Universal metal flexshaft coupling to suit 5mm electric motor shaft, uses a grub screw fixing to motor shaft and a collet style adapter to suit 5mm flex-shaft.
Overall length 34mm
Bought this for my traxxas spartan after upgrade to flex shaft and it works great had no problems and at a very small priceIdea and price are good but manufacturing tolerances do not match and gaps between parts are too big. Especially the thread is too loose which makes the nut bent on its side when tightened. the adapter was not able to be lined properly and caused terrible vibrations into the shaft. So wasn't able to use it. maby someone else has more luck with these.That one has a Motorshaft of 5,01mm and flex-shaft of 4,81mm. And has NOTHING TO DO WITH 6mm - to 5mm!
That is absolutely WRONG AND UNUSEABLE!
That is a absolutely lie:
Boat Flex-shaft Coupling To Suit 6mm Motor Shaft - 5mm Flex-shaftIMPRESSIVE TO SAY THE LEAST IT IS MORE LIKE 5MM TO 5MM THAN 6MM TO 5MM BUT MY MOTOR IS 5 MM.
