2.4g question
 

ok my latest purchase isint a savage, its not even a hpi but im on here all the time and thought i would put it out here. Ok its my first 2.4 system its an ace rc it doesnt have a built in failsafe so i added 1 but sometimes with it installed nothing works and the next time it does, i mean nothing at all including the steering works, i wouldnt have thought it would have made a difference but does it?
