throttle issue

[ReDrUm_Racer]

well today i was driving my brushless hyper 7 and it was running like a champ. I started driving it up a hill and when i stopped and tried to reverse, the throttle did not respond. I walked over and looked at it, and all the connections were fine, but the throttle did not work anymore. The steering still works fine, so I know at least the bec works. I checked over the motor connections, they seem fine, the rx connection is fine, and the batteries obviously are fine because the steering works. Btw I'm using the integrated bec in a 9918. Any help would be great!
