Thanks for the responses guys. I suppose until I actually get them in front of me itll all be a bit unclear. I had been considering the electronize speed controllers anyway but had absolutely no experince on the at all.

On the speed controller, there are two types. One with a 5v output for the receiver and one without. Any opinions on these?

As far as the motors are concerned, there is a massive variety of motors and gear boxes available, many different gear box ratios and so on.

Maplins do a range of the combo drills motors. Any ideas what sort of speed (rpm) they should be doing?

Gary said that a range of wheels and ready made mounts were available from members of the forum. If anyone wants to stick their hands up and tell me who they are, we can sort it out.

Thanks again for the help so far

Regards

Andy
