i think the rule of thumb is 1 inch less and 1 more prop degree... so 12X6 = 11X7? just an example.

anyone know where i can get some good 3 blade props and nose cones?

You should check the thrust angle of the engine. The manual for the plane will tell you if the engine needs up,down,right,and left thrust. and maybe the incidence of your wing. If everyting is how it should be, I would not think that changing prop sizes should cause your plane to pitch up so much.

I have never heard of a switch to a 3 blade causing a pitch change. Sounds like something else changed. [8D]
