Thanks to the nylon material used in construction these propellers offer increased performance and efficiency making them perfect for your multi-rotor project. These 10x4.5 inch props are incredibly stiff compared to other plastic propellers available and are precision molded to ensure optimum balance from the factory. They feature multiple prop adapters to enable these props to fit any prop shaft from 3mm to 6.5mm diameter.
Diameter: 10 inch
Pitch: 4.5 inch

Shaft Diameter: 3~6.5mm (with adapters)
Weight: 12g each propeller
Note: These props are for electric use only.

Not sure if I got a bad batch. I have checked them against my 11" and 9" props I have for the same quad and it appears the outer 3 inches of the blade has the leading edge lower that the trailing edge. Either badly manufactured or a poor design, either way in practice they are virtually useless. At full throttle there's not enough thrust to even lift off the ground. I checked it several times to make sure I didn't mess up the positioning. Just a dud prop, and I bought 2 sets.Very bad balanced propps and the design is poor , create very turbulence , in a quadcopter you can think that are a fail in the motors but really the problem are this propsI put these props on my quadcopter drone, replacing GWS 10x4.5 that had worn out, and the drone wouldn't take off. I then tested the thrust of these props on a test bed and they generated less than half the thrust as the old propellers at the same RPM! Looking at the profile of the prop edge-on, the leading edge appears to be curved down. These are terrible props.
Very very soft Props. Mounted on my 1,2kg quad with 980kv motors, they bend sharply when I accelerating. Its not possible to fly a straight line oder fast spins, very poor balanced, but the centerholes are ok. Material is ok, it doesnt brake at first ground contact.Those are actually very cheap and look nice. But they're simply unusable. VERY poor balanced, not even taken out of the form they were made in; there are still lots of plastic rests at the end of the Propellers which you have to cut off. Also, if you spin them on the Motor, you can see that the blades hit the same place at different levels, so even that is totally out of balance.
Was worth a try, but I would never buy this crap again. But they're very cheap so it's not a big matter.Ottime eliche, ma ricordate di non stringere troppo forte il dado del motore, pena la distruzione in volo delle eliche. comunque necessario bilanciarle.
