Interestingly you 2 have quite similar robots in design but have taken 2 very different approaches to making them.

Ellis, you have taken a more 'Bitza' approach of using existing materials, blood, sweat, tears and hope!

Alex on the other hand has carefully designed in CAD, bought Li-Po's etc...

Apologies if I've got that all wrong! But there's nothing wrong with either approach, be interesting to see how they pit against each other. Personally I'd like to see them turn out quite equal.

As for the Gimson motors I believe they use Drill motors for power the hrs-550s (various voltages), they just have the massive added advantage of Metal gear boxes, supported shafts and decent mounting points.
