1655 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.

nice Finnish and strong. no flaws that i can see.Centre holes were not 4mm, if they can't manage to drill out a 4mm hole right, forget about these been balanced. One pair was some what close to balance while another pair was way out. Blades were firmer than some other cheaper E B ones. All holes seems like they were punched out rather than drilled, (cheaply produced products where machining tools are pushed way passed their usefulness/effectiveness). If you don't mind spending time DIY, these are passable. But I recommend looking at others. Only using mind for testing.Tarot ones are similarly priced but much better quality which HK should stock.Ordered 5 of these pairs. Well balanced propellers. Absolutely sturdy and doesn't bend at all.
Keep well of in air. I am happy with them.very nice propellers
