Hitec Hs-65MG Servos stopped working TWICE!!
Guys,
I installed 3x Hitec HS65MG servos on my Trex 450 Cyclic, after 6 flight one of them (ailerons) stop working...than replaced it with another....after 5 batteries again the same servo that was replace stopped working too. Any one of you had the same issue? or Any one can tell me why this is happening please? Thanks Ramon |

The HS65's don't like to be squeezed or twisted in the frame.
If this happens the metal gears could bind up and the servo will fail. So, if the servo fits tightly in the frame mount file/sand it out to make a looser fit. Also make sure the mounting screw holes and servo tab holes line up so the servo doesn't get twisted.

The servo sits perfectly in its hole, the hole is a bit bigger than the servo and it fits brilliant. I do not know why this is happening i am starting to believe that the servos are not original Hitec, could be?
Thanks Ramon |

Hi, I believe that the hole where the servo fits is not tight to the servo. I am starting to believe that these servos are not original or something....anyone had these problems?
Thanks Ramon |

Check voltage output from receiver at the aileron pins. Compare voltage to the other outputs on receiver. It's almost impossible to have varying voltage from the receiver, but stranger things have happened. Perhaps an increased/spiked voltage to the aileron is causing these failures.
