This is a well constructed propeller adapter at a fraction of the cost sold elsewhere. I purchased this 6mm propeller adapter in the event that in the future I purchase this ... HobbyKing Donkey ST4010-820kv Brushless Motor PRODUCT ID: ST4010-820 ... or a similar motor with a 6mm shaft from the USA warehouse(s), since the USA warehouses do not stock the 6mm size. For that matter they don't stock all sizes as does the International warehouse. So while ordering from the International warehouse I decided to pick up the 6mm size just in case of future need. Shipped from the International warehouse on 17/09/2014 ( dd/mm/yyyy ) registered ( tracking ) air mail with Singapore Post and it arrived through the USPS San Francisco ISC to me on 26/09/2014 . That was FAST !!! Thanks a lot Hobby King ( also known as ( aka ) Hextronik ). [ By the way, USPS San Francisco ISC denotes United States Postal Service San Francisco International Service Center. ]Precisely machined and finished. -1 star because the stopping surface for the prop didn't have friction ribs.good look and very well done. Perfect for my scopeNicely maid addapter cheep price.
