The CN Models 25/3 Spinner is a great new spinner for small F5K class type electric gliders. It has a diameter of 25 mm and is suitable for motors with a 3 mm output shaft. The yoke/hub is beautifully CNC machined from aluminium alloy and anodised to increase the surface hardness and corrosion resistance. The black shock proof cone is molded from a glass/nylon composite.
The yoke has been designed to help ensure that the prop blades fold closer to the fuselage to minimise drag when gliding.
The spinner is attached to the shaft by a collet which is tightened using an allen key applied to the front of the assembly.
Motor shaft diameter = 3 mm
Spinner diameter = 25 mm
Distance between the axes of the blades = 19 mm
The weight of the complete set = 5.5 g
