Hi Jeremiah.
The mechcanial team says it can lift around 500 lbs. 480 lbs to be exact. It uses two air cylinders, and two gas springs with a 100 lbs rating. We use compressed air to compress the gas shocks down, and hold them down.
The lifting after power is cut is EASY....we use a double soleniod valve. The SMC one comes in the KOP. When the spool shifts in a double soleniod valve, the air changes state and keeps on lifting even after the electrical is cut from the soleniod on a double valve.
We used chrome moly tubing that was welded by a student and a mentor. It's the same tubing they build landing gears for airplanes and race care chassis. It's very strong. The whole frame only weighs I think around 34 lbs if I remember right. Each wing is moncoque and weighs about 11 lbs or so I think. I can't quite remember what the mechcanial team said so don't quote me on it.
