When my throttle servo on my Nemesis burned it locked at full throttle and hit a curb and shot straight up in the air and landed on the roof and and the engine raced wide open. since it was dark I couldn't just reach in to pinch the fuel line, so it screamed until my wife got the flashlight, when she ran up with it the engine ran out of fuel in the line. The crazy part was there was NO damage(except the burnt servo, of course) and the engine fired right back up!!! The best RC vehicle I have ever owned!!!
