And yes, they look very nice. How many times (if any) did you have to replace the FP motors?
Once.... because someone pulled the power lead off the back. We never burned out a FP though, even though we were playing rather rough with them.

The spur gears are from andymark, so that is a 14:50 from the small CIm (28:50 for the big). The 10 tooth sprocket drives a 42 tooth on a 6" wheel. It was actually closer to 9 fps if i remember right.

As for the weight, it was about as low as it could get, I don't have the official weight, but I know the mounting plate is about .4 lbs... So that, plus the three motors and gears makes up the weight. The other plate would be a frame member so that doesn't count i guess. Without motors, they are about the lightest I have seen (the 50 tooth gears were later spoked and hogged out to save some weight there as well) besides Travis Covington's amazing creation.

When I get home from work tonight I'll check the CAD models and get a weight.
