CRT Brusless converison

[What's_nitro?]

Nice looking conversion, and welcome to RCM!

If it seems slow to you that's because it is. The Align motor (1700kV) and a 4s LiPo pack (~15V) only give you ~25000 max. RpM to play with. How are the temps after a run? You could try a larger pinion (say 15T) if nothing is getting very hot. Otherwise a new motor somewhere in the 2200-2500kV range would work, or moving up to a higher voltage pack (5s or 6s). The Align will handle up to 6s as will the ESC. The higher voltage option would be optimal since it will be more efficient. For a 6s pack a motor in the range of 1400-1600kV would be desired. I'm basing this on max. motor speed of 35000 RpM, which is similar to a nitro engine.
