Pneumatics trade at Nats

Subsequently, we witnessed several teams play with zip ties on their wheels so i guess its back to legal.

We have the problem of too much traction. At the Chesapeake regional we spent 20 minutes putting zip ties on the wheels to reduce the sideways traction. Then we took it to inspection, where one of the inspectors said zip ties tear up the carpet and made us spend another 20 minutes taking them all off. Frustrating.

We have some medium bore, 2 or 3 in. stroke cylinders from the first year our team was competing. They are past pneumatics so they should be ok. They are SMC and they have the thread on the rear of the cylinder. You could drill a big hole in something and just attach the back of the cylinder to it. They still work fine (we used them for the pneumatic mock-up this year).
