This is the APC 4.75x5.5 Speed 400 Propeller. By employing an advanced pultrusion process, APC propellers exhibit exceptional manufacturing quality. This technique enables a higher density of fibers (60%) to resin (nylon binder), resulting in superior strength and rigidity compared to propellers made with glass-filled nylon. The enhanced stiffness effectively mitigates vibration resonance response, while the increased strength permits the utilization of thinner cross-sections, promoting reduced weight and improved aerodynamic efficiency.
Notable Features:
• Computer-optimized design optimizes propeller profile, generating increased efficiency and reduced noise
• Constructed with lightweight molded nylon for minimized rotating mass, resulting in enhanced output and extended lifespan
• Incorporates reinforcing fibers to maintain consistent pitch at any RPM
