RC Driving Style
I have an RS4 3 and it started acting crazy on me...i barely hit the throttle and it goes full throttle and will not return..I thought batteries...no they are fresh..plus if the batteries went bad....wouldn't the fail safe stop it....then i thought the fail safe might be bad also, but i took it off and it still did the same thing....I am thinking it could be a servo or something....Please help... thanks
 
Sounds like a servo problem to me. Also, don't rule out a bad receiver. Check the cheapest soultion first ... servo lol
 
If just the throttle servo went crazy, switch the connectors for the throttle and steering servos, and see if the steering is now causing a problem. Don't start the engine, this is just a quick servo test.
