We made a second robot after the ship and before competition. It was wonderful for driving but actually it was what did us in eventually.

1) We lightened it. Our wheel mounts held up wonderfully on the practice robot and taught our driver to not be afraid to hit the controls. Then we got to competition and high acceleration bent the lightened mounts very badly

2) We painted it. The wheels on our robot can slide backwards about 2 inches for chain tensioning. The bolts hold the wheel in place with friction but on the painted frame the bolts slid.

So yeah...lessoned learned...test under actual conditions.
I hate it when common sense is right. It gets in the way of the math.
