Sorry, been a bit busy lately so just getting time to answer questions.
There are two 1.5"D x 8"S cylinders and two 3/4"D x 1"S cylinders. We went for less of an "design for optimal" plan this year and more of a "what do we have a bunch of in the pneumatics parts tub" plan this year. Money is always a concern...
The large cylinder on the top stretches a black tarp strap a variable amount depending on the pressure used which gives us more or less kick. The large cylinder in the middle cocks the arm and once locked reverses pressure to add to the kick. The two small cylinders at the bottom trigger the release.
The number of kicks varies depending on the pressure we use for a particular distance.
Ball possession in front of the kicker is still in development...
