I'm flying a Kaos right now. I got nothing but praise for it. If you put that .46 on it I think it will have all the speed you want. It has done all the aerobatics that I know how to do and it flies like it is on rails. The only complaint I have is that the covering had some wrinkles when I got it. I few minutes with a iron took care of that though. And it is a good deal, I paid just over a hundred bucks for it and put it together in two evenings.
