
been in a crash. The guy who put it in his plane never turned it on and
crashed the plane on the first flight. He has a tendency of crashing
planes on the first or second flight. I saw him crash 4 planes this past
summer. On that crash he didn't have the nose weight secured properly
and if fell off. We all know a tail heavy plane fly's once! :-)
BTW he is retired so he has lots of time to build planes.

Re: Using gyros on R/C sport aircraft

I have used Gyros and the futaba PA2 "Autopilot", and in my humble opinion,
the PA2 will help a new flyer to keep the model out of the dirt, but you
need to be aware of the need to keep reducing the gain till you can fly
without the "helper".
The Gyro on the other hand is very useful, especially on tail draggers to
keep a straight track on takeoff and on Swept wing models ( I have one on my
BVM Sabre) to stop "Dutch roll" common to swept wing aircraft. (all swept
wing airliners have a "Yaw Damper".
If you can fly reasonable well then a Gyro is what you want.
Get one with remote adjustable gain. Too much gain at high speed can cause
severe oscillations and loss of control.

Re: Using gyros on R/C sport aircraft

I'm using a gyro on the rudder of my Dr1 with very good results. I'm using a
very strong servo with a very long arm which gives me a quick response
(large rudder swing). I have the gain turned up max, and I shut it off after
take off...walt
