Size & Pitch of Propeller

So desert aircraft is dealer of Xoar props, they sent me link to their props. If you look at the 22x8 propeller specs they tested using 150kv motor and 80amp esc. So pretty close to our setup. I’m really interested in trying this type of prop if can mount. Do you guys think a rubber washer will hold the prop in place on the stand-off?

Interestingly they also have same prop in wood with more pitch options, it looks like they also have a swoop tip design to them.
