The Emax Avan Flow propeller 5x4.3x3 was designed to maximize control while remaining efficient. A true constant 4.3" pitch throughout the blade gives a linear control feeling across the throttle band while still achieving high speeds. With a special PC blend the Avan Flow weighs 4.3 grams. Most of the weight is centralized near the hub creating a low moment of inertia of 13.4 grams*square centimeter which in turn makes a very responsive prop. Best match for 2206-2207-2306 motors around 2400kv.
The Avan Flow 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.
EMAX AVAN Flow 5x4.3x3 Tri-Blade FPV Propeller
The EMAX AVAN Flow is a 5 inch tri-blade propeller engineered for maximum control and linear throttle feel. Its constant 4.3 inch pitch throughout the blade delivers predictable, consistent response from low throttle to full send — making it the prop of choice for freestyle pilots who prioritize feel and precision over raw top speed. At just 4.3 grams with a low moment of inertia of 13.4 g·cm², it spools up fast and responds instantly to stick inputs. Best matched to 2206/2207/2306 motors around 2400KV.
