Falcon 23x20 Rear Contra Carbon Fiber Propeller (F3A Electric)

Falcon 23x20 Rear Contra Carbon Fiber Propeller

The Falcon 23x20 Rear Contra Propeller is designed for the rear position of an electric contra-rotating propulsion system. Its lightweight carbon-fiber construction and specialized rear-blade design make it well suited for F3A pattern aircraft and other precision aerobatic models using a compatible contra drive.

Important: This listing is for the rear propeller only. It must be paired with a compatible front propeller and contra-rotating drive system. It is not intended for use as a conventional single propeller.

Specifications

Propeller Pairing

This 23x20 rear propeller may be paired with a compatible Falcon front contra propeller. One commonly recommended combination uses a 23x18 front propeller with this 23x20 rear propeller. Pairing requirements can vary according to the aircraft, motor, contra drive, and desired flight performance.

Drive Compatibility

Falcon contra propellers are commonly used with compatible F3A contra systems, including selected Gaishen, Brenner, Adverrun, and CRS drives. Confirm the required front and rear propeller sizes, hub dimensions, rotation, and mounting specifications for your particular drive before ordering.

Always perform a final balance and condition check before installation. Verify that both propellers are fully and securely clamped by the drive’s mounting system before operating the motor. Never operate a propeller that is damaged, cracked, loose, or improperly mounted.
