About the Gemfan Street League Hurricane 7043 Propeller
This gemfan streetleaguehurricane 7043propeller setof 4 is the Hurricane 7043 in the Street League specification, finished in midnight black. The 7043 designation gives the geometry: a 7 inch diameter disc with a 4.3 inch pitch, in a three-blade configuration. The blades are moulded in polycarbonate, a tough thermoplastic chosen for propellers because it deforms and recovers rather than shattering on contact, and each propeller weighs about 10 g. The hub is drilled for M5 motor shafts. The set contains four propellers made up as two clockwise and two counter-clockwise units, which is the arrangement a quadrotor needs so that rotor torque cancels across the airframe. Ordering as a matched set of four keeps blade geometry and mass consistent around the aircraft.

Typical applications
A 7 inch three-blade propeller at 4.3 inch pitch is the long-range and cinelifter class of multirotor propulsion: more disc area than the 5 inch propellers used on short-range airframes, with the third blade adding thrust and smoothing vibration at the cost of some efficiency. Polycarbonate construction is specified where airframes are flown in proximity to obstacles and propeller strikes are expected. As a four-piece CW and CCW set, the item replenishes a complete quadrotor rather than a single arm.
