This is the APC 4.75x4.75 Speed 400 Electric Propeller. The APC propellers undergo a specialized pultrusion process, enabling a higher density of fibers (60%) in comparison to the resin (nylon binder). This unique construction provides exceptional strength and stiffness, surpassing the capabilities of glass-filled nylon. The added stiffness effectively controls vibration resonance response, while the increased strength enables the utilization of thinner cross-sections, resulting in advantages for weight reduction and aerodynamic efficiency.
Key Features:
• Computer-optimized design grants these propellers a slimmer profile, delivering increased efficiency and a more substantial grip on the air,
all while minimizing noise production.
• Constructed from lightweight molded nylon, these propellers significantly reduce rotating mass, resulting in heightened output and
an extended operational lifespan.
• Reinforcing fibers are incorporated into the construction to ensure a consistently precise pitch at any RPM.
