I know that with mine, I had the kit that came with the Katana S with the G-Force wing, which I guess is the newer style. I got the plans for the Katana S in the older style. The only couple of things that are really different is that the new Katana S doesn't have a pull-pull system, and the wing has three different layers. Try to set it up first just by sticking the pieces into each other(no glue yet) and to do it almost like a puzzle. Hope this helps.
