Unlike the Propeller Bearings, the Copter Bearing is gyroscopic, meaning that it will always try to maintain the orientation in which it was placed. It may be used in any orientation, though is often used vertically for helicopters and other similar vehicles. The Copter Bearing is currently a WIP and does not have a recipe.
Obtaining
No survival-friendly method (WIP).
Usage
When the Copter Bearing is powered with Rotational Force and has at least one block connected to it, right clicking it will start its rotation. If a Blade Controller with suitable Blades or sails of a suitable sides are attached to it, it will generate thrust, which can be used to propel planes, airships, and other vehicles in the direction it is oriented in. When its rotation is inverted, it will instead propel the vehicle in the opposite direction. The more blades are attached to its blade controller, the higher the thrust it produces, but it will draw more Stress Units in turn. The Copter Bearing is gyroscopic and will always attempt to maintain the orientation in which it was placed.
Copter Bearings are currently a Work in Progress. Use with sails is particularly unstable.
