Emax AVAN Rush 2.5x1.9x3 2.5 Inch 1.5mm Shaft Propellers (2CW + 2CCW)

The Emax Avan Rush 2.5x1.9x3 propeller is specially designed for the Babyhawk Race 2.5 - inch conversion kit. It's a perfect match for the Emax 1106 4500kv on 4s or the 1106 6000kv on 3s, enhancing both performance and flight time. With a true 1.9 - inch pitch across the blade, it offers linear control throughout the throttle range while reaching high speeds. This means easier flight and more precise maneuvers. Made with a special PC blend, the Avan Mini weighs just 1.25 grams. Thicker airfoils boost durability and stiffness. Most of its weight is centered near the hub, resulting in a low moment of inertia of 1.24 grams * square centimeter, making it highly responsive. The Avan Rush was meticulously designed considering RPM, air speed, and required thrust. Aerodynamic models were created to predict performance and shape the blade. Highly cambered airfoils are used to achieve high lift coefficients at high angles of attack, delaying stall. This allows for a higher blade angle without sacrificing efficiency and provides a wider flight envelope, offering great low - end responsiveness and high - speed capabilities. A special polycarbonate blend gives it high durability, being tough and ductile to resist fracture in high - impact crashes. The thick blade root further enhances this durability. The injection - molding process is optimized to reduce bubbles in the plastic, increasing strength and maintaining superb balance. Geometry: 2.5 - inch diameter, 1.9 - inch pitch, 3 blades. Inertial Properties: weight of 1.4 grams, Moment of Inertia of 1.24 g * cm^2.

Using the Emax Avan Rush 2.5 - inch propellers is easy. First, make sure they are the right fit for your Babyhawk Race 2.5 - inch conversion kit and the appropriate motor (Emax 1106 4500kv on 4s or 1106 6000kv on 3s). Install them carefully, matching the CW and CCW propellers correctly. When flying, you'll notice the smooth and precise control. For takeoff, gradually increase the throttle, and enjoy the linear response. During flight, make small adjustments to the throttle for better maneuverability. When landing, reduce the throttle slowly. As for maintenance, after each flight, check the propellers for any signs of damage, like cracks or chips. If there are minor scratches, they might still be usable, but significant damage means it's time to replace them. Keep them in a dry and cool place to prevent warping. Also, don't forget to clean them gently with a soft cloth to remove any dirt or debris. And always handle them with care to avoid accidental damage.
