November 6, 2017Application(s): 90 size nitro helicopter cyclic servo
Comments: I used same servo long ago in a 30 size trainer for aileron control and during the flight the servo was stuck. same problem I experience again with my 90 size nitro heli and cyclic servo stuck again. after investigation after removal the gears I found that the motor was dragging with hand spin. Previously with the trainer mentioned above same problem was occurred and after dismantling the motor found the cores were damaged and contacting with magnates. I feel this was very unpredictable failure and could cause a model to be crashed without any sign of malfunctioning.

Comments: This servo got a workout about every weekend for a year on my Raptor 60 and I never had any complaints. Solid servo.
