This will be a fun build - The Astron Skydart II. It first appeared in the 1972 Estes catalog as K-57.
Larry Renger was the designer. He also developed the classic Falcon Boost Glider.
Pop Pod boost gliders were pretty new then. The first Citation Bomarc and was a pop pod glider.
With a "pop-pod" glider the internal engine tube ejects and descends by parachute. The eject pod allows the elevator to raise and the model glides in.
The online instructions are a different format for Estes and worth a look. To see them, CLICK HERE. There are differences between the original and re-issued kit.
The original kit hard cardstock formed nacelles on the underside of the wing. The new kit uses a split BT-50 tube.
The original kit included a pre-bent elevator retainer wire. The current kit uses three glued together pieces of balsa.
