Speaking of accersories, why stop at 3rd channel? there are 4channel radios on the market now: Futaba 4PK and the Nomndio React and Sensor are all 4 channel.

I toyed with the idea of getting liek a 12ch plane/heli 2.4GHZ radio and using that to do dual stearing servos, front and rear brakes uisng brake mixing, a ch for remot kill switch, and the rest for all sorts of goodies: lights, working turn indicators, etc.

I figured that I would use 8 of those 12 channels for all this, but I can dream up other stuff to use the other 4 for
