JR gyros are PERFECTLY suitable for fixed wing as well as helicopters. Yaw is yaw, uncommanded roll is just that, roll or angular motion, and both can be damped by the use of gyros, really doesn't matter whether is a heli or fixed wing. Adverse aileron yaw can easily be corrected by use of differential aileron and/or mixing rudder to aileron, you don't need a gyro to correct that !

Delgato has totally missed the point, gyros can GREATLY smooth out flight particularly in bumpy conditions, nothing to do with landing practice !! They have transformed my BobCats and both of my Hawks are ultra smooth with gyros on roll operating at low gain.

That said, I have several models with JR gyros on rudder/ns but the best dual channel, single axis gyros, perfect for twin servo aileron installations, are the Futaba GYA351 or ACT Fuzzy Pro. Both have controllable gain and can be used, switchable, in the "hold attitude" mode.
