On the Auto-Collective by Torque Pitch; the bottom of the pitch arms are mounted to the electro-rotor. Therefore any change in the rotational relationship between the aero-rotor and the electro-rotor will result in an equal pitch change in the 3 blades. In other words; more torque from the motor combined with more drag from the rotor blades means a greater blade pitch angle

On the Unique-Collective by Torque Pitch Coupling; the bottom of each of the three pitch arm has a magnet. In front of these three magnets is another magnet that is attached to the aero-rotor. Behind each of these magnets in the pitch arm is a third magnet that is attached to the electro-rotor. There is a repelling for between all three magnets at each blade. In this rotor any change in the rotational relationship between the aero-rotor and the electro-rotor will result in a pitch change in the 3 blades that is half the linear amount as the change between the magnets on the two rotors. In other words; the magnet on the bottom of the pitch arm will want to position itself an equidistant between the magnet on the electro-rotor and the magnet on the aero-rotor.

In addition, there is an aerodynamic moment acting on the blades. This moment varies with the amount of drag that each of the three blades experiences. Therefore, in forward flight the advancing blade will be experiencing more drag than the retreating blade. The pitches of the three blades are independent of each other, therefore the blades will have a higher pitch when they are on the retreating side and hopefully this will result in a more even distribution of thrust about the disk area.
