Falcon 31x13 Carbon Fiber Propeller for Gas RC Airplanes

Falcon 31x13 Carbon Fiber Gas Propeller

The Falcon 31x13 Carbon Fiber Gas Propeller is designed for large gas-powered RC airplanes that prioritize efficient forward flight, smooth throttle response, and stable performance under load. The 31x13 configuration is commonly used for speed-oriented setups where maintaining airspeed and clean flight characteristics are important.

Built from high-quality carbon fiber, this propeller provides excellent rigidity, durability, and consistent performance for demanding large-scale RC aircraft applications including aerobatic, scale, warbird, and sport aircraft.

Best For

• Large aerobatic aircraft
• Scale and warbird airframes
• Large sport aircraft
• Pilots looking for increased forward speed compared with lower-pitch propellers

Typical Engine Class Range

This propeller is commonly used on large gas-powered RC aircraft that prioritize efficient forward flight and stable RPM under load.

• Large 85cc–120cc class gas engines, depending on aircraft type, exhaust setup, RPM range, and flying style

Higher-pitch propellers require proper engine tuning and sufficient power to maintain RPM efficiently during flight. Always verify propeller recommendations from your engine manufacturer before installation.

Precision Construction

This propeller features a factory-drilled 10mm center hole measuring approximately 0.3937", or 25/64". Falcon propellers are individually inspected and factory pre-balanced to help reduce vibration. Final balance verification is always recommended before use.

Key Features

• Carbon Fiber Construction: Lightweight, rigid, and designed for demanding gas-powered RC aircraft.
• High-Pitch Performance: The 13-inch pitch is commonly used for efficient forward flight and higher-speed setups when properly matched to the engine and aircraft.
• Large Diameter Airflow: The 31-inch diameter provides strong airflow for large-scale aircraft and high-power gas setups.
• Responsive Throttle Feel: Lightweight carbon fiber construction can help improve throttle response and overall responsiveness.
• Efficient Blade Profile: Blade design supports stable airflow and consistent performance during demanding flight conditions.
• Factory Pre-Balanced: Designed to help reduce vibration and improve smooth operation.
• Propeller Covers Included: Helps protect the blades during storage, transport, and field handling.
• Precision Manufacturing: Consistent blade shape and carbon fiber construction help support reliable performance.

Technical Specifications

Propeller Selection Note

A 31x13 propeller is generally considered a speed-oriented setup compared with lower-pitch propellers of the same diameter. It can provide increased forward speed and efficient cruising flight when the engine has enough power to maintain RPM under load.

Compared with a lower-pitch option such as a 31x12, the 31x13 may place additional load on the engine while providing stronger forward flight characteristics. If your setup needs easier spool-up, stronger acceleration, or more low-speed pull, a lower-pitch propeller may be a better fit.

Important Safety Reminder

Always inspect the propeller before use. Check for cracks, chips, delamination, shipping damage, hub fit, bolt pattern, spinner clearance, engine RPM range, and ground clearance before flying.
