    Ralph, what kind of prop were you running? My IVO seems pretty flimsy. I do have a two blade warp 72" square tip, I might give a try at some point as well. Those blades are a lot stiffer then the IVO ones. Thanks for the reply as well. JImChuk

    My 912ULS has more of a harmonic around that 3,500rpm range as well. Smooth above and below. Airmaster 75" but it did it with the IVO as well.
