Since the materials are not here yet, and building process will take a while (and I mean, a *while*), I've built an X-Plane model of Sky Pup so I can have at least an idea of how it flies. I'm sure it's a rather crude model, although, I used the official plans for modeling it, so, hopefully, it's somewhat close.
X-Plane is great when it comes to experimenting with designs. Now I know, for example, why there's 6° dihedral in the design, or what happens to the plane if you install a 1000-lbf jet engine on it :)
The absence of ailerons is nothing too taxing, though. Well, as long as you don't decide to do barrel rolls or some other stupid shit: this plane is not designed for any type of aerobatics :)
