I had a P4 hub and prop wear out after about 15 mos. / 36 flying hours. The hub was worn and started slipping in the prop when you started the motors. Sounded like a large zip-tie tightening. Glad it didn't happen in flight. I changed the bad hub and all the props at that point.
I just had my first hub fail after 1 year and about 140 miles of flight. The edges that make contact with the inside of the prop wore down. The whole assembly started to slip on motor start. Made a braaaappp sound and the prop wouldn't turn for a split second... $9 for a replacement Prop Install...

I'm 2 hours from New Haven, CT.
I've left my stock cap on several times with no apparent damage. When I got the Polar Pro cap, I attached a small "Remove Before Flight" streamer to it. Hasn't happened since!
