@cargasm..... thanks for the advice... I think we have already proven that well balanced blades can result in no Jello at 1080 both in the Hero2 and 3. We are trying to eliminated Jello from 2.7k shooting, significantly higher resolution and therefore more susceptible to the Jello effect. And sorbothane maybe a pretty cheap solution.
And I use the gopro housing because I push it to far and crash a lot
I'd rather have shorter flight times and keep my camera safe.
