I agree to rapidrory on the motors and about the transmitter. Sometimes u can find deals where u get 2-3 servos with the transmitter / reciever combo and they might be hackable aswell.
Motors are more reliable than modifying the servos and at that cost its a great deal.
I've started ordering more and more stuff from china as most top rated sellers have free postage, it usually takes 4-7 days but can take 2-3 weeks if unlucky.
Mm, ok. I'll have to look into the modules then. Though I think homemade transmitters are legal if you stick to the regulations - found something I think is relevant here (not sure, mind), under exemptions - http://stakeholders.ofcom.org.uk/enf...nforcement/law
Are motors easier/cheaper to use than servos? I thought servos were meant to be easier, but from what I've read so far they're actually a bit more complicated? Especially as they may need modifying just to work!
