4. Lowest Empty Weight:

The feature that makes the fuselage independent of the lifting system dynamics permits the design of the fuselage to be strictly functional as related to requirements. Accordingly, the size of the coaxial rotor system fuselage for the same useful load is smaller than any other type and structurally simpler, resulting in lower fuselage weight.

Consider these other weight savings:

1. The weight of the coaxial transmission system for a given horsepower is lighter than the total weight of the two or more transmissions systems utilized in either the anti-torque tail rotor or tandem rotor configurations.

2. The total blade area of the coaxial rotor is essentially equal to the blade areas of the main rotor of a comparable single rotor and is higher as compared to other multi-rotor high-disk loading systems.

3. The total weight of the fuselage, transmission, and rotor system of the coaxial rotor helicopter put together is lower than that of an equivalent engine horsepower of a tail rotor configuration and substantially lower than that of the tandem or other multi-rotor configurations.

5. Complete Symmetry of the Rotor System:

The symmetry of the Ezycopter's coaxial rotor system permits the same aerodynamic efficiency and controllability for flight in any direction; a feature only found in true coaxial helicopter with precision collective and cyclic controls.

6. Simplified Rotor System

The EzyCopter coaxial utilizes the semi-rigid type of rotor system without the need for use of mechanical stabilizing devices, thus resulting in a simpler rotor system design possessing excellent flying qualities. The simplicity of design yields benefits such as lower structural weight, manufacturing and maintenance costs. In addition, this rotor system makes the helicopter free from ground resonance.
