Hello; I built one of those 3 years ago, I bought a new Saito 150 for it too. It went fine I couldn't live with the landing gear mount however, and decided to move it all just before the wing mount. I bought the expensive fibreglass cowl and belly pan. I finished it all up, covered it with ultra cote, but I couldnt get the long gear mounted in a way that looks scale, so it has been sitting waiting for inspiration to appear.

I haven't seen any of these planes fly, but I have heard that they are wonderful flyers, this sounds likely to me as I have a GB extra and an Ultimate and they are wonderful flyers, as are their tiger, cub, falcon, and Protege.

I don't know if this is any help to you, just my own experience.
