This is the APC 11x4.6 Slow Flyer "SF3D" Propeller, a remarkable choice for slow-flying applications. Crafted using an advanced pultrusion process, APC propellers feature an exceptional fiber-to-resin density ratio, with an impressive 60% fiber content in the nylon binder. This innovative composition provides substantially higher strength and stiffness when compared to glass-filled nylon alternatives. The additional stiffness plays a pivotal role in controlling vibration resonance response, while the increased strength enables the use of thinner cross-sections, resulting in improved weight reduction and enhanced aerodynamic efficiency.
Key Features:
• A computer-optimized design ensures these propellers possess a thinner profile, delivering increased performance with reduced noise levels.
• Constructed from lightweight molded nylon, these propellers effectively reduce rotating mass, leading to higher output and an
extended operational lifespan.
• The inclusion of reinforcing fibers guarantees consistent and precise pitch maintenance at any RPM, ensuring optimal
performance throughout your flights.
