OK, I'm ready to order a motor. Gotta do it. The conversion is keeping me up at night. Just take a look at the time stamp on this post. :)

I just want to make sure that I have things right. I was considering either the 10L or the 7XL. If I go with the 7XL, I'll be rewarded with cooler temps and longer runtimes, is that right? I'll be running on 4S lipo. BTW, what sort of runtimes do you think I'll get on 4Ah 4S packs?

As I said, I'll be running this in an 1/8 scale buggy. It has a stock 46t spur. What pinion should I get? The longest straight on my track is 160' long and I want to keep up with (preferably pass) a nitro buggy with a Novarossi 21-5 on it. I'm figuring that I should gear for about 40 mph, maybe a tad bit more.

And...does anyone know how to harden a mod 1 pinion. RC Monster is out of the hardened pinions and I can't wait.
