S7 Competition Models
The list of competitive prototypes for the S7 Scale event has been fairly limited.
The Saturn 1B is a popular prototype - in fact more World Championships have been won with 1B's than with any other prototype. The Apollo 7 Saturn 1B drawn by George Gassaway is a great example of the "workshop drawing" that must be included in each scale documentation packet.
Other popular prototypes include Arianes 3 and 4, and the Soyuz.
The Space Shuttle (or Energia/Buran) would appear to be a great candidate for the event, but it has yet to be proven in competition. It is a very difficult model to fly in a manner consistent with the prototype.
