Propellor Bearing
The Propeller Bearing is a block that is used as a source of propulsion by attaching Windmill Sails to it, similar to Create's Windmill Bearing. It will generate more force depending on the amount of Rotational Force applied to it and the amount of Windmill Sails attached. Negative Rotational Force will cause it to apply force in the opposite direction. The Propeller Bearing can be activated and deactivated by right clicking it.
