one of the teeth for the throttle/brake broke and caused the buggy to be stuck in the full throttle position.
why is it whenever there is a throttle problem or servo, or carb stuck or battery fell out, its always at wot? come to think of it its never happened to me where a servo dies or battery fell out in the middle of braking. well, once my reciever died after a jump and the buggy just sat there, so ok, 1 time, but all the others it was WOT!! things that make you go hmmm...
