The tail rotor on conventional helicopters generates a counter-torque to the main rotor. The coaxial main rotor concept of the CoAX 600 makes the tail rotor superfluous and eliminates the need for the pilot to control this disruptive force. This results in easier operation of the aircraft. At the same time, a significant source of danger is eliminated, which can lead to very serious injuries in the event of inattention.

The CoAX 600 also simply does not have a serious tail rotor failure scenario during flight. The lack of a tail rotor significantly increases operational safety on the ground and in flight. The entire engine power is available to drive the main rotor, as no power is required from the tail rotor. The main rotor therefore generates significantly more lift than conventional helicopters with the same engine power. The performance of the CoAX 600 is correspondingly high for this reason.

The rotor planes are designed as a teetering configuration, also known as a seasaw rotor. They are characterised by two opposite rotor blades with the same cone angle and a common, central flapping joint. As a result, the joint flapping of the two rotor blades in opposite directions minimises variations in the centre of gravity on the rotor blade orbit and results in lower loads for the rotor blades and rotor mast. This significantly increases the service life of the load-bearing structure.

The autorotation characteristics are also favoured by the coaxial main rotor. Due to the use of 2 x 2 rotor blades, the stored energy content of the main rotor is significantly higher than in comparable conventional helicopters. This extra energy gives the pilot greater room to manoeuvre in autorotation mode. Rotor masts.
