The Astron Star Blazer
It certainly wasn't a favorite design but at thirteen years old a free rocket was always a good thing.
This rocket used "Short" engines. They were 18mm engines but one inch shorter at 1.75" long.
On this face card illustration the recommended engines were the 1/4A3-1S, 1/2A6-2S an the 1/2A6-4S.
I don't remember ever using a 1/4A3-1S engine. In a rocket this size that would be like a MicroMaxx flight with the one second delay.
The Star Blazer made its first catalog appearance in 1970.
The engines are more powerful now, with a 1/2A6-2S, A5-2S and A5-4S.
The Star Blazer had an interesting design feature, the hand carved canopy.
Here's the illustration from the Estes instructions.

The Star Blazer disappeared in the 1972 catalog. At this time, many of the "S" engine models were being replaced or redesigned for the 13mm "T" engines.
A new Star Blazer appeared in 1973. This one I did buy.
Sleek and more modern, this time with an easier to make card stock canopy. The three fins were now squared off and not glued at a 120 degree spacing.

The catalog number was now TK-31. The "T" engine selection included the 1/4A3-2T, 1/2A3-2T, A3-4Tand A10-3T.
I was going to make a Star Blazer style canopy here on the blog. But those posts became much more involved than I thought. I might submit the posts as an article to the Apogee Peak Of Flight Newsletter.
