APC props are manufactured using a pultrusion process. This method causes the fiberglass "fibers" to be oriented axially in 1/2" long pellets, allowing for a higher fiber (60%) to resin (nylon binder) density. Providing substantially higher strength and stiffness than glass filled nylon. The additional stiffness is beneficial to control of vibration resonance response. The higher strength allows the use of thinner cross-sections, beneficial to weight and aerodynamic efficiency. Competition proven. Dark gray composite material.
