That may be, but just in the nick of time, I've been offered some wheelchair motors, from a nearby mobility shop. Perfect. I don't know what they have in stock yet, but next time I pop up, they'll have something for me. Well, when we get a text through, that is.

So, step one done. Sort of.
Step two. I already have half a speed controller, can anyone tell me if I do actually need the £40 radio thingy from 4QD (I have the 4QD NCC) or if I can use the cheap, £8 same type of thing. Links below.

The expensivy one
The cheapo one (at the very bottom of the page, I assume the second board would work)

Thanks for any help.
