Looking over the original Star Blazer instructions, I remembered a few questionable things from the 1970s kit.
A BT-20M is 2.25" long. The nose block takes 1/4" of the usable space. The nose cone shoulder takes away another 1/2". That leaves a whopping 1 1/2" of BT-20 for a payload.
TIP: If you ever wondered what the Estes tube designations mean: CLICK HERE
After gluing on the fairing strips they have to be cut where the body tubes butt together! There's no reason for this. It'd be much easier for the builder if Estes included a single BT-20 tube that was 8 3/4" long.
Maybe some of those "FREE KITS" were made up from surplus parts?
The front angle cuts form the windows when you sand the top round.
TRIVIA: When looking through some old catalogs I noticed that the Star Blazer was the first kit to use a raised canopy feature. Others followed like the Interceptor the following year.
