Propeller Adapter (Collet Type) Yellow 3mm
Motor Shaft: 3mm
Prop Shaft: 5mm
Prop Shaft length: 17mm
Weight: 4.2 grams
Does not fit 3mm motor shaft, it may be a 1/8" adapter, but definately slips off a 3mm motor.
Useless for my motorsThis Propeller adapters is very cool and Light. Have is red, blue, yellow, black and silver colors.In my case the ring slips too far over the shaft of the Prop adapter. So the prop cant be tightened. I have bought the 3.00mm and the 3.17mm version. Both have the same issue. I have dowloaded pics in the files tab.
