Looks good!

Even though the tires are rated for 80 PSI what are you running them at?

How's your wheels holding up? I believe I have 30-40 psi in my T3's. After a few weeks of running and a full day of about 15 matches, I see a good amount of wear on 4 of our 6 wheels.

The Vines have been fine, we have been running them at 70psi on our practice bot, we didn't top them up during our two days of practice this weekend so they are probably lower then that now. We have enough for our practice bot and real robot, plus 4 spare Vines and more of the regular knobby AM style tires as well if we need them.

It was really great to see your robot up close on the weekend. I like how cleanly the intake mechanism is integrated into the overall design so that it performs multiple functions. The workmanship is also topnotch.

Thanks for hosting us on the weekend so that we could make some real progress before bag and tag and test our design on a field. Thanks also for your advice regarding how to make our bumper design legal.

We are looking forward to playing with you at Bayou and Lone Star.
