Hopefully this year's drive train will be better.

Sure i could slow the bot down in software but that would sacrafice torque and would require a nasty algorithm so i could still output the necessary horsepower when steering.

I would *really* like to see this year's drivetrain use more standard parts.

Why not use a larger sprocket on the wheel itself? (Or did you have a clearance issue with the outside diameter?) Other options include adding a second shaft with a large sprocket (for a large ratio) somewhere out of the way, and then chaining that to your wheels with a separate length of chain. In any event, the kit sprockets have a standard #35 ANSI power transmission chain tooth form; it's only the bore that is custom.
