Ok i have a novak havoc pro esc in my blitz. i have it on a tekin 7.5t motor. a traxxas water proof servo and spektrum dx3r radio. when i run it pretty wide open it runs fine. but if i run it about half throttle around my drive way just barely going it stalls and shuts the esc off and then back on and runs but only does it at half throttle. wide open its fine. i checked the gear mesh and its not to tight its good. any ideas. im stumped. i run it on a fully charged 4000mah 2s 30c lipo also.
