RE: gyro problem after upgrade G2
if the tail is drifting counter clockwise do you mean the head is spinning left? if yes, then this is really a easy fix. You got too much left rudder, simply apply right rudder and observe the tail servo arm and which direction is it moving? into the frame or away from the frame? The move the servo along the same direction as the arm to offset the drift. Trial and error and you must do this until the drift slowly goes away. WHen you move the servo on the tail boom do so in small increments in 1 to 2 mm at a time.
