Product Description:

Airfoil and Blade Design

Blade design combines modern day Aeronautics and wing structure of a Falcon to create a remarkably dynamic and efficient air flow at every speed.

The blades use modern day Aeronautics principles to optimize air flow at every speed by dynamically and adequately adjusting the blade angles.

Blade Configurations:

Five Blade Configuration

Mounting Configuration:

The mounting hole pattern consists of a 76.2 mm square with four 3/8″ pem nuts at the four corners of the square. Two holes in the middle are meant for cable routing and are covered with a protective shroud
