I have spent many hours rebuilding my emaxx and decided to take it out on its first new run and the wheels will not turn when it is on the ground. If I pick it up the wheels will turn, so i swapped out the servos and still nothing. I am at my wits end trying to figure out what is going on. I know for a fact that 1 of my servos is brand new, the other I robbed off my Rustler just to test. Any ideas or pointers would be greatly appreciated.
