I think 6SA123 is too much for the 8XL, its doable but will run hot. I'd go to a 9XL or even 10XL for more reliability.

The only challenge using the CF chassis on a conversion is that it can't be bent, and I'm not sure how easy it is to drill and mount screws into. You'll have to carefully consider how you will mount batts if you go this route.

You'll prolly want a Q125 heatsink as well.

Gearing? I'm running around 16.3:1 using 8XL/4S, but its not set in stone yet. The Revo tranny is pretty adj between the spurs and 2nd gear. Use Brian's calc to try out the gearing combos.
