This GM CL Competition Line 30 mm spinner is extremely light and compact, and when used with matching GM CL prop blades facilitate an incredibly streamlined and low drag folding propeller installation. They also come with special rubber bands that ensure that the blades fold strongly against the fuselage sides. The carbon cones have openings cut in to keep these bands nicely in place.

The special yoke (also called hub or centre piece) used in the GM CL Spinner incorporates a design idea that originated with F5B hubs. An additional 10 degrees angle is added to the yoke and subtracted in the prop. This has no effect when the prop is open but results in the blades being twisted 10 degrees and lying flatter to the fuselage when folded. Also by using specially designed less twisted propeller blades any gaps between the folded prop and the fuselage are further reduced, minimising drag when gliding.

The blades are attached to the yokes with polished steel pins which have loose fit inside the yoke and slightly tighter fit inside the blade. To disassemble the set just use a rod or a hex screwdriver with diameter bellow 3mm and push the pins out. When reassembling the set GM advise applying small amount of oil to the bores of the yoke to prevent the pins from sticking. The spinner cone has milled slots to keep the blade folding rubber bands in place. The yokes are completely hidden inside the spinner cone and cannot be interchanged as clearance between yoke and cone is very tight.
