Has anyone ever TRIED three bladed props on their P3?

No, is there such a thing available

Actually there are .... but they are rubbish.
You won't find that they do anything faster, further or better than the props that DJI design engineers designed to match the ESCs and motors.

Thanks Guys. kind of what I figured and I thought maybe they'd over stress the motors anyway.
