Throttle servo on spectra destroyed X 2

[Rickard]

I have had a throttle servo, JR std that the gearbox broke .
So i switched to a JR digital servo, and the mounting ears broke on one side after 5 flights.

What is causing my servos to fail?

I use a CSM govenor, can it override the max and min settings i have in my radio?

You have something out of alignment. I'd check the motor to clutch alignment by taking the spark plug out and pulling the motor through and watching the muffler/air cleaner to see if there is any wobble coming from turning the motor around. Its possible to have an out of round delrin ball on the clutch that can cause this and make for excess vibrations.

Other things to check is the balance of the motor if its not already balanced (rotor at least).
