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.
This set of props are self-tightening and have an insert fitted to suit 5mm motor shafts with colour coded hubs for easy identification.
Pitch: 4.5 inch
Weight: 5g each
Rotation: Clockwise and counterclockwise

Nice props, but the nuts are reversed. You have to put the cw props on ccw prop shafts, which means you have to switch adapters on the motors if that is an option. Probably need threadlocker to keep props on, haven't tried yet. Going to order more props before commit to changing prop adapters around.BE AWARE!!! The Black bolt propeller does NOT screw to the motor shaft!!! The Silver one is ok though. I don't know why, tried hard several times...
