This year, we tied some into a loop, and use it like a big rubber band to power the kicker. A pneumatic piston pulls the kicker back for another shot.
Does your piston move during the shot? Most video examples I've seen of various pneumatic/tubing kickers show the piston moving during the shot.
If your piston moves during the shot, does it move faster than 20 inches per second?

Has Bimba (or any other actuator expert) sanctioned any conditions where a piston is "engineered appropriately" to move the piston faster than 20 inches per second?
