I have burned 3 throttle servos in less than a month.
Two in my buggy and one in my rallygame car.

I use ko propo radio system in the buggy and Sanwa in the car both with Hitec digital 5985 steering servo.

I burned one hitec 645 and one Jr 590 on the buggy and one futaba 9402 in the car.

I have my EPA set correctly so i don't know what has caused this.
Could it be that i use digital and analog servos together?
I have burned all three at the moment i press the brakes.

The Jr didn't last even a tank.
The 645 was there for 2 Gallons...same goes for the futaba on my other car.
Some say vibrations...but i used the rubber grommets.
