Introducing the Multistar carbon fiber propeller series. Because the carbon construction is so much stronger, we can make the props ultra thin allowing these props to offer increased performance with reduced current draw and increased efficiency. Perfect for your multirotor project, these 8x4.5 inch props are incredibly stiff and very well made using top quality carbon fiber. They feature a tight weave giving maximum strength and are pre-balanced so you can just bolt them on and away you go.
Diameter: 8 inch
Pitch: 4.5 inch
Hub Thickness: 7.0mm
Shaft Diameter: 5~6mm (with adapters)
Weight: 5.1g each propeller
Note: These props are for electric use only.
Unit Weight (g):
They need a fair amount of balancing but they are pretty decent otherwise. Would purchase again.finishing not very good, balance is quite off. the worst thing is it's less efficient than my nylon props. for the same current, this prop gives about 10-20pcnt less thrust, not very ideal at allThese props look nice and well done, unfortunately there is no more good to say.
"... and are pre-balanced ..." this is totally wrong.
"... offer increased performance with reduced current draw and increased efficiency ..." this is also wrong, compared to my cheap cracked SF plastic prop the efficiency is very low, where I used to need 1/3 throttle to lift my quad, I need around 2/3
This is really disappointing, I have have 4 pairs for sale :)good quality . So nice
these props are great value!
They need balancing and quite some of it too, but for the price you can't beat these.
Also they track very good, the adapters look like alu so thats also great.
I'll probably come back for these or the 9x5 version if this is not big enough.
