Gemfan Multirotor Carbon Fiber T-Style Propeller 10x5.5 Black (CW/CCW) (2pcs)
Hobby Square Singapore
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.
