Xoar PJN (2 Blade) / PJI-E (3 Blade) is a wooden propeller for RC Electric Airplanes. Xoar Propellers are ONLY made of Grade A Beechwood for excellent physical property in minimizing elongation, breakpoint, and distortion rate. DESIGN PROCESS After years of experiences from our pilots' and customers' feedback and international competitions result, we came up with the initial design of XOAR's PJN Wooden Propeller. With numerous tests understanding the physical limits of different kind of lumber from different manufacturers, we carefully selected the one and only one that fit our requirement of moisture content and physical property in elongation, breakpoint and distortion. We 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. PRODUCTION PROCESS After approving the design, pre-cut lumber is transferred into 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 Prop stand out from our competition. During the coating process, 2 layers of primer coating and 2 layers of glossy protection coating are applied in order to prevent corrosion. Each of the XOAR props is manually balanced. A set number of props were selected randomly in each batch and put on the testing bench for dynamic balance test, RPM test, and noise level check before they are packaged and leave the factory to our customers' hands. Xoar PJN also offers a Pusher Series - PJN-P. WARNING Final balance check is suggested before flight due to external factors such as temperature, handling during transit may vary the balance of the propeller. ABOUT XOAR PJN / PJI-E BEECHWOOD ELECTRIC PROPELLER Xoar PJN / PJI-E Beech wood propellers are made to the highest standards by combining excellent craftsmanship and technology. Xoar PJN / PJI-E is specially designed and manufactured for electric flights. The unique aerodynamic blades are shaped to produce the highest efficiency and stability when compared to plastic propellers available in the market. Xoar PJN / PJI-E also offers an amazing flight endurance when compared to plastic props due to its stronger blades and lighter weight. The light-weighted propellers put less strain on the electric motors and yield accurate performance in maneuvers by spinning up and slowing down in a speedy manner.
