[Monkey]

Ok in 90% sure my ESC is dead but just post what happening for some confimation before i start hitting it with a hammer its a 2099 it was driving round the track and it stopped dead :032: upon closer inspection the pinion jusent turn when you squeze the trigger to about half throttle it bleeps in like a pattern bleep bleep bleep BLEEP or something like that if you go full throttle th pinion jerks vilontley but dosent turn the when its unpluged the pinion spins freeley so the motor isnt jammed any body think of anything i could try before i order a new ESC?
