Hi all, I'm wanting to try something else in the way of props on my 80 HP 912 in the Kitfox 4. I have a set of 72" square tip warp drive blades and a two blade hub I can put them in. Has anyone run this combination on a 80 HP 912? Probably not enough prop on the 100 HP, but maybe the 80 HP??? Any thoughts or comments? JImChuk
