Yes, it was the phenomenon of the decade, when George Lucas first dropped us head-first into the world of Luke Skywalker, Princess Lia and Darth Vader. The opening scene of that film, with the Republic Corvette being pursued by the Imperial Star Destroyer cruising "above us," was a masterstroke of cinema special effects and evidence of movie model-building "par excel lance."
Needless to say, when these models became available, anyone who was "sci-fi motivated" snapped them up.
Most of the Star Wars models I built are now many years old, done either after the initial release of the kits, or shortly thereafter. One model which was built from scratch but is now commercially available, was the Y-Wing Fighter. The ship played a big role in the first film's final scene, so I felt compelled to build one myself. It turned out to be a "flying model," capable of rocket powered flight and parachute recovery.
The scratch-built Y-Wing Fighter. Just like the movie models, this one was built from parts procured from other model kits. For rocket flight, fin units had to be slipped over the thrust-vectoring extensions of the engines to place the center of pressure behind the center of gravity. Because of its weight, the model flew with an Estes "D" engine.
The Republic Snow Speeder, as seen in "The Empire Strikes back," second film of the original series. The MPC model was well detailed. Painting was done from information from magazine articles and movie still frames.
The "Incom T-65 X-Wing Fighter," as flown by Luke Skywalker in the Death Star battle. Original MPC model. Surface scarring and battle damaged was added to give the model a weathered look.
Han Solo's "Millennium Falcon." The original MPC model kit, done with weathering and panel discoloration on all exterior surface to replicate the look of the movie model.
Darth Vader's special TIE (twin ion-engine) Fighter. The MPC model includes a Vader figure seated in the cockpit.
The Estes TIE Fighter flying model rocket. Aside from its ability to be launched, it's a fairly well detailed model of the standard TIE Fighter. For flight, the front "windscreen" comes out and the rocket body inserts into the model from from to back. The side panels of the TIE provide the "fins" for guidance.
Our old friends, C3PO and R2D2. Both were original models sold by MPC.
