Re: [TCML] ARSG question
I have nothing useful to say here except that would be awesome if it
worked!!! My biggest concern would be the RC receiver, I know dimmer
switches don't work well, and sufficient shielding would surely block the
signal from the remote. If you have an RC car I would suggest you just try
running it near an active coil in a little Faraday cage and see if it
works, I do also know those motors are designed for speed and not torque,
so your rotor would have to be really light (but with those RPMs you'd have
to be a fool to not want to go propeller style anyway, simplest mechanical
gap construction ever!) Let us know how it goes, hopefully someone else
