Emax Avan 2.5 Inch Babyhawk TinyHawk 3-Blade Propeller Set (2x CW / 2x CCW) EMAX Avan Rush 2.5 Inch Props 3 Blades Propellers CW CCW for Emax 1106 Motor Lipo 3S to 4S Emax Tinyhawk II Freestyle Emax 1103 7000kv 1s to 2s or Similar Motor (surpass hobby 1104 7000kv) 1.The Emax Avan Rush propeller 2.5x1.9x3 was designed for Emax Tinyhawk II Freestyle 2.5 inch conversion kit to maximize performance and flight time. 2.This propeller is matched to Emax 1106 4500kv for 4s or the Emax 1106 6000kv on 3s. Can also be used with 1103 7000kv for 1s or 2s Lipo or 1104 7000kv 1s or 2s lipo. 3.A true 1.9" pitch throughout the blade gives a linear control feeling across the throttle band while still achieving high speeds. This allows for ease of flight and more precision. 4.With a special PC blend the Avan Mini weighs 1.25 grams. Utilizing thicker airfoils greatly increases durability and stiffness. 5.The Avan Rush was designed from the ground up starting from design constraints such as RPM, air speed, and required thrust. From these constraints aerodynamic models were built to predict performance and to design the blade shape. 6.Highly cambered airfoils were used to achieve high lift coefficients at high angles of attack prolonging stall. 7.A special Polycarbonate blend is used to achieve high durability. The Emax Avan Rush propeller 2.5x1.9x3 was designed for Babyhawk Race 2.5-inch conversion kit to maximize performance and flight time. This propeller is matched to Emax 1106 4500kv for 4s, the Emax 1106 6000kv for 3s, and Emax 1103 7000kv for 1 or 2s power in the Tinyhawk Freestyle.

With a special PC blend, the Avan Mini weighs 1.25 grams. The Avan Rush was designed from the ground up starting from design constraints such as RPM, air speed, and required thrust. From these constraints, aerodynamic models were built to predict performance and to design the blade shape. Highly cambered airfoils were used to achieve high lift coefficients at high angles of attack prolonging stall. This allows for a higher blade angle while still remaining efficient. The cambered airfoils also allow a greater flight envelope making for great low-throttle responsiveness while still being able to achieve high speeds. A very versatile Prop for many flying styles.
