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.

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.

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.

Kind regards,

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.

Kind regards,
Jeff Jenkins

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.

Just recently learned that graphic artist Otto Kuhni is the one who produced the attractive eye-catching illustrations for the L.M. Cox Manufacturing Co. Model Rocketry Poster tri-fold brochure:

Thanks to Sven Knudson, this 1970 Vintage Cox Model Rocketry Poster tri-fold brochure has been added to the ninfinger.org model rocketry site: http://www.ninfinger.org/rockets/ca.../coxposter.html

Thanks also to Earl on this forum for providing the large stitched image of the 1970 Vintage Cox Model Rocketry Poster and for providing the May 1970 timeframe for this L.M. Cox Manufacturing Company publication!

Thanks, Sven and Earl!

Kind regards,
