I learned the hard way a few weeks ago that the analog 2721 and 370a don't play well together.

so if the video say analog ok, disregard. The instruction certainly say digital only.

something to consider with gyro use is the fact the servos are basically constantly changing direction. This means servo life is reduced and battery consumption is increased. How much? Who knows....

as for what surface is the best to stabilize? I say give me an aileron gyro before anything else. I've flown the little Sabre with aileron only, I did not know until the customer told me. I figured it had rudder aswell. An aileron gyro builds confidence because the plane stays where you left it, but on the other hand it can mask a stall... Beware.<br type="_moz" />
