glitching throttle servo
 

my setup:
radio: Futaba 2PL
servos: S3003 throttle, and hi-torq futaba steering
Battery pack: 5 AAA cell Ni-MH
Car: HPI R40

hey guys,

i was out running on a track i set up with my brother this morning ... and for some reason my throttle servo was glitching hardcore, like it wouldnt open the carb till my trigger was pulled back about 1/4 to 1/2 the way back, then the car would start going some where.. my pack is fully charged... has any one had this problem before??? is it a simple fix?? i got a futaba S3003 i belive... could it be my radio ???

Thanks
