Large Rotor

The large rotor is the largest traditional helicopter main rotor included in Stormworks: Build and Rescue. It is usually served by a gyro to help keep your aircraft stable, and requires power from an engine. 
When placing the large rotor you have an option to use positive or neutral rotor pitch. Neutral pitch is used when you want to use the rotor's collective control to ascend and descend. If you configure your rotor blades to be positive pitched, the amount of upwards force generated by the blades is always directly proportional to their rotation speed.
