Falcon 21x10 Carbon Fiber Propeller for Gas RC Airplanes

Falcon 21x10 Carbon Fiber Gas Propeller

The Falcon 21x10 Carbon Fiber Gas Propeller is designed for gas-powered RC airplanes that need a balanced combination of thrust, smooth throttle response, and efficient forward flight performance. The 21x10 configuration is a practical all-around choice for many sport and aerobatic gas aircraft.

Built from carbon fiber, this propeller provides the rigidity and durability needed for demanding RC aircraft applications while helping maintain consistent blade shape under load.

Best For

• Sport and aerobatic gas RC airplanes
• General-purpose gas power setups
• Pilots wanting balanced thrust and forward speed
• Aircraft where a 21-inch gas propeller is recommended

Typical Engine Class Range

This propeller is commonly used on gas-powered RC aircraft that require a useful blend of acceleration, pull, and forward flight efficiency.

• Large 35cc–40cc 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 10-inch pitch provides a useful blend of thrust, acceleration, and forward flight efficiency.
• 21-Inch Gas Propeller Size: Suitable for properly matched sport and aerobatic aircraft that call for a 21-inch gas propeller.
• 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 21x10 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 acceleration, pull, and efficient forward flight when matched correctly to the engine and aircraft.

If your setup needs easier spool-up, stronger acceleration, or more low-speed pull, a lower-pitch option such as a 21x8 may be a better match. If your goal is increased forward speed and your engine can maintain RPM under load, a higher-pitch option such as a 21x12 or 21x12.5 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.
