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 multi-rotors, you can either use the standard 4mm center hole or you can use a tightening cover with 9mm centers and M2 bolts.

Not a big price difference, but a bit cheaper Multirotor Carbon Fiber T-Style Propeller 5x3 Black (CW/CCW) (2pcs) PRODUCT ID: 505000062-0 seems and feels exactly the same to me. I bought both sets for my 205 sized quads with DYS BE1806 motors to see the difference, but you might as well go for the cheaper set.first of all: dont buy these props for a mini race quad!
- they have extremely low thrust compared to the gemfan 5040 and even the 5030!
- on the first outdoor flight the carbon propeller just broke like a plastic one!
so they look good but I definitely wouldn't buy them again!Absolute disaster props compared to standard Gemfans of the same dimension, I ran multiple tests on my Turnigy thrust stand and always got considerably less thrust on these at virtually identical power draw as the Gemfans... Motors were MS Elite 2204 2300kv. Prop data available on RCGroups http://www.rcgroups.com/forums/showthread.php?t=2377984#post31162250
