my friend's txt-1 has went through 3 hitec 645mg servos in the last 2 runs. if the truck even rolls on its side it seems to strip the servo. I realize this is mostly due to the sheer weight of the truck, but what does everyone do to prevent this other then buy stock in hitec? also, he is not running a servo saver due to the ones he tried didnt seem to help either. this is the only thing that i have found that looked like it might help. any help is greatly appreciated.
