I sized my mx400 motor last night as well, I agree it will drop right in, what about the gear, what are you going to use for that?
you had to throw a snag into my evil little plan didn't you? hmmmm..
I was actually thinking (I didn't do much on the gear by the way) that I'd use the pinion from my MX for it, if that don't work, I'll use the stock pinion for the CP, when/if it flies then I'll start looking at number of teeth that I need to use...
