Some may find this a bit of interesting L.M. Cox model rocket history. It is an early Cox Model Rocketry Poster tri-fold brochure. It includes a swing-wing glider illustration and description called the Astra Glider, which was never released but would have been unique if it had, because all of the original Cox model rockets were constructed of injection molded ABS plastic and were ready-to-fly or almost ready-to-fly. This poster/brochure was pre-1972, because Cox issued it's initial Model Rocket Catalog in 1972: http://www.ninfinger.org/rockets/ca...2/72coxcat.html , which was more developed/formalized than this earlier poster/brochure which only featured artist renderings of the Cox model rockets.

Sorry, I wasn't able to do a continuous scan to keep the tri-fold poster all together. Perhaps someone with some graphic skills can stitch the three pages back together. This tri-fold poster was the interior of a Cox Model Rocketry Poster/brochure. I'll also submit the exterior pages in another post on here following this one.

I'm hoping that someone who knows, like Bob Sanford (Initiator001) or someone else, can fill us in on more of the L.M. Cox Model Rocket history.

I recall that the igniters, and pad, were different. Pre-production concept drawings!

Liked their 18mm D8-3 and D8-0 motors.
Don't think a 13n-sec motor is possible in a 70mm case now with the weaker BP Estes now uses.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !

They apparently didn’t keep the “Astra” moniker going forward either. I think the Cox stuff first entered the market about 70-71.

Rocket-Brained Since 1970

All of the Cox D8 motors I have are dated sometime in 1971.

There are some clues to help date the introduction of the L.M. Cox model rocket engines and kits as well as the Cox Model Rocketry Poster/brochure. Notice in the Cox Astra Engine illustration on the brochure, there is a 1969 date on the engine label.

Also, later, in the released Cox Launch Control Instruction Manual, the last page provides some additional clues on the dated release of some of the Cox model rockets. Both the Uprated Saturn 1B and the Saturn V models show availability as of June 1970. Plus, the igniter illustration on the last page of the Cox Launch Control Instruction Manual shows a different style of igniter than the Astra igniter. The style shown in the Cox Launch Control Instruction Manual is the style that Cox ultimately released instead of the Astra igniter with sockets for the two prong connector shown in the Astra Launcher illustration. In addition, notice that Cox added legs to the Launch Control Pad that was actually released vs. the Astra Launch Control Pad did not show any legs on it.

These clues lead me to believe that the Cox Model Rocketry Poster/brochure was likely printed in late 1969 or early 1970.

Crude but effective... I "stitched" the brochure together and it ended being a 20 megabyte PDF, even at a smaller size. Originally it was over 30 inches tall but I decreased the size to 25 inches tall... still too big to post. I took a "screen shot" for all to enjoy.

Faithwalker: If you divide the scans into five sections instead of three then I could do a better job at "stitching" the pictures together. Just FWI I am using PowerPoint, the "poor man's" graphic program, to stitch these. Then I "print" the file using doPDF 10 to "print" the file, that is how I do my decals and it works fine.

The swing wing boost glider is interesting. The design appears to be lifted directly from the swing wing boost glider illustration pictured in the group of boost glider types that Stine published in the Handbook of Model Rocketry.

Too bad this awesome looking BG model never made it to market.

Thanks, Raúl, for stitching the Cox Model Rocketry Poster sections together and for explaining how you did it! Perhaps I'll attempt to try it with PowerPoint myself to see if I can improve the image. Will get back with you.
