RE: Ni-Cads & Brushless motors ????
as mentioned before you MUST have a BL ESC to run a DC motor, all the "magic" happens in the ESC, a non-sensored BL motor is just a bunch of magnets and bundled wire, the esc has to pulse the coils to attract and repulse the magnets, a houshold fan motor is almost wired the same as a RC motor, only the AC 60Hz pulse from the powerlines acts as a esc, you run a fan on 120V DC, expect a fire! (with acception of a few really old AC/DC fans (band pun) that operate like a starter motor (without the solinoid)
