Sail Propeller USA uses the best-quality material from German to make all of its propellers. The German Pollmeier lumbers are pre-treated, which is important for minimizing elongation, breakpoint and distortion rate. CNC digital imaging process ensures consistent quality in diameter, propeller blade profile and pitch. The propeller shape is optimized to be the most efficient by computer simulation and real-flying experience. Each of Sail Propeller is well-balanced twice before and after it was painted. All of these make Sail Propeller USA stand out from other RC Propeller competitors. What's Included: 1 x Sail Propeller USA Y-A20x8 RC Model Airplane Propeller (CCW Puller/Tractor prop). *Please Note: Final balance check is suggested before flight due to external factors such as temperature, handling during transit may vary the balance of the propeller.
