9055 Carbon Fiber Propellers CW and CCW Rotation with Dual Mountings (1pair)
Extremely lightweight and durable, you can expect an increase in overall motor efficiency owing to the ultra thin and stiff carbon construction. The dual mountings mean these will fit on most multi-rotors. You can use the standard mounting with the 4mm shaft (ream for larger shafts) or use a tightening cover with 12mm centers and M3 bolts.

Very good propeller, needs a little bit of tape to balance them but they work well.Best propelers for my quad. Noiseless and eficient. Strong to take some punch from the ground. Well ballanced .the only think that i not like is that two 3mm holes for bolts are smaller and need to be drilled.Someone wrote that they have the propellers must be balanced! obviously they must, but a small piece of tape on the blade so are they perfectly-balancedI have just done my first flight with these (on a SK450 dead cat conversion).
I had to balance them and increase the hole size to 5mm, but I am quite happy with the result: tracking is ok and less vibrations than with the 10x4.5 g e m f a n plastic props.
