I get 3.86 and 9.86 ft/sec with no speed loss and 5310 CIM free speed, for reference.
The stages of reduction are:
12:40 CIM->cluster shaft
15:48 OR 28:35 cluster shaft->shift shaft
16:36 chain
It seems like a lot of chain reduction with 4" wheels. The ratio chosen seems to be perfect for 6" wheels (5.79 and 14.83 ft/sec with no speed loss, 4.69 and 12.01 with speed loss, 46 amp wall-push in low gear)

Well that seems kinda low. My 22 fps is definitely wrong, and I've unfortunately lost the paper I used to calculate it (off to clean my room now!).
Madison, is Apalrd right? This looks like one of the best kitbots I've seen, but 10 fps and 3 fps are not my cup of tea. :|
