I knew I didn't need a 2" cylinder, but it was the smallest I was able to find that would work when I posted. But speak and it shall be so. I went back and checked, and this time I found the 1.5" pancake cylinder. I will probably end up using that one.

This would also make high-speed mecanum your "default" drive if the pressure goes out, which may be a good or bad thing depending on your game strategy/style.

One of the big perks of octocanum for me is built-in mecanum suspension. I wanted to pivot on the traction wheel so we wouldn't have to worry about uneven loading. I agree that switching them would make it easy to do a dead axle, but that would take away a major advantage in my opinion. Would it be advantageous to add more bolts, a piece of churro, or some other cross brace between the wheels to better connect the plates instead of going to dead axle?
