I have a xerun justock that I purchased from my lhs. I ran it through a few packs without calibrating it to my radio and noticed top end was lacking a little. I went to calibrate it to the radio(airtronics m8) epa set at 100 and trim set at 0 and once I did the car just shot off like a bottle rocket. 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.
