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.
As supplied these propellers are ready to fit a 5mm shaft but this can be reamered to suit shafts up to 7mm, adapters for a 4mm shaft are also included.

Need balancing but after balancing are fine. Hubs are a bit better made than the more expensive Carbon Fiber Propeller 5x3 Black (CW/CCW) (2pcs) set (PRODUCT ID: 445000128-0).These props actually performed quite well. Bought 4 pairs, 6 of 8 were balanced well. The two that were out of balance, were out of balance at the hub, which is hard to correct.This is the worst propeller I have ever used on my QAV 250, really disappointing. The quad were shaking badly. Flew right after with the 5x4 carbon nylon propellers and all worked.
