I was thinking of a simple rate gyro on the nose only. What type of gain setting did you end up with on your 15?
thx Vin...
Vin,
I'm not exactly sure what the final setting was, but I'd guess it was around 50% - in rate mode only, not heading hold. The gain was fairly high in that you could move the nose side-to-side and see quite a bit of movement in the nose steering servo. I eventually sold the plane though, so I can't check it...
I had pull-pull steering as well, and the cables would go slack when the gear was up, so I didn't need to worry about turning the gyro off when the gear come up. Actually, I was using an 8-channel RX in the plane, so I could not adjust the gyro gain in flight (not enough channels) - I just did a couple of experiments on the ground to set it where I needed it and then left it there.
