The other end of the cylinder has no fitting and vents to atmosphere.
The interesting side effect is that we are able to fire the valves 1 or 2 or 3 at a time in order to control the kick distance (scoring, passing, or over the bump). Now it's up to the drivers to remember which button to push!
Good luck!  |
i love that idea cus we're using the horizontal and the ball is moving to sluggish to do anything with it. can u post a picture of you pendulum?
