That hurts their pushing power. 100*1.3 is equivalent to 150*.867, about the amount of traction advantage a full-weighted 4ft class robot would have with something even less grippy than the old wheelchair wheels that were in the kit. They have the torque, and they have the treads, but they are lacking the weight.

Do the old wheelchair wheels realyl have that much traction? The new AM wheels are 1.0-1.1 and they seem to have a lot more traction than the skyways...
And to contribute to the post; At LA we ran two small CIMs on each side to 1.2 cof wheels in a 6 wheel drive. We weren't traction limited and had a 9-10 fps top speed. For San Diego, we are probably switching to a small CIM, a large and a FP (modularity and CNCs = awesome) which will give us the same speed, but we will be traction limited so we we'll be able to push a lot better.
