Good catch! thanks, I will let the mechanical team know about this and we will figure something out.

We can easily change the wheels out, we would rather learn and see the differences ourselves to make our own decision. But thanks for raising that point.

If you look at the Duluth East Daredevil's robot from last year, we mounted most electronics on the vertically on the battery stack. Have you considered doing that? It might save some bellypan space, depending on what you want to use the robot for in the long term.

If you switch the pinions on the cims to the 11t pinions that Vex offers, your free speed goes down to 23fps, which is still extremely fast. Then switching to 3.25" Versawheel DTs with the pinions is 18.8fps. Going to 3" colsons with the 11t pinions gets you to 17.4fps free speed, which although fast is still ok for a 4-cim drive.
