Gemfan 40MM-2 Blade Tiniwhoop Props(2ccw+2cw)

Inject blistering speed and agile cornering recovery into your indoor micro racer with the premium Gemfan 40MM-2 Blade Tiniwhoop Props. Engineered specifically to maximize efficiency within tight protective ducts, this ultra-lightweight propeller profile minimizes rotational mass to give your micro quadcopter instantaneous throttle response. Whether you are racing through tight basement gates or diving down indoor stairwells, the Gemfan 40MM-2 Blade Tiniwhoop Props slice cleanly through the air, providing a locked-in, drift-free flight experience that makes technical maneuvering feel effortless.

Durability meets high-rpm optimization. Because micro whoop drones regularly encounter walls, furniture, and race gates, the Gemfan 40MM-2 Blade Tiniwhoop Props are molded from premium high-impact polycarbonate. This flexible yet rigid plastic allows the blades to bend during hard impacts rather than snapping, letting you turtle-mode back into the air instantly. Additionally, the balanced 2-blade design reduces high-frequency battery current draw compared to heavier tri-blade props, lowering electrical noise feedback to keep your flight controller's gyro running clean and completely free of video "jello" artifacts.

🛠️ Key Technical Features

• Propeller Diameter: 40mm sizing optimized for standard 65mm and 75mm micro whoop frames and ducts.
• Blade Geometry: Agile 2-blade layout designed for maximum top-end speed, low rotational inertia, and swift throttle response.
• Pitch Profile: 1.0-inch or 1.5-inch pitch tuning depending on stock, providing smooth freestyle control loop management.
• Hub Configuration: Standard 1.0mm or 1.5mm center hole press-fit mounting options matching common micro brushless motors.
• Material Composition: Forged from high-elasticity polycarbonate plastic to survive repeated indoor impacts and gate crashes.
• Package Quantities: Ships as a full matching set of 4 propellers (2 Clockwise - CW, 2 Counter-Clockwise - CCW).

A 2-blade propeller features less total surface area, which drastically reduces aerodynamic drag and lowers the rotational inertia of the motor. On the track, this translates to higher top-end speeds, faster straight-line acceleration, and significantly longer flight times because the motor pulls fewer amps from your 1S battery pack. In contrast, 3-blade models provide slightly more grip and cornering punch at low RPMs but sacrifice battery longevity and peak speed due to the extra weight and drag. 

These 40mm micro propellers are engineered to push onto high-kv brushless motors typically ranging from 0702, 0802, up to 1102 stator sizes. When checking out your order variations, ensure you match the propeller's inner hub diameter with your motor shaft size—standard micro whoop motors utilize either a 1.0mm or 1.5mm shaft line. Choosing the correct press-fit mounting ensures the prop grips the shaft tightly without slipping or flying off during high-throttle maneuvers.
