Throttle servo chattering???
Got my son a 2.4 TQI transmitter and reciever for christmas, when he installed it and reprogrammed everything for use in his JATO, he said he gets a chattering in the throttle??? its all brand new so what could be the issue?? I suggested he re-bond the transmitter and reciever several time cause i had issues of mine going out of range and shutting down from time to time, but never any chattering in the servos that i can remember.
I'm not very good with servos but I know mine chatter if they are not returned to neutral positions. I also read a lot about traxxas servo issues right out of the box.
