Features:1. A true constant 4.3" pitch throughout the blade gives a linear control feeling across the throttle band while still achieving high speeds.2. The Avan Flow was designed from the ground up starting from design constraints such as RPM, air speed, and required thrust.3. From these constraints aerodynamic models were built to predict performance and to design the blade shape.4. 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.5. The cambered airfoils also allow a greater flight envelope making for great low end responsiveness while still being able to achieve high speeds.Description:The propeller 5x4.3x3 was designed to maximize control while remaining efficient.Specifications:Brand: EmaxMaterial: PlasticDiameter: 5 inchPitch: 4.3 inchBlade: 3 BladesPackage Included:12 pcs * PropellerNotes:1.
