Design & Performance
Manufactured using a pultrusion process, this propeller boasts a higher fiber-to-resin ratio, enhancing strength and stiffness compared to traditional glass-filled nylon props. The computer-optimized design ensures a thinner profile, resulting in reduced noise and improved aerodynamic efficiency. Its lightweight construction minimizes rotating mass, leading to better throttle response and extended motor life.
Included Accessories
-
One set of adapter rings (LPAR18SF) to fit various motor shaft size.
For optimal performance and reduced vibration, it's recommended to balance the propeller before use. This propeller is intended for electric motors only and is not suitable for glow engines.
