Aluminum Folding Prop Spinner, 50mm (2") Diameter for 6mm Motor Shafts

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. 

The 50mm spinners have a Spinner Cone that is 50mm (2 inches) in diameter with an overall length of 40.5mm (1.59 inches). The Center-to-Center distance between the prop attachment screws on the yoke is 55mm (2.17 inches), and the complete spinner assembly weighs 22.6 grams or 0.80 ounces. This spinner includes a 6.0mm collet to fit motors with a 6mm smooth shaft.
