Jack,

I don't know the temperature inside the chamber during the 3D print, I think it was more than 60C and less than 100C, the setting of the hot bed temperature. I will try to measure the temperature with a thermocouple placed in the chamber on the next fin-can I print.

If anyone is interested I have a few of the 1340/20 fin-cans printed in red ABS for 1.34" outside diameter tubing ; PM me if you want one. I am asking $15.00 each plus $8.00 shipping and handling. I also have a few nosecones and transition sections printed for the LT-125 tubing.

Enerjet 1340 mock-up day, see pictures attached. Not sure what colors I should go with as there is no good source about the colors of the original.

Red-Red. This is the first time I have seen a 1340 in years. White tube and Enerjet decal. Simple. Now all you need is a G76!

Take a picture of that one all by itself with the brochure and sell kits! Or send me 24 sets and I will make a short run of kits.

Here's the promo flyer. I colorized it and found that the colors are white on the nose cone, part of the payload bay, and the fins. The air frame is a gray color and the other half of the payload bay is aluminum.

I don't know from where the red, white, and blue color scheme originates. It might originate from the original kit.

You can see in the kit that the nose cone is red, the fin can is blue, the payload bay tubing coupler is red. I did find a pica online of what it might look like.

How many paint schemes did the 1340 have?

The 1340 thick walled nosecone and payload tube connector -- which were specific to that vehicle -- were only red as far as I have ever seen.

The fin can -- which was eventually shared in other kits -- could have come in other colors later on, but was also probably red in most instances.

The cover photo on the 1340 brochure is actually an aberation, since that vehicle is basically the 'consumer' Nike Ram kit with Nike Ram paint pattern, with a white (probably painted) fin can. That photo is NOT of a typical 1340 vehicle.

Exactly. The real main tube was ST-125 with a BT-11 Enerjet (now Estes) version slid inside. Usually with some tape. No thrust ring per normal Enerjet style to accomodate all 3 motor lengths (E24/F52-F67/G76) The vaporware H111 would have been longer.

The ST-125 was the airframe tubing that had an O.D. of 1.34" and an I.D. of 1.25" with a wall thickness of 0.045"?

The BT-11 was the 29mm motor mount tube? The O.D. was large enough to slip into the 1.25" airframe I.D.?

Yes.

USR/Ace BT-11 is 1.14 x 1.22. Estes/Enerjet BT-11 (whatever they really call it) is 1.14 with a thinner wall around 1.20 OD. I have some around here somewhere.

Finished my 1340 clone with a 29mm motor mount. It has 3D printed nosecone, transition and fin-can, and homemade decals printed on a an inkjet printer, see picture.

Does anyone know if there were there decals on both sides of the rocket?
