Ralph, I just got done reading through 11 pages and over a year long thread on props for the H, so forgive me if I missed something.
I just recently got my H and have only flown it a small handful of times but went looking for some backup props which is how I stumbled on this thread.
I see your replacement hubs and am considering it. I did see someone comment a ways back (not sure on what page) about making sure they are VERY snug so they don't come off on motor stop.
I had the Q500 4K for a short time, and they have a rubber O-ring at the base of the hub that gives the prop something to tighten against. I see from your pictures about there is a little room between the top of the hub and bottom of the blade base. Would it work to have a rubber O-ring there for the prop to snug up against?
