These Micro Servos are not reliable. I had on fail (sticks) on me during preflight so I switched it from the elevator to rudder. Then on the next flight the elevator servo and one aileron servo failed in flight. Was lucky to get help from an experienced RC plane flyer who was helping me with the test flights.
