Nice looking conversion, I am sure that it is better now for racing purposes. I still prefer my LS10, but it is a basher and lacks the center diff of the crt.5. I agree with brian on the higher voltage issues. How about running a 4s1p pack on a lower wind l motor? Those 2200 cells are good for 40 or so amps and that would be fine for a 11 or 12l can motor. Or even a low wind s can?! Not sure if the run time would be comparable. Or go with a lehner 1920/30 or neu1506 with a similar kv to the mm motor, would be cooler running and maybe scratch out a few more minutes out of that 4200 pack. The maxamps 2200 cells are good, I have a few 3s packs and they have been used in most of my rc collection!
