I love to build too. But I don't have that precious commodity....time. As an example, I have been working on a Spacewalker II. Just finished painting the wing, and have the fuse masked right now. Started building it six years ago. Yuck.
So these higher quality ARFs have really been a boon to me. I bought the Cermark Pitts after seeing it. Fun Plane!!!
Otherwise I would forget how to fly beween projects
