The Quanum series of carbon fiber propellers have been specially designed for multi-rotors and are manufactured to very exacting standards. They are extremely light and strong and you can expect an increase in performance due to their ultra thin and stiff carbon construction.
These propellers have dual mountings which means they will fit most large multi-rotors, you can either use the standard 8mm center hole (which can be reamered for larger shafts) or you can use the 4 hole fixing with 20mm centers for M3 screws which most larger brushless motors have.
These props are supplied with a very nice soft carry bag to keep your props in when they are not mounted to your mult-rotor.
