I'll try that then, we have a massive amount of bike tyres in the shed, so that's good. So far I've got a definite list of parts, all I need now is a safety switch which I understand already, and a RC motherboard which I'm slightly baffled by! More questions! (no surprise)
I have no idea what sort of interface I should be looking for, and what is a BEC? I looked it up but I don't think it's a big english cheese...
