Prop propeller balancer shaft size Typhoon Q500 4K

[photousa]

Hey All, new Typhoon Q500 4K owner here. Does anyone know the correct size for the prop balancer shaft or rod. I believe it's 8mm 1mm but I've seen two sizes listed for the Q500 and I want to make sure I purchase the correct prop balancer, Thanks

According to this seller, the size is 6 mm.

However, this is the rod I use. It seems to be more sensitive because of the narrower shaft size. I just place it on top of a tall water glass. That works much better than a prop balancing jig.
