No, the 430XL is called a "Canned" Outrunner (as well as all the Align motors for helis). It's constructed the same as other outrunners, except it has an added shell to cover the spinning rotor.

P.S. Nice Job HFG. When I have a chance, I'll o-scope out different motors and ESCs and see if there are any differences in the waveforms. I think on some, the PWM will be a varying PWM so that the "average" voltage will be like a sine wave.
