[Mk.32]

One piece of advice to your team, your kit wheels in the back seemed to be slipping a lot on the carpet, especially when you turned. Best advice for that is to invest in some High-Traction wheels ("Plaction Wheels," available at http://www.andymark.com/category-s/103.htm )

Yeah we are having some problem with getting enough traction on the back wheels. We heard of a trick of just putting tread on the kit wheels with wood screws, so we will probably try that. But definitely will check out some newer wheels.

Very interesting lift! Any details/pictures?

I will get some decent photos next meeting. But the 2 stage lift is simply two pieces melamine inside metal holders. The melamine pieces are joined together with a strap. Then a 2x24inch pneumatic cylinder provides the force to lift the whole assembly up. It takes about 3 secs, for it to fully extend. And we have a center locking solenoid set up to allow us to pause it anywhere.
