Falcon 31x12 Carbon Fiber Propeller for Gas RC Airplanes

Falcon 31x12 Carbon Fiber Gas Propeller

The Falcon 31x12 Carbon Fiber Gas Propeller is designed for large gas-powered RC airplanes that need a balanced combination of thrust, smooth throttle response, and efficient forward flight performance. The 31x12 configuration is a strong all-around setup for larger aerobatic, scale, warbird, and sport aircraft.

Built from carbon fiber, this propeller provides the rigidity and durability needed for demanding large-scale RC aircraft applications.

Best For

• Large aerobatic aircraft
• Scale and warbird airframes
• Large sport aircraft
• Pilots wanting balanced thrust and forward speed

Typical Engine Class Range

This propeller is commonly used on larger gas-powered RC aircraft requiring balanced thrust, acceleration, and efficient forward flight.

• Large 85cc–100cc class gas engines, depending on aircraft type, exhaust setup, RPM range, field elevation, and flying style.

Always verify propeller recommendations from your engine manufacturer before installation. Engine load, RPM target, muffler or pipe setup, aircraft weight, and flying style can all affect proper propeller selection.

Precision Construction

This propeller features a factory-drilled 10mm center hole, approximately 0.3937" or 25/64". Falcon carbon gas 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 built for demanding gas-powered RC aircraft.
• Balanced Performance Profile: The 12-inch pitch provides a practical blend of thrust, acceleration, and forward flight efficiency.
• Large Diameter Airflow: The 31-inch diameter moves strong airflow for larger airframes and high-power gas setups.
• Responsive Throttle Feel: Lightweight carbon fiber construction can help provide crisp throttle response when properly matched to the engine.
• Efficient Blade Profile: Blade design supports smooth airflow and stable performance during demanding flight conditions.
• Factory Pre-Balanced: Pre-balanced to help reduce vibration, with final balance verification recommended before installation.
• 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 31x12 propeller is generally considered a balanced option compared with lower- or higher-pitch propellers of the same diameter. It can provide a useful blend of low-speed pull, acceleration, and efficient forward flight when matched correctly to the aircraft and engine.

If your setup needs easier spool-up, stronger acceleration, or more low-speed pull, a lower-pitch propeller may be a better fit. If your goal is increased forward speed and your engine can maintain RPM under load, a higher-pitch option such as a 31x13 or 31x14 may be appropriate.

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.
