Seagull makes a 40 size Spacewalker ARF. Sig also has a kit of the 1/4 scale Spacewalker, but not the ARF. Sig also puts out a 1/3 scale kit I believe. The Great Planes Spacewalker ARF is a 1/4 scale in size if you were not aware of its size. Pretty big compared to that of a .40 size like that of the Seagull Spacewalker.

The 4 stars are a very popular second Plane. I personally think the sport is flooded with them, but still a very nice second Plane.
