For reference: the Estes motor shipping tube I have is blue and parallel wound with an
ID (min)~ .92" and an OD (max) ~ 1.04". I'm giving the dimensions as min. and max. due to parallel winding of tube. Were Estes stated dimensions of BT-30 minimum and maximum diameters or average diameters? Min./Max. seems more logical. |

no, the shipping tubes have to accomodate the instruction sheet as well, which was thin paper, but nearly the size of regular notebook sheet, plus the strip of "astron" igniters. The 18mm motors rattled around easily. Also, IIRC, the packing slip would be rolled up inside if the order was for individual motors, say, a 1/2A.8-4, a B.8-4, and a B3-0 in the same tube.

Granted, I never saw an Estes motor shipping tube. All of my motor orders from the company were for very small numbers of individual motors, and they were rolled up in newspaper and packed in the box with my kit orders. None of mine were ever in tubes.

I built more rockets out of the motor tubes than I ever built from kits. Usually of the one flight variety.

Bought a lot of motors? No, not really. As a kid on a very limited budget, I could buy a kit or a tube of motors. A tube of motors came with it's own essential building block for a rocket. Very conveniently sized. I don't believe I ever let one go to waste. I didn't operate like that all the time and of course, these things weren't works of art, but they did (mostly) fly and I learned a good bit (good and bad). Again, as a kid, when I went out to launch, I didn't come back until I ran out of motors or rockets. Sometimes both.

How many motors did a tube contain? The most motors that I ever included in a single order were three (or possibly four), and no two were alike. But I never received them in a tube. In fact, I didn't know that Estes had ever packaged motors in tubes until after I brought my model rocketry hobby out of suspended animation in 2004.

The tubes held three motors. Sometimes an order that had more motors would come as multiple tubes, all separately addressed and with separate postage....bound together with rubber bands.
I don't recall if they put more than three shorties (Series III) motors in a tube or not.
