Cyclogyro & Voith-Schneider Mechanism

This Cyclocopter rotor has the ability to quickly redirect thrust vector in any direction normal to its axis of rotation via rotating the central hub
independently from rotor rotation, it can also vary the magnitude of that thrust in any direction by changing the eccentricity of the pitching hub
using the small partial gear protruding from the central hub. That's why cyclocopters have remarkable maneuverability.
