adattatore lega con vite senza testa e cono in lega di fine.1pc soltanto.
Super gute Qualitt......I was surprised they are finished well and work great.
They are for larger prop's with at least 8mm inner diameter also the washer is 22mm wide.
I use them on 4 Turnigy D3530/14 1100kv with carbon fiber prop on a 450 quad copter.good quality, low price..It seems very strong and good finishing, but when I put it on Aerodrive 3548 790KV with APC 13x4 that was balanced, in flight it start to vibrate alot over half throtle. It is not balanced!!!Fits great, good for nose weight as it aint light!The adapter is useless due to the eccentricity of the cone central hole. The consequent shaft vibration is surpassing by far any acceptable level.used it on a NTM 3548 1100 kv 11x7 prop ...well wobble wobble... on the third flight came off in mid air and flew away.Did try to sail down a 1200 mm balsa Mustang but in the end when speed droppt it tipp stalled and crashed.Did not manage to instal it wobble free.If you use a NTM motor, change motor mount and use the treaded prop axel.Sorry this item can not be trusted.Good double grub adapter, (Why show two when selling one ? beats me)Wieder ein Artikel den man bei der nchst grsseren Bestellung mit in den Warenkorb legen kann.SXIT, I received and very wrong. I thought motor shaft is 5mm also prop is 5mm. But prop shaft is 8mm how can I put 1147, or 1247 all these propeller? bec all props come with 6mm hole. nobody answer and DEMM IT... I bought this motor 3635, 5mm shaft and don't know how to put propeller. last time I bought collect type spinner also the same prop shaft is 8mm, I try to drill and use it, but on the air the propeller is crack by 2 pics . SXIT...
