I suppose I can, though I'll have to find some efficient way of doing so.

Austin -- I appreciate all of your feedback and will address it as well as I can tomorrow. It's late now.

I like the concept a lot!

Dead axles everywhere. I'm using McMaster-Carr part no. 91780A901 for the axles. I'd use round standoffs here to save a bit of money / frustration with the hex bearings if I could, but the COTS hex standoffs are more readily available and cheaper than anything round at that length.
The wheels are VexPro Versawheels with 3/8" hex bearings coupled to 64 tooth, 1/2" hex bore gears. The 1/2" hex bore clears the 3/8" dead axle hex. We've run this arrangement a few times.
The idler gears are 35 tooth AM shifter gears and are designed to have a bearing pressed in. Here, we'd like to use the WCP equivalent gears in aluminum.

Knee-jerk reaction.

Given the same conditions we had in the 2013 season, this frame would fair only a little better. The biggest problem we faced (outside of our frisbee systems being garbage) was that we couldn't get any sheet metal parts beyond the frame made in our build window and the finished frame was missing the belly pan. I expected that'd give it a lot of rigidity and, in its absence, the entire machine was too flexible.
In the end, if it is feasible, we're happy to avoid chain. Even when it's working (95% of the time for us), it's still a pain the butt to get it installed and tensioned properly.
