b) Do you only use the support from the bearings in the gearbox or do you add additional support?
3) Is there a set wheel width that you use? (narrower to be able to move the gearbox outward further? ie 1" traction vs a 2" traction?)
4) How much drop do you use for the center wheel?
Thanks! I'm sure as we look into it, I'll have more detailed questions!!

In 2013 3309 used a WCD.
1) snap ring on the outside and the wheel hub was made to touch only the inner ring of the bearing.
2) used a custom gear box but the COTS options are very good.
3)Used Colsons that year, we plan our wheels to be traction limited in low gear. We were geared a little to high so we never added grooves to the colsons or switched nitrile rough top tread.
4) It was 0.125, it worked but was a bit too much. I would not complain if I had to use .125 but if I could get 0.100 I would go for it.
This year my team used octonum which was harder to change wheels. So the biggest thing we noticed was that if you have a practice bot and drive more than 10 hours a week. Wheel changing becomes very important. So next year 3309 is going back to west coast drive. Especially comparing our practice time to elite teams, we need to up our game. We are targeting 20 hours a week (including autonomous work). We are also hoping to practice against more orange county teams next year, so wheel wear will be very high. So changing wheels quickly is a major concern for us.
