Light and strong, CN-Universal F5J and F5K spinners are designed for in-runner motors.

CN-Universal F5J-F5K Spinners 30mm/5mm Hub

Light and strong, the CN-Universal F5J and F5K spinners are designed for in-runner motors that are bolted on the firewwall in the usual way. The special shape of the hub will allow for optimal folding of the blades closer to the fuselage for drag reduction when gliding. You'll get the best prop fit by using CN's spread tow propellors that are designed for their hubs. The hub and collet are made by CNC milling aluminum that is then anodized. The split collet reduces vibration and can be used on motor shafts without machined flats. The shockproof cone is cast in a glass-nylon composite.

You can easily and quickly replace both the blades on the CN-U Spinner or the entire spinner if the weather changes. Changing collet sizes will allow to use the same spinner for the motors with different diameter shafts.

Collet motor shaft diameters available: 3 mm, 3.17 mm, 4 mm, 5 mm, 6 mm. 

Distance between the axes of the blades = 28 mm

Blade tilt angle = 0
