Thanks for the input, guys. I have a CC Phoenix 60A ESC at this point, which I guess would be adequate for now. I had just assumed the inrunners were easier to mount. See what I mean: if there's a pattern to the designation of each motor, I'm too dumb to see it!
Yup, all manuf. pretty much have their own numbering system. The only one that makes good sense to me is the RimFire - 42 is the dia. in mm - 60 is the length in mm - and 600 is the kv rating.
