This propeller is matched with an Emax 1106 6000kv for 3 sec and 4 sec. True 1.9&pitch across the blade gives linear control feeling on the other side of the band throttle, while still achieving high speed. This allows you to, it is simple, flight and more precise. Using a special PC mixture of Avan blur weighs 1.1 grams. By using thicker profiles, it significantly increases strength and rigidity. The center diameter also increases to thicken the root chord to maximize durability. Most of the mass is centralized near the center creating a low moment of inertia of 0.77 grams * square centimeter which in turn makes it a highly sensitive prop. In Avan, the blur has been designed from the ground up, starting with the design of constraints such as rpm, air velocity, and thrust if necessary. With these constraints, aerodynamic models were built to predict performance and to design the shape of the blade. Very much in
