Got it all in. you were right, it was extremely simple. the hardest part was making an ESC Mount. I will put up pictures later. I used bulletproof glass to make the ESC mount and battery tray.

With a 48 tooth spur, what pinion should I run? I am running 4s on a 2200. I don't want to be geared high for sop speed, but I don't want it to be slower than nitros on the back straight. I have a 13t and a 16t. What would be best?

i was gonna say 15, but try the 16. i run a 13 on 6S on my track and it's very controllable.

you don't think that will be too hard on the ESC or batteries? Would 13 be chronically undergeared?

not for 6S. 4s, 15 or 16 is good.

ok, well, I am running 4s, so I figure I should run a 14 or 15. Guess i will just run the 16 and keep an eye on temps.

The losi 1.0 diffs and 2.0 diffs are the same, typically stick w/ the stock diffs until you need a rebuild then just use the heavy duty diff cups when it's time to rebuild... There is no reason to pull prior iMO, I raced weekly w/ the stockers w/o ANY issues.
