CN Spinner with diameter 30 mm was designed for inrunner motors, which are fixed on the frame in the traditional way (by front side of a motor).
Diametr motor shaft or hole in the collet = 5 mm; distance between the axes of the blades = 28.5 mm the blade tilt angle = 0.
The aluminum hub with replaceable collet is developed for pilots, who want to take full advantage of the capabilities of his glider.
The construction is light and strong. The existence of collet will allow to use the same spinner for the motors with different diameters of shafts.
You can easily and quickly replace both the blades on the CN Spinner or the entire spiner if the weather changes.
The hub and collet are made by milling of aluminum with further anodizing.
The shape of the hub will allow to fold the blades closer to the fuselage for drag reduction when gliding.
The shockproof cone is cast in glass-nylon composite.
