APC Props
AP-04541E
This is the APC 4.5x4.1 Speed 400 Electric Propeller. APC propellers undergo a pultrusion manufacturing process that results in a higher density of fibers (60%) compared to the resin (nylon binder). This unique construction provides exceptional strength and stiffness, surpassing that of glass-filled nylon. The increased stiffness effectively controls vibration resonance response, while the enhanced strength allows for the utilization of thinner cross-sections, benefiting weight reduction and aerodynamic efficiency.
Key Features:
• Optimized by computer design, these propellers feature a slimmer profile and deliver enhanced performance with reduced noise levels.
• Crafted from lightweight molded nylon, these propellers minimize rotating mass, resulting in improved output and extended lifespan.
• Reinforcing fibers are incorporated to ensure consistent pitch at any RPM.
