Piston

The piston is a block in plane crazy and can be used for many purposes. It's main purpose is to push other blocks up to a length of 4. The piston must not be touching other blocks. For example, say you have a jet and you want the cockpit to open. You can use 2 things. Piston or motor. (another page by me soon) The piston can't be touching the sides of the plane or it will not work.
