I've been meaning to CAD a polycarbonate drivetrain lately. You might see it in a few days.

One word of warning on the PC drivetrain is that because of the elastic deflection, large hits have a tendency to throw the chain if you're not careful with your construction. This was a serious problem on our 2003 and 2006 robots (mentioned above). Our 2006 drive team considered it a miracle if the robot made it through a match with all the chains still on.
