The car even took off on it's own a few times and ran into the wall or off the track.

The problem was the cheap turnigy servo I was using. I swapped it out for a hitec one I had laying in my box and all the issues went away! Everything was really smooth and responsive the way it's supposed to be.

I know I read a few people were having similar issues. This is want fixed mine.
