I need help =(

[Tom F]

My Hacker controller has been acting up on my.

I've been trying to run a 7 cell GP3300 pack on it which arrived this morning.

The pack charged to 10.6V which seems reasonable enough, but in the truck, there's just no real punch there - and it's not all that fast.

I've tried everything i can think of - gearing, timing, endpoints...

I was also getting some horrible glitching on the throttle from the speed controller (the steering was fine and i'm using an FM radio)

Out of ideas. :mad:1

Help?
