The Modular Shuttle system was the first LDD model that I designed. A lot of the design elements eventually went into the Oberon Class Scout. This one was inspired a lot by the Eagles from Space 1999. The middle section has a removable passenger pod, and I had originally envisioned designing other types of pods, like cargo containers, but eventually mode onto the Oberon class. The design features a rear propulsion section that opens up to reveal a detailed reactor system. The parts for this ship would have cost around $400 when the parts were still available, so needless to say, it never got built in real life.
