Question
Hey Matt C,
I have tuned up the th trim on my controller and the car is stationary, it accelerates sometimes.

It sometimes stops and starts twitching and then conks out?
Would this be the battery or another problem?
Thanks Michael

Answer
Hey,

It sounds like you are getting some interference from something else or the batteries in the transmitter are low. The broken antenna could cause that if it's very damaged, also. If your car is not receiving a good signal from your transmitter, it basically responds to any other stray signal in the air which can cause the twitching or unpredictable actions.

Matt
