Hey thanks for the offers of help.
I have the hanger 9 katana 50. It will probably be in the 7 to 7.5 lb range and wing area of 825. I am not radical 3d pilot. I want to do imac style maneuvers and maybe some beginner 3d stuff like harriers and flat spins. Just leary of putting to much weight on the plane and having a flying rock. I am kindof leaning towards the 10cc but dont want of have this model fly like the previous katana that I had with a .70 surpass. It needed all the engine could give and mush it way up till it got some speed then it would fly ok.
thanks
Jeff
