Xoar PJA (2 Blade) / PJI (3 Blade) Beechwood Prop is the most popular propeller for Model Airplanes.

Xoar Propellers are ONLY made of Grade A Beechwood for excellent physical property in minimizing elongation, breakpoint and distortion rate by heating process.

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 PJA Wooden Propeller. With numerous tests understanding the physical limitation 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, a 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 prop is manually balanced. A set number of props were selected randomly in each batch and put on 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 PJA also offers a Pusher Series - PJA-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.
