RE: Gyros, whose are you using?
I use the ACT Fuzzy Pro SMM on the elevons of my Eurofighter Typhoon. It is very good because it has 2 inputs and 2 outputs, so you can use 2 aileron/elevon channels into the one gyro, and it outputs to each separately. You can manually adjust the gain, and the fade-out so that it doesn't fight against you when you want to roll. The gain also can be adjusted by radio.
