I recently bought a gymkhana fiesta brushed and it has not wanted to steer since I got it. I have put three new servos in it and nothing. I tried reprogramming it and it starttes steering but it is jerky and seems to want to accelreate randomly. I am scratching my head here, I wondered if anyone had any ideas or if since it has done it out of the box it is going to have to take a trip to traxxas to be repaired.
