I had replaced the motor and speed controller after some advice I got from this forums and some other places. I have two issues now.

1: When I power on the truck a light on the speed controller blinks and the front wheels turn jerkily to the right until they can't turn anymore. This happens automatically. The controller is off and has no batteries, so that's not the problem.

2: The controller doesn't work. The reason I know the controller doesn't work is because I took the truck to a hobby shop and they were able to get it running with their controller. I want to buy a new controller and radio crystals (right terms?) for less than $100. So I need some recommendations in this area.

I need advice and help. Thanks.
