Vintage Cox Model Rocketry Poster tri-fold brochure
 
3 Attachment(s)
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.

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

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

Have you flown any of your D8s? Curious about performance, not sure I’ve ever heard about performance, or even reliability.

I flew a Cox D8-0 at NARAM-52.

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.

Don't you wish we could still get motors at these prices shown in the attached Cox Engine Order Form? Notice the Cox engine specs and the igniter details for the released versions vs. the Astra version shown in the Cox Model Rocketry Poster/brochure.

Used to fly the Cox D8-3 a lot in my Mars Landers and 1284 full-stack Space Shuttles.
Just about the perfect motor for them. I'm down to only 3 D8-3s and one D8-0.
All the Cox motors I have are of a 1971 production date. The majority were flown in the mid 80's to early 90's. The last one I flew was in 2005 in a Mars Lander.
Used the Cox D8-0 to CHAD stage various rockets such as the Estes Patriot and Nike Ajax.
Never had one cato either.
Wish we could get those back. Just enough over an Estes C, but not to the level of a D12 or an Aerotech D. I don't think with the modern weaker black powder they would be possible in a 70mm casing. Estes should offer a "long" 18mm motor like they offer a "long" 24mm motor with the E12.

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.

The November 1969 issue of Model Rocketry Magazine: http://www.ninfinger.org/rockets/Mo...02n02_11-69.pdf , page 29 (frame 31), has an introduction of the first L.M. Cox ready-to-launch Model Rocket kits: 1/125 scale Little Joe II, 1/24 scale Honest John and 1/24 scale Nike Zeus.

The April 1970 issue of Model Rocketry Magazine: http://www.ninfinger.org/rockets/Mo...02n07_04-70.pdf , page 11 (frame 13), shows the Cox Dyna-Soar prototype model and the Saturn V that were to be introduced in late Spring 1970, but, to my knowledge, the Dyna-Soar did not ever get released. I don't believe that the Cox Saturn V launch tower was ever released either.

A few weeks ago I was able to pick up an envelope of literature concerning this Cox poster/brochure.

The envelope was post marked May, 1970 and included the poster/brochure (I've attached a full, stitched version below), along with scanned copy of the cover letter and the price list which was on the back of the cover letter.

Interesting to note the Saturn V tower (which, as has been previously stated, was never released) was set to cost $9. Would have made a nice addition had they ever released it.

Hi Earl,

Nice find! Thanks for sharing with us to help confirm the date of the Vintage Cox Model Rocketry Poster! It is interesting that the poster portrays the Astra Glider, but the included order form/price sheet instead lists the Dyna-Soar glider (which is not on the poster illustration) and the included order form/price sheet does not mention the portrayed Astra Glider, although the order form/price sheet does mention all the other model rockets depicted.

Would be nice if some company would offer a scale Saturn V/1B tower one could actually use that is NOT made of cardboard.
A thermoset flame-proof plastic would be good.
As it would have a very limited audience, it most likely would be cost prohibitive to produce.
Just seeing the prices of plastic scale airplane kits are now ridiculous, a scale tower would be over $200.

I'm looking for the 18 mm size motor retainers for the Cox Honest John, are there any available and what would be the cost? t?

This is what he's looking g for. See attached. There may be a 3d printed one 🤔

If not anybody that has a Cox Honest John could take some close up photos from the rear with a ruler and perhaps one could be 3d printed.

Skaffman 03-30-2022 11:41 AM

Cox Motor retainers
 
Yes, that's the one .If there aren't any available would someone be able to 3d print some for me? I posted this in the 3d print group on Facebook on Facebook but I haven't gotten a response yet. I've sent out numerous requests to a number of different sources but I have yet to get a reply except to say that they would probably have to be 3d printed.I did find one person who said they had some but he didn't have the 18mm size.

TigerHawk 03-30-2022 12:27 PM

Alex at Boyce Aerospace Hobbies might be able to help you?

Someone on the other forum informed me that he has the 18mm retainers for the Honest John and he's sending me one.So once I get that I can have someone make some for me.That was a surprise, I didn't think there were any more left to be found out there.So now when I do get theHoJo it's gonna see plenty of flight time. And another thing, is there a possibility of finding the original parachutes?I don't really think so but I thought I'd ask anyway.

shockwaveriderz 03-31-2022 04:49 PM

If you get them 3d printed please consider posting here.

Here are what I show for Cox engine clips, I dont have the Cox Little Joe II so can not speak with authority on it, but believe it uses the same 18mm clip as the others, also note on the Nike, the booster loads from the top, and the "ejection tunnel" is the retainer for the booster section, turned by the "key" included. Also the Saturn 1B has the option of single 24mm or dual 18mm.

Cox also had a #5057 Snap-in 18mm engine retainer clip, which was white in color. See attached views below and see attached parts list.

The Cox #4960 Twist-lock 18mm engine retainer clip was gray in color.

Both of these type engine retainer clips would work on the Cox Little Joe II, the Cox Honest John and the Cox Nike Zeus.
