It is now stuck in wot with the radio on and will not slow down or speed up with any brake or throttle input. I'm a bit frustrated because I spent $500 at my lhs on electronics, battery, and charger and they weren't able to give me much help with it.
seen this a few times.
First have your car turned off
Set your radio EPA at the defaults which I am thinking will be 100 for THrottle EPA and throttle trim at zero. Have brake the same way.
Have the car on a surface so its up in the air, wheels can't touch the ground.
While hotting the set button on the ESC down, turn the esc on and keep holding that set button down till it starts beeping.
Once it does that, you should be able to program it. I don't recall off the top of my head all the steps but it should be in the manual (its something like Neutral, FWD, BRK. Or Neutral, BRK, FWD).
If you find it has trouble setting BRK or FWD, try reversing the throttle channel on your radio and then do setup again.
