Harmonics led to metal fatigue failure of hub plate.

Hmm and just how can someone measure that after the prop has cracked? Chicken or the egg not possible now unless your motor has measured vibration now with new prop. I seen lots helio blades do strange things but most not all have another underlying cause.

Simple things as plates are too hard, to soft, wrong alloy, seen metal mismarked etc, so not to sure I buy that your motor did it unless you have vibration now, can be scanned very easy by helio mech with spectrum anyalizer have to do it on helio's most every 100hrs. Glad you caught it before they slung off gets ugly fast then :thumbleft:

I hear ya, Bigun. There certainly could be other answers. The Excalibur always made an odd noise that was never there with the 6 blade Saber I ran for a few months earlier this year or the 6 blade Warp I'm running now. You've probably already seen my description but the best way I could describe it was like the sound made when blowing across a bottle or, better yet, swinging a pipe through the air. I never really felt it, just heard it. In retrospect, I wish I had played with pitch on the blades, perhaps even stagger as had been suggested by others. It's a great prop and did everything I wanted. Maybe I need a scan. Now where to find a helio mechanic? You know one? :wink: :lol:

I tried knitting for a while. Kept sticking myself in the fingers. Had to give it up. :lol: You know the old saying:
