3539 used a 6w WCD this year. The past two years, we used 8 wheel standard tank drive, but this year we tried WCD to open up the inside of our frame for our ground intake and we were EXTREMELY happy with the results. Our drivetrain was easy to build, easy to maintain, rugged, light, and extremely nimble. We had a 1/8" drop on the center wheel, direct driven from our gearboxes. Custom 6" aluminum wheels with roughtop tread. We were geared for about 13 fps, so we were able to drive around most other robots on the field. We were very satisfied with the WCD style and will likely be visiting it in the future.
Here's a little video of our robot driving around at Troy. It was fun to watch this thing go
