Dustorm. I can tell you it is not related to digital servos. I am all digital and using the same radio, receiver and gyro. Try this and let me know the result. Unplug the gain on channel 5 and adjust your gain manually on the gyro. Start at 50% (with the slot on the gain screw at 12:00 on the gyro). I am just curious if this resolves your issue. I never could get this gyro to work correctly with the gain wire plugged into channel 5 on the R770.
