Hmmm.... I don't think going more than 6 cells with a 35turn motor (S0-3) is a good idea. 12V should be less damaging to a motor with a lower current draw.

Connecting the source directly to the battery also allows you to mod it such that only 4 cells go to the board (and light kit too?) while all 6 cells (or whatever number within the FETs' limit) go to...

Thanks 3ST. That explains why you love the Mini-X so much while I initially hated it.
I'm gonna get the rolling chassis and rediscover the experience. :)

Many thanks. That helped a lot. i'm still confused as to why no P-channel FETs are needed, but that is not important since I now know that they are both N channel MOSFETs.
