CN 7×4 Folding Prop Blades (2mm Hinge Pin)

A pair of CN Models 7×4 prop blades suitable for the F5K and other small electric gliders. These blades have a flatter high aspect ratio shape and should fold closer to the fuselage, reducing glide drag.

These blades require smaller spinner/hub assemblies with 2mm diameter hinge pins. Note this product consists of two carbon propeller blades only. The central spinner/yoke assembly is not included.
