Size of balsa block in the Star Blazer (K-31)
Does anyone know the size of the balsa block that was included with the original Estes Star Blazer (K-31)? It its listed as NCS-3, but I cannot find a reference for the size of the original piece.

Look at Figure 3 in the original K-31 plan. It says "...Start with block 1" x 1/2" x 3.1"..." Now, look near the bottom-left of the same picture. It reads "...Block in kit is ample for two complete canopies..." The block would most-likely be 1" x 1" x 3.25", which would allow for trimming. You split the block down the middle...

Thank you, John. I actually like that design (the original K-31) over the simplified rework of the Star Blazer in 1972 (TK-31/0831).

Are Series III Engines (the shorties) available anywhere?

They are not being made today. You could try to buy some from a collector. If your intent is to fly them, use 13mm motors and an adapter. Bill

I still have my original K-31 Star Blazer (one of the few of my original rockets I still have). I cloned it (and did a far better job). On the clone I just fitted it with a 13mm motor mount.
I agree wholeheartedly that this one is much prettier than the later models bearing the same name.

Furthermore, the 18mm ½A6-2, A8-0, A8-3, A8-5 and B6-0 are all suitable to be cut down to series III lengths. If you do this, use a razor saw and stuff a little wadding in the forward end to guard against any sparks setting things off. It's a pretty remote chance, but it can happen. Anyway, between the six T-motors and these five 18mm motors, you can create a very nice family of ersatz series III motors By the way, a Midget rips on a B6-0S to A8-5S combo. Doug .

I still have my original Star Blazer. When I ran out of shortie motors I glued a 13mm motor mount into it.
Now I wish I had left it original and used 13mm motors in a adapter.

Cloned upsize
I'm still planning to upsize both Star Blazers using my favorite BT-55 and N/C combo.
