I was using them for steering and throtle. the first one that went out on me was being used on the throtle. I sent that one out to be repaired so i bought another one. then my steering servo went out and i replaced it with the one that I got back from hitec.it then failed. the gears are not stripped. no i do not use abs. yes i do know how to set epa correctly. i'm not a rookie. It seems to be a motor problem with the servos. The servos are a hs645mg and a hs625mg. and no, the servo saver is not to tight. i used a jr plastic geared servo to finish out the season. I have heard many other complaints from racers at my track having problems with there hitec servos. I would like to think that you do not have to spend $100-$120 to get a servo that you can depend on. I choose hitec because the price was right and the guy at the hobby store recommended them to me as a good servo.
