Thanks for all the feedback so far!

Thanks for pointing this out. Originally we had one mounting plate that connected the swerve modules and the other plates. However, I didn't want to make the mounting plates without using CNC, and with our limited CNC ability, I thought it would just be easier to use the revolution mounting system. Thankfully we just got a sponsor with greater CNC ability so we'll look into that. How thick would you recomend making the mounting plate? 3/16 in or 1/4 in?

Regarding the gearing, we are using Toughbox Mini's with the 10:71 Gear reduction because they are going to come in the 2013 KOP. Along with the additional 2.25:1 reduction with the modules, with 4 in wheels its a little difficult to get a good gear ratio. As of now we have the reduction from gearbox to module at 1:2.4 letting our top speed without losses to be 8 fps. Is this fast enough? Or should we make it a bit faster?

Thanks for pointing this out. We'll try and adjust our design accordingly.

Thanks, we'll post a revised edition later.
