Simprop Zaunkönig

The Simprop "Zaunkönig" ("wren", small bird) is a small biplane design from way back (30 years?). At the time it must have been the smallest commercially available RC kit. It was powered by a small cox engine, and with the RC gear of the time the weight resulted in a model that's fast and challenging to fly.
