Dang... Ben has a good eye. Yes, there is a 2nd cylinder for a brake in there. We figure that we either don't want to get pushed around or we don't want to roll off ramps. No stage diving for this rack star!

The drive base is somewhat modular. The guts of the drive module in the middle is an AM Shifter. We removed the sprockets, and added a gear and another reduction to the shaft that drives the middle wheel. Essentially, it's a direct-drive AM Shifter.

On the ends are wheel modules. These simply hold an axle for the outside wheels of the 6wd. Chains from the drive module axle power the axles on the wheel modules. We've got a neat-o sprocket/hub that works very well for this.

Since we have these "modules"... we have some options. We really like the 6wd setup, but if we had to do something else, we could.
