adattatore lega con vite senza testa e dado di metallo.1pc soltanto.
Shaft was bended when arrived so I couldn't overcome the vibration problem. And also a bit heavy for such a little thing.Light weight but made of a strong aluminum alloy material. Only the 3mm nut is made of a steel materiel. Has two grub screws so it secures to the motor shaft well. The diameter of the propeller shaft is 3mm and the length of the propeller shaft is 12.5mm from its tip to the base of where the propeller butts up against the adapterexcellent product very good materialExelent for micro motorsNice and secure mount just remember the threadlock on those grub screws or you be looking in the grass for your prop ;-)Excelente produto, qualidade e acabamento excelente..
Excellent product, excellent quality and finish.These are EXCELLENT...as long as you get the ones that are actually centered. Ordered 3...only 2 are useable. One is so off center, it shook violently enough to crack the foam on my Suk when I bench tested it.
If you need a couple of these, order twice as many. They're cheap enough.used on a ammo brushless motor,and it gained more thrust than prop directly on shaft. excellentUsing this on my Cessna Micro (Nataku). It's much better then the plastic prop adapter included.
The prop shaft may be a bit loose for a 3mm diameter GWS prop but it's easily fixable by putting a 3 or 4mm heat shrink in the propeller shaft.
I had much less vibration with this compared to the original plastic adapter. I am using a GWS4025 prop.Also works well on small edf motors e.g. for pusher props on small flying wings.
