The Blade Controller is used to attach Blades to a propeller bearing (Jury-Rigged or Brass) and to control their blade angle. Each blade controller can hold up to a maximum of eight blades (or wide blades); the more blades you use, the greater the force the propeller generates, at the cost of requiring higher SU in order to function. The blade angle can be set by holding down right click when prompted on the front of the blade controller. The angle must be set higher than zero for the propeller to function, and higher blade angles also increase both force and SU.

Usage
When filled with at least one Blade and attached to a rotating Propeller Bearing, a Blade Controller will generate thrust, which can be used to propel planes, airships, and other vehicles forward. When the bearing’s 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. Wide blades may also be used to produce even more thrust at the cost of even more SU.
Blade Controllers are not used when building a propeller using sails. The sails should instead be directly attached to a Brass Propeller Bearing.
