These machined folding prop spinners feature a lightweight aluminum spinner cone with a machined aluminum yoke assembly. The yoke is held onto a smooth motor shaft with a compression-type collet. They are available in 5 different diameters with multiple shaft size options to fit a wide range of aircraft motors. These spinners are a very standard design and can be used with our GemFan folding blades as well as most other brands of blades that use a 8mm hub with a 3mm bore hole.
A pair of M3x12mm Phillips flat head screws are used to hold the prop blades to the yoke assembly, and a M2 Phillips flat head screw is used to hold the spinner cone in place onto the compression collet assembly.
