August 4, 2011Application(s): Aileron & Elevator - 50 cc MX2
Comments: 2 of four servos failed. When sitting static, control w/not move. Bumping the control (elevator or aileron - not the radio) will get the servo working again. With normal vibration, will work in flight. Both servos put on tester and on "step" mode both fail. Cannot trust them on an expensive plane.
