Hi guys a couple of questions before I make a purchase.
I'll be running with 12 cells.

(picture of the truck that it will go in)

1. Which motor for this emaxx setup? 8,9,10?

2. I'll get mod1 pinions but how many teeth? I have a strobe slipper that I'll be using.

3. Will I be needing a UBEC?

4. What are my expected run times?

TIA
