Motor driven catapult gear ratio

DEKA is right next to the river, and when i got there this morning they wouldn't let us into the building, but apparently there is and standing water on the first floor. The ironic thing is that i work on the water project and we can't deal with a bit of water on the floor - Greg Needel [more]

The arms are made of thin walled 1 inch square aluminum tubing. After 80 shots there is no sign of any wear and tear on the arms. We used thick wall on our practice bot and noticed a substantial reduction in performance.

There are JVN style pegs to the back made of schedule 40 fiberglass tubing (PVC would work just as well). We are stilll determining the optimal lenth.
