APC Thin Electric Propeller, 7 x 4E

Thin Electric Propeller, 7 x 4E. This propeller is compatible with airplanes and is manufactured using a pultrusion process that allows for a higher fiber to resin density. This provides greater strength and stiffness than glass-filled nylon, which is beneficial for controlling vibration resonance response. The higher strength also allows for thinner cross-sections, which is beneficial for weight and aerodynamic efficiency.
