Hello

I have also had some of the low cost gyro that did not work so well, so I would also caution use of those even on steering.

Let me say that I know that some pilots shun the use of gyros and believe that they are for sissy pilots . Ok I was one of those at one time, but I now like my planes in one piece most of the time and if I can put a gadget in that the similar in function to what Full scale jet fighters, and airliners use all the time I say why not. RELAX YOUR SUPPOSE TO HAVE FUN WITH THIS!
Ok enough bs.

I have used the Act Fuzzy on Elevator and aileron, works great.
The Futaba GYA 352 dual axis on Deltas “elevons” works great.
The Futaba GYA 351 dual input single axis works great for ailerons/flaperons/elevator
The Futaba GY 401 single input, single axis works great for rudder, steering, elevator etc.

The Act Fuzzy Pro is nice it has built in stick fade out. When you install gyros in ailerons it tends to make the control feel dead, as the gyro “fights you” with opposite aileron when you try and roll. Too counteract this the Act Fuzzy Pro has a built in feature that as you go away from center the gain or amount of effect the gyro has on your control is minimized so you get the full effect of the command that you are inputting.
In the Futaba gyros you have to create a mix that changes the gain “effect” channel to near zero as the stick moves away from center. I use very high exponential to accomplish this, as the stick moves away from center the gain on the gyro channel go’s to near zero very fast. However you have to be very careful not to have the mix move the control in to heading hold mode. As you raise the amount of gain you will have to change the mix to compensate, or just live with a little gyro feedback. This is not recommended by Futaba so pls program at your own risk.
I will continue with examples of gyro use in next post.
