Very well made prop with 4mm shaft size and 1.4 pitch.Very nice prop. Balanced, thinned and without a tongue, it's almost the same as a back-cut version except very light.
I have verified using a digital calliper that this is 40mm with a prop drive shaft hole of 4mm on the dot. As most propeller on sale are 4.76mm but has a copper adaptor to 4mm, you don't need to get it out of the old one. This bolts on directly.
I tried using a digital scale to see how heavy this thing is but it would not register so if you are looking for something very light, this is the propeller I would recommend
