About the Orbital Transport

The Estes Orbital Transport was introduced in Catalog #683 in late 1968. It was designed by Wayne Kellner, one of the most prolific and innovative designers at Estes Industries. The Orbital Transport was based on an early NASA scramjet design for the Space Shuttle. It featured a parasite glider that deployed at ejection and parachute recovery for the booster. The Orbital Transport was released as Cat. No. K-42 and had an introductory price of $2.50.

The Semroc Reproduction Orbital Transport is very close to the original with some modern changes. The original balsa nose cones are kept. All fins are precision laser-cut balsa with slots located to allow parts to come together perfectly straight and in the proper location. A Kevlar shock cord mount is added for better retention. The original rubber shock cord is replaced with elastic. The 18” parachute is reduced to 15” for less drift. The Glider hooks are updated to include a double hook. The Body Tubes are beefed up for better finishing and durability. Assembly is easier as Construction Tools or Jigs are also included in the kit.

If this is not enough to get you excited consider switching up the colors. Semroc has a variety of different color decals to make your Transport look like your own fleet.

Thank you Phil Queen and Randy Boadway for collaborating on the improvements to make this updated kit happen. And a special thanks to Phil Queen for some of the best engineering done to date.

    This kit was so much fun to build again, and it looks so good I probably will just keep it on display. Thanks for bringing it back!
