There was also the Centuri kit and outfit. I know your title says Estes, but this was from 82-83, after the two companies started interchanging things including parts, catalog publishing, etc. The Centuri shuttle kits were still done with Centuri parts and styling, including the classic Powr-Pad in the outfit. The kit was very similar to Estes 1385 in design but didn't have "real" OMS pods.
