My biggest complaint about the kit is the lack of chain. After making the drive train they described in the Module, I had about 5 links of chain left over. I might be able to put it to 25, 30 links if I move the wheels really close to the motor shaft, but still, thats not enough to even hook up a third wheel. How expensive is it to make a plastic chain? The InnovationFIRST site says 6 bucks for a foot, but I'm sure you could make it cheaper. On the other hand, how easy is it to find a chain that fits? I definately think they should have included more chain or found a way to produce it cheaper.
