Folding propellers are for airframes that have to pack: tube-launched, collapse-for-deployment and long-range cruisers. The line covers 6-inch and 10-inch, in two- and three-blade, in glass-fiber-reinforced nylon.
Folding propellers are multi-part assemblies — individually molded blades on a hub with pivot hardware — so blades are the replaceable consumable, and blade sets are weight-matched.
Material follows application, not size: glass-fiber-reinforced PA66 where a platform needs stiffness under load, polycarbonate where it needs impact survival and low rotational mass. Several sizes are offered in both.
