Here's version 2 that incorporates AustinSchuh's advice and adds other improvements including:
-Easily removable gearbox connected via gear to the axle (like 971's recent robots). Increases belly pan space and simplifies belt mounting.
-Outer wheel bearings are in sliding blocks tensioned with cams, allowing for better belt performance.
-WCD-style pulley mounting allows for belt changes without removing wheels.
-1.8lbs lighter
 
Closeup of cam and bearing block. There's an identical block and cam on the outside. Anyone see problems with this setup?
