10x4 Beechwood Electric

XOAR PJN 10x4 2-Blade RC Airplane Propeller Wood Prop for Electric RC Planes (10×4 Tractor) Overview: Xoar Propellers are ONLY made of Grade A Beechwood for excellent physical property in minimizing elongation, breakpoint, and distortion rate. The uniquely designed hub and blade profile create one of the lightest wooden propellers for electric flights. After years of experience and feedback from pilots and customers, and results from international competition, the initial design of XOAR's PJN Wooden Propeller was developed. With numerous tests understanding the physical limits of different kinds of wood from different manufacturers, Xoar carefully selected the one, and only one, that met the requirement of moisture content and physical properties of elongation, breakpoint and distortion. Xoar then validated the design in digital imaging and other necessary procedures to prove the design not only meets the specs, but also is safe to fly. After approving the design, pre-cut wood is transferred to the CNC manufacturing program. After CNC, the semi-finished prop comes into shape. Each prop is manually finished to reach perfect surface smoothness and balance which makes Xoar props stand out from the competition. During the coating process, two layers of primer coating and two layers of glossy protection coating are applied in order to prevent corrosion. Each XOAR prop is manually balanced. A set number of props is selected randomly in each batch and put on the inspection bench for dynamic balance testing, RPM test, and noise level check before they are packaged and shipped.
