Setup Help
 

I just finished intalling a brushless setup on an e-maxx and it is not functioning properly. When I gradually pull the throttle the tires spin but if I gun it, it totally dies. I believe I have everything programmed and wired right. It just stutters and I have no idea what it is.

BK 1920 controller (black jumper removed)
Feigao 8xl
external ubec
8-cell IB 4200 in series
strobe slipper
and several more....

Well I found out it was the UBEC that was causing the problems so I switched to a receiver pack. But right after that one of my battery packs leaked acid and died! Does this have anything to do with my setup or just a bad pack?

i would think that it is just a bad cell
