are my propellers too loose? (Video and Pictures)

[andycorleone]

I upgrading my JDI F550 with RCtimer HP2212 motors I think they are very similar to Sunnysky x2212, I bought some carbon fiber prop from Hobby King

with came with 2 adapter each

when I install the prop to the motors with the smaller adapter I think they are too loose, please watch the video:

They don't look horribly loose. Do they feel loose when the adapter is clamped down on it? That disc that goes on top should tighten them down secure once the nut is on there.

there should be a diameter listed with both the motor (shaft) and the prop adapter. Make sure they are not the wrong adapters for the shaft size. Also, grab some Nyloc nuts if those aren't already. They will hold much better than a typical nut.
