Gemfan Hurricane 51366 – MCK ReV3 Three-Blade Propeller for FPV Racing Drones
Gemfan Hurricane 51366 MCK ReV3 PC 3 Blade is a three-blade propeller developed in collaboration with FPV pilot MCK, designed for fast throttle response, strong acceleration and precise control on racing courses. Its polycarbonate construction, 129.7 mm diameter and 2.8-inch pitch suit FPV drones that require control on both straights and through consecutive turns.
Gemfan Hurricane 51366 is optimised for 6S power systems with high-KV motors. It is suitable for racing and track practice, where pilots need to adjust speed quickly and link individual manoeuvres into a smooth flight path.
129.7 mm Diameter and 2.8-Inch Pitch
The propeller has a diameter of 129.7 mm, approximately 5.1 inches, and a manufacturer-specified pitch of 2.8 inches. Gemfan Hurricane 51366 therefore belongs to the 5-inch class of FPV propellers, although frame compatibility must be assessed using its actual diameter.
Propeller pitch describes theoretical forward travel during one complete rotation. Actual thrust and flight behaviour also depend on blade shape, motor speed, drone weight and overall power system configuration. When choosing a propeller, consider the manufacturer’s published dimensions and your drone’s technical requirements alongside the model number.
MCK ReV3 Blade Design for Racing
ReV3 development focuses on quick response and control through turns. Its three-blade construction and racing-oriented blade profile support rapid acceleration after braking or changing direction.
During track practice, predictable throttle response helps pilots control thrust when approaching gates and exiting turns. Propeller suitability can be assessed by how accurately a desired flight path can be maintained and how much correction is needed through consecutive manoeuvres. Flight controller settings and piloting technique also influence the result.
Polycarbonate Construction and 4.2 g Weight
Gemfan Hurricane 51366 is made from polycarbonate, also known as PC, and each propeller weighs 4.2 g. Polycarbonate combines low weight with impact resistance, making it practical for frequent training and racing.
The propeller has a hub thickness of 6.6 mm and a maximum blade width of 14.9 mm. These dimensions help determine mounting compatibility and required clearance.
Check the condition of blades and hub after a collision. A deformed or cracked propeller can cause vibration and affect control precision, so any damaged propeller must be replaced before the next flight.
5 mm Mounting Hole and Motor Compatibility
The propeller’s centre hole diameter is 5 mm. The manufacturer recommends 2306- or 2207-size motors, taking into account each motor’s shaft, mounting arrangement and permissible load.
Motor size alone does not determine overall system compatibility. Motor KV rating, battery voltage, electronic speed controller current rating and frame clearance must also be checked. Hub thickness must suit the motor’s mounting arrangement so that the propeller can be secured correctly.
During installation, select a propeller with the correct rotation direction for each motor and check that the blades can rotate freely.
A Suitable Choice for a 6S Racing Drone Setup
Gemfan Hurricane 51366 MCK ReV3 is aimed at pilots looking for a responsive racing propeller for a 6S FPV drone. Matching its characteristics to the motor, drone weight and flying style is particularly important.
When trying a new propeller model, compare throttle feel, cornering behaviour and motor temperatures after flight. This helps determine whether the selected combination delivers the desired speed and control precision during both practice and racing.
