So, what are people using for motors/wheels/batts etc?
I guess I should probably experiment myself, seeing as with ants, feathers and heavies everyone pretty much knows the best parts to use whereas ideal components for this class have not yet emerged obviously. Will be interesting actually to see what motors, speedos and battery types come out as the best for cost/effectiveness to weight as machines develop.

I'm thinking of using this robot as a bit of inspiration:

and then scale it down and alter it a bit so I'm not completely stealing a design. I don't have the tools to custom make gearboxes to the degree of quality he does but I quite like the way it looks
