the pinion is a 18 (maybe a 20) on the OFNA 51T strobe slipper - this is what Mike suggested. Stock diffs/Trans, MIP CVDs. There is less cogging in low gear.

I have'nt put it in the dirt yet, I am hoping it doesn't effect the climbing at low speeds.

I have read opinions on how the UBEC should be mounted ( ex. flat side facing electronics), is there a preference?

What are the max cells for a 12020/8xl?

You guys are awesome!
