Falcon 24x20 Carbon Fiber Contra-Rotating Rear F3A Propeller
The Falcon 24x20 Carbon Fiber Contra-Rotating Rear Propeller is a competition-oriented propeller designed for the rear position of an F3A contra-rotating electric power system. Its lightweight, rigid carbon fiber construction provides the precision and consistency required for demanding pattern-aircraft applications.
Each Falcon propeller is handmade from premium graphite material, individually inspected, and factory pre-balanced. Careful attention is given from the hub to the blade tip to support smooth, efficient, and dependable performance.
Important: This is the rear propeller only, part number C2CR2420R. It is intended for the rear position of a compatible contra-rotating F3A propulsion system. The matching front propeller is sold separately.

Compatibility
This propeller is designed for the rear position of a compatible contra-rotating F3A propulsion system using an 8 mm propeller mounting arrangement. Confirm the required propeller diameter, pitch, rotation position, bore size, motor specifications, controller specifications, and aircraft clearances before installation.
Do not use this rear propeller as a substitute for the corresponding front propeller. Contra-rotating systems require the correct front and rear propellers to be installed in their designated positions.
Installation and Safety
- Confirm that this is the correct rear propeller for your contra-rotating system.
- Inspect the propeller carefully before every installation and flight.
- Perform a final balance check before use, even though the propeller is factory pre-balanced.
- Verify that the propeller hub seats securely and evenly against the mounting surface.
- Use the mounting hardware and tightening procedure recommended by the drive-system manufacturer.
- Confirm adequate clearance between both propellers, the spinner, the fuselage, and surrounding components.
- Never operate a propeller that is cracked, chipped, damaged, improperly mounted, or out of balance.
- Keep people and loose objects clear of the propeller arc whenever the aircraft is powered.
Balance Notice: Falcon propellers are individually inspected and pre-balanced. However, the manufacturer recommends performing a final balance check before use because shipping and handling conditions cannot be controlled.
