Fantom was never sold as a finished product. Instead it was sold as a set of drawings. The drawings are not exact and should be used as a guide. Hobbex bought the rights to the drawings and have sold it continuously since the 1940s apart from a short break in the 1990s. Over 100,000 copies of the drawing were sold, but only ten documented builds were finished. The drawings had no measurements, and if you would follow the blueprints, you would not be able to open the door.
