Ahh, yes I remember the problems you had last year (I machined some replacement parts for them at BattleCry. Are you shifting with them, or do you just leave them in one gear?

We originally planned to shift between 1st gear (for traction and grip) and then use 2nd gear for driving around and avoiding. But as we were practicing at our shop we found that while at first it seems hard to control, with time we could just use 2nd and tear up the field, and that some tire spin would be helpful for doing some trick turning. The problem we had with them last year was we skimped on the axels to keep our robot weight at 90 pounds, so if in autonomous we crashed into something they would bend and break and lead to issues. This year we used stronger ones and made about 4 spare sets to just pop in and be ready to go in minutes. We're considering using 3rd gear for Philly to see if we can let us drive away faster from robots out to pin us.

I just made a compilation of our robot in action at the Boston Regional.
Hope you enjoy it!
