    Default Little insight as to what may have happened?

    We were filming with a Motly Crew and go pro, and the boat lost power randomly upon inspection both blades were clean broken off

    I wouldn't run that Octura prop raw (straight out of the package). They need to be balanced at a minimum to help prevent an imbalance and wearing out your strut bearing, and sharpening will improve performance. If you're not looking to spend a lot of money on props, but want an upgrade over plastic, you can get CNC aluminum props or Graupner Carbon (plastic composite) props inexpensively from OSE in that size. Neither needs to be balanced or sharpened.

    nice i will check it out. I have balanced multi rotor props etc... i assume it is similar, but you just remove material instead of adding?
