All Bravo III's spin the forward (bigger) prop counterclockwise and the outer (smaller) prop clockwise. There are no propsets that I am aware of that are the exact opposite of that.

That seems to be the consensus....

Maybe BBlades could help?

I'm no physicist but somebody must have done this test for max performance with bravo3s.

The way they have the props rotate allows them to use the lower gear of the upper gear set for the forward gear, which has more stability than the upper gear and the bolt on top cap, plus there's less stress on the lower clutch shaft and bearing when using the bottom gear for forward
