Thanks for the info, glad the plane is doing well. I have been flying my Katana for 3D mainly, but found out when I bring the cg forward its a very, very, good IMAC style plane. I am in the process of recovering it and putting a set of MTW cans in it to quiet it down a little bit. Its quite noisy when using the 27x10 P-tip on it for 3D, but not that bad with the mejzlik on stock mufflers. I wasnt really wanting the AM 3 blade, but thought about trying one of their 2 blades.
