need help with servo problem
 

:confused: being new to the rc scene i recently finished rebuilding a 2.5 R T maxx i bought used. my problem is with the steering servo, it is chattering when the truck is sitting idle the sevo is kinda jumpy and it is also making a funny whining sound the truck steers fine,i have even tried to adjust the trim nothing seems to fix it.any ideas??? thanks in advance , Gary

Try switching the throttle and steering servos to help see if that fixes anything. If all the noises go away then you know the servo is no good and that it should be replaced.
