Yeah, I have said this before, but I would like to see AC induction systems for RC. Particularly, from Rasertech, they have an Induction motor tech. with same power density as these brushless motors, and same efficiency (but, better at partial load). I think overall they would be a much better system that BL power, reasons being:

-extremely durable (AFA heat, and no magnets)
-more resistant to shocks and vibration, and extremely high running temp able
-glass smooth torque under all loads/speeds (no torque ripple, or cogging)
-able to turn off magnetic field (BL is always on)
-much less expensive
-more control over motor power/excitation

To me, that makes a better motor.
