Tamiya has an excellent 1/100 shuttle kit.
The 747-100 is the variant that carries the shuttle. It has a wingspan of 195 feet and a fuselage length of 230 feet. Hopefully that helps in determining the scale.
I'm planning to also build a shuttle + 747 combo in the near future, but at 1/200 scale.

I have never heard of it but I'm a ww2 junkie so I'm not surprised. I'm interested to see whats up with it though.

I thank it is the same kit I had back in the 80s that was released by Entex. If so it is a great model kit and is 1/100 scale. Tamiya makes a Shuttle that scale but I am not sure it is readily available.
