I got AVI catalogs right up to the end. They actually owed me a little money.

AVI never promised composites; they did actively sell some unusual BP motors. Some of my first F flights were on their chunky 35mm motors. I flew them in a minimum diameter (T-35 tube) with a plastic Nike Smoke nose cone. Man, did that thing move!

Here is the sell sheet:

AVI did offer lots of vaporware. I won one of their design contests in 1977 or so. I bought a hell of a lot of old MPC and MRI and AVI stuff, but some of the fascinating stuff I really wanted never actually shipped:

One item was a line of nesting tubes which could be used to form cones, boat tails, transitions, and so on. A special filler would be used to smooth out the "jaggies."

Another cute item was a mail rocket, the ANTARQUI as I recall, which would have adhesive stamps and envelopes and stuff.

They also promised some interesting "alien" space fantasy rockets.
