Yuneec Propeller Set A for Q500 Typhoon / Typhoon G Quadcopter (CW, 2-Pack) YUNQ4K115A Compatibility: for Q500 Typhoon / Typhoon G Quadcopter Feature: The Yuneec Propeller Set A for Q500 Typhoon / Typhoon G Quadcopter contains two clockwise (CW) rotating props for installation left front and right rear. Note: While these propellers will work with all Q500 Typhoon models as well as the Typhoon G, the propellers must be paired with the CCW version of the same model: i.e., YUNQ4K115B. This is because the profile of each propeller differs slightly.
