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 or the Emax 1106 6000kv on 3s. 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. With a special PC blend the Avan Mini weighs 1.25 grams. Utilizing thicker airfoils greatly increases durability and stiffness. Most of the weight is centralized near the hub creating a low moment of inertia of 1.24 grams*square centimeter which in turn makes a very responsive prop.
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 end responsiveness while still being able to achieve high speeds.
A special Polycarbonate blend is used to achieve high durability. This material is incredibly tough and ductile to resist fracture in high impact crashes. A thick blade root was designed to further increase this durability. Our injection mold process is optimized to reduce bubbles in the plastic to increase the strength of the propeller and to maintain superb balance.

Update process is cumbersome, better if done with the VTX out of the quad. Also the update port is much flimsier than the earlier 2 antenna versions, IMO.
I use this mont for all my builds with a DJI O3 system. It comes with all the hardware nessassery and I like how is provides a small gap between the frame and the air unit so you can run wires under it. With all that said, it is still very low profile to fit on builds that use short 20mm standoffs too.
This thing is really fun and I haven't had to touch the PIDs at all. Super maneuverable on high rates and really mellow on low rates. I'm teaching my six year old grandson how to fly and he's doing great with it then raise the rates and I doing freestyle in my livingroom. Top off the performance with Newbeedrones awesome customer service and you can't lose. Newbeedrone is now my go to site for whoop stuff.
