My $.02
A few years ago a wellington Fl. resident was killed when the Velocity he was flying (WITH his family BTW) had his IVO come apart. Violent crash.
First the facts as observed by myself...
Then, a few months after this crash, I was looking for a prop for my kitfox (bought a warp drive, but my LYC pulses, even with a harmonic balancer, tore it up.....now my new Catto is actually in transit, finally!!!! Thanks Craig !), and I went to Palm Beach Propeller at Lantana Airport in Fl., to get some used prop ideas...PBP had an actual Ivo blade, sent from Ivo himself, that was delaminating. Ivo apparently was looking for a dependable NDT process to check for delamination. This blade he sent to PBP was one that had delaminated in the middle of it's span. Now, the next day I called and spoke to Mr. Ivo himself, and guess what he said..."Nope, no crashes I know of...None have come apart...... A N D , he 100% totally denied the fact that PBP had one of his "delaminating" prop blades, since he does not have this problem ,with his props". Kind of funny, since PBP even showed me later the invoice from Ivo with his name on it.
So, now comes my IMHO.......Go ahead and put an Ivo prop on your plane, but PLEASE don't fly over my house or start your engine near me. Yet another great idea that fails lethally in application.
