Fixed-Wing 18x8 Wooden Propeller MA1880B by Master Airscrew  [MA1880B]

18x8 wooden blade for model aircraft performance

The Master Airscrew MA1880B is a wooden propeller with an 18 inch diameter and 8 inch pitch, built for fixed-wing RC aircraft where a wood blade is desired for response and handling. The 18x8 sizing provides a specific thrust and speed tradeoff suitable for many sport and scale electric setups when matched to an appropriate motor and ESC. This entry covers compatibility checks, installation tips, and the relationship between pitch, diameter, and performance so modelers can set up and tune the blade correctly.

Fitting the prop is normally direct: confirm the hub bore fits your motor shaft or use the recommended adapter, secure it with correct hardware and torque, and perform a static balance before the first flight. After installation, verify motor and ESC current draw under controlled conditions to ensure the system remains within safe limits. Wooden props can be adjusted with careful sanding for balance, but avoid major reshaping without testing each incremental change.

From a tuning perspective, an 18x8 wooden prop generally gives stronger midrange thrust at moderate RPM rather than absolute top speed compared with smaller, higher-pitch props. Adhere to the motor manufacturer's static thrust and current recommendations and ensure your ESC and battery can cope with the load produced by this blade on your chosen motor and mounting arrangement.

For sport or scale electric aircraft that call for an 18x8 wooden prop, the MA1880B provides a conventional wood option with clear guidance on fitment and balance to help ensure safe, predictable performance.
