It looks very slick! The frame resembles the one we used last year, and it held up well. If you use bumpers wisely, it would even be possible to cut some of your 1/8" pieces down to 1/16".

My only concern is the way you're mounting your modules. If you get a sold hit from the side, while your wheels are pointed forwards, the load on the shafts are INSANE (you have done crab for 4+ years, you know this =P). If that is a solid block of aluminum (eek! heavy) I'm sure it would be able to hold up. However, no matter how you attach that block to your frame, that will be the weak point. The 1/8" wall of the 2" x 1" box it's attached to does not seem like it would be able to withstand such loads (especially at the points where it's connected). If you use rivets, it's very likely (guaranteed) that they will fail. Maybe consider trying to add support on both sides of your mounting block.

Overall, it's very scary. I know you guys have plenty of crab experience, so I know you'll be able to pull this off exceptionally well. Good luck!
