I've used this same 1509/2Y/F in my crt.5 on 5S as well and it's a great motor for the application. You can gear to ~40mph and it'll run super smooth with the option to easily gear up to ~50mph for some high speed insanity.

Even on a MM with punch at 40-50% it'll near rip the tires off the wheels if you want it to.
