The "All-in-One" Coaxial Helicopter Flight Control relates to a mechanical control mixer system integrating all the controlling input orders of the pilot to control the flight patterns of a coaxial rotor helicopter.

In particular by controlling the degrees of pitch changes of a coaxial rotor device:

- Collective Pitch
- Cyclic Pitch
- Differential Pitch

These controlling inputs are transmitted in equal and simultaneous values on the two counter-rotating rotors.

Diagrams below shows the entire coaxial swashplate control link couplings. As seen, the "All-in-One" system is coupled and installed under the gearbox of the Coaxial Drive System (CDS).

Advantages of this "All-in-One" System:

- Very compact
- All links are straightforward & redundant for security
- High precision input order transmissions
- No parasite effects in control orders mixing
- Built-in automatic throttle compensation maintaining constant rotor RPM for Collective control
- Built-in automatic collective pitch compensation maintaining constant altitude level for Yaw control
