To answer the comments about 6wd vs 2wd:
This drive base design was meant to be simple and light. Part of meeting this goal meant not powering the corner wheels.
For 3 out of the past 4 years, 1519 has used a 2wd drive, powering the center wheels only.

We have had good success with this design. The only drawback of this drive system is, like IKE points out, it cant climb ramps.

I like 6wd, but this design is meant to be the simple, light, stick-with-what-we-know design.

I edited out a lot of your post, but I would like to challenge you that if you are spending the time to do an upfront design, figure out how to power at least 4 of those wheels. There are some extremely simple and cheap ways out there and then you will drive better and be able to climb ramps (or bumps).

We have excluded teams in the past (06, and 07) as picks for having only the center 2 wheels driven from our elimination selection list. If you need some pictures of how to get 2 more to drive, let me know and I will send them your way.
