About Gyroplanes otor port uk R S Home Support Contact Site map How do they fly?  They may look like little helicopters but the rotors are not power driven.  Lift for any aircraft depends on two factors - wing area and wing speed through the air.  Fixed wings have a large surface area but fly relatively slowly. Gyroplane rotors have a small surface area but spin quickly generating high speed and lift.  The gyro is driven forwards by the propeller, forcing air through the rotors causing them to spin - rather like a child’s toy windmill.
