The 21-inch propeller is made of Ultra Carbon Pro, an advanced composite material, for lower rotational inertia in combination with high strength and stiffness. Their aerodynamic profile combined with optimized electro-magnetic design of the motor make the M600 extremely energy efficient.  These are the 2195 high-altitude propellors.
