Hey Guys,
Finished upgrading my downhill e-beast.
I've got a big 9.2kg hub motor on a 24" wheel along with 21S LiPo and a 45A Greentime controller with the shunt soldered to the point I'm drawing about 100A (yeah it will explode soon I know...)
Well, first test on full charge, leaning on the handlebar to keep the front on the ground and of I go to pull full (scary as f***) throttle and suddenly I hear the motor stuttering with a fast "grr grr grr" sound each time I accelerate hard (doesn't happen while just riding fast).
* Hub is brand new and runs cool like the weather outside, even the cable is barely slightly warm.
What could it be?
