I've seen a Madness fly and it is really capable. I saw it do pretty much everything without a problem, WITH wing tips strangely enough, (I know, beats me!!!) The Madness is in my book, the godfather of these type of planes, everything else is a near copy. Oohhhh, and it can roll, quite nicely too, and all this is with a pilot who is nowhere near a hot shot!!!! I think that the guy who designed world championship models might just know a bit more about designing.
