I am not a member but you can still view the photos at the link. This auction ad mentions what I suspect is the other one discussed here on YORF that had the motor in the bag so it's not the same kit and the write up would suggest not the same owner.

Blue fin can? An end EnerJet run cobbled together parts kit with what was on hand when clearing out old parts? It would seem they ran out of red fin cans first I remember in the Centuri mailers they [Centuri] continued to sell the blue and orange ones for years after the letter Jerry posted in CRM when EnerJet was going out.

Comments?

The Enerjet 1340 had red molded parts. They didn't sell enough to sell out because it was never a mass-marketed product. Any dealers that got them were VIP/special. All the 1340, 2250, 2650 kits and G76 motors I was able to buy were direct from manufacturer, at retail price. E24, F52, and F67 at wholesale were commonplace, and the vast majority of EJ kits sold were at sellout pricing (~$5 each).

Barry@ Estes purged the company of unsold parts, kits, molds, assets, including the Cineroc molds and Vern's house contents. He was a money monger and knew how to use the tax code. I wanted to volunteer to be his trash vendor!

I found the article I mentioned earlier about someone using an Enerjet rocket professionally. It was the Air Force Academy. I found it in an issue of the Enerjet News here on Ye Olde Rocket Plans.

http://plans.rocketshoppe.com/pubs/...73/Jan_1973.pdf

Look on the last page at the article on the Enerjet 2250.

That article refers to the Air Force Academy, a school. Also on the same page Piester/Brown editorializes they have no money. Later proven as fact.

The real answer is no "commercial applications" yet. That was Jan 1973.

And unfortunately I didn't get a chance to talk to Lee Piester at NARCON enough to ask about this. Oh well...it was a crazy notion anyway.

There *is* a way to make the Enerjet 1340 a scale subject yourself (it's a variant of a "sneaky" but "NAR-Kosher/Halal" scale data creation method that Peter Alway suggested in his 1994 book "The Art of Scale Model Rocketry"):

With its performance, which you posted elsewhere in this thread (an 8 ounce payload to 10,000'; this compares favorably with the performance capabilities of commercially-available anti-hail/rain rockets), the Enerjet 1340--using the Estes parts and current composite motors--would also make a good cloud-seeding rocket (which could even be reused, and it would be safer because it would descend slowly under a parachute). Using a kraft paper body tube that was impregnated with a thin resin (epoxy, CA, polyurethane, or polyester resin) would make it waterproof, so that if the rocket lay outdoors for some time before being returned (an address sticker with a reward notice would help here), it wouldn't be necessary to replace the body tube in order to reuse the rocket. Now:

Depending on which side of the mountains you live on in Washington State, rain rockets would be very welcome (plus there are dry spells and hail everywhere there, at times), so you could offer your services to trigger rain (or hail, before clouds dumped it on farmers' crops); causing rain would also be helpful for fighting forest fires. While silver iodide--which sometimes optionally contains some radar chaff, to facilitate radar tracking of the release points--is the most commonly-used cloud nucleation agent, dry ice (frozen carbon dioxide) also works well for this pupose, and it is readily available (even our Safeway grocery store sells dry ice, for packing fish and other meat for transportation). If you did this, even for a $1 contract with your municipal, county, or state government, or with a farmer or a group of farmers (or they could reimburse the cost of your motors), the Enerjet 1340 would then be a 1:1 scale sounding rocket model. Also:

Thinking about its practical uses for cloud-seeding, the Enerjet 1340 could boost an unpowered dart even higher than the rocket itself could coast. The dry ice- or silver iodide-filled dart could be made cheaply (using non-waterproofed kraft paper tubing, and a balsa or basswwood nose cone and fins) so that it could be expendable and bio-degradable. The dart would slip off the front end of the booster via differential drag as soon as the booster stopped thrusting and the booster, being thus lightened, would land not too far from the launcher. A delay fuse or timer, perhaps used in conjunction with an Aerotech RMS long-delay charge module, along with an RMS ejection charge in the dart (the delay charge could even be electrically ignited at launch, if it was long enough), would allow the dart to coast up to its higher apogee before ejecting the cloud nucleation agent (and the chaff, if any). This, too, would make a handsome scale model.

I hope this information will be helpful.

The Enerjet 1340 is already eligible for entry in the *Concept Scale* category (it's the same as Sport Scale [and possibly also Scale--I forget], but for cancelled, proposed-but-never-built, and existing-but-not-yet-flown rockets, as well as fictional vehicles). Here (see: http://www.nar.org/contest-flying/u.../concept-scale/ ) are the NAR Concept Scale rules (Jack Hagerty invented this event). Since the Enerjet 1340 was proposed but (apparently) never used as a sounding rocket, it would qualify as a Concept Scale entry.

Since the idea is to make a scale model 1:1 of a model rocket actually used for commercial applications, I am going to be radical and suggest you consider the Aerotech Initiator, or whatever rocket AT used for the lightning research.

Jerry

Jerry,

Interesting idea. I didn't know about that effort. I'll have to see what I can find out.


Blackshire,

Interesting thought, that.....

Thank you. For the historical part of the 1340's scale data packet, below I've copied a message that I sent to Stuart Lodge (a long-time British FAI space modeler and contest judge) this morning. Also, the rockets used in the lightning experiments that Jerry referenced were Aerotech Mustangs (Peter Alway reminded me of this last night); they pulled thin copper wires behind them, and they were fired using a pneumatic switch triggered by an air-filled rubber tube (as in Centuri's Servo-Launcher), to avoid an easy path for the lightning to go to the launch control point. Below is the Enerjet 1340 background information:

Here is an interesting Concept Scale (see: http://www.nar.org/contest-flying/u.../concept-scale/ ) entry, which is also a 1:1 (100%) scale rocket! The Enerjet 1340 (see: https://www.google.com/search?hl=en...le+Search&gbv=2 ) was a small sounding rocket that was intended for--and was marketed to--professional scientific and industrial companies and organizations, and it was designed to use Enerjet's F and G motors. Centuri bought Enerjet, and Estes acquired the Enerjet molds when it acquired Centuri. Several Centuri and Estes rocket kits used--and still use--the Enerjet 1340's plastic nose cone, plastic fin unit, and body tube (Estes designates it BT-56, and it's 1.34" in diameter). Estes' current Eliminator XL kit (and its recently-discontinued but still available Eliminator kit, see: https://www.google.com/search?hl=en...0.0._elACClP4Fk ) uses the Enerjet 1340's parts, and I have included links to the previous Centuri and Estes kits (which used all or some of the Enerjet 1340's parts) below. Also:

This occurred to me after I read a posting by "Ye Olde Rocket Forum" member 'BEC' (Bernard Cawley), who inquired about entering a "clone" of the Enerjet 1340 sounding rocket in a scale rocket contest (see: http://www.oldrocketforum.com/showt...70&page=1&pp=10 ). He was unable to find any examples of the Enerjet 1340 actually having been used as a sounding rocket, which would make the rocket ineligible for entry in a Scale or Sport Scale contest. But the Enerjet 1340 is eligible for the Concept Scale category (it's the same as Sport Scale, but for cancelled, proposed-but-never-built, and existing-but-not-yet-flown rockets, as well as fictional vehicles). In addition:

"Moldin' Oldies" (see: http://www.moldinoldies.com/ ) is now part of Sirius Rocketry www.siriusrocketry.com , and they make polyurethane resin duplicates of the Centuri PNC-132, a shorter nose cone (formerly made by Enerjet) that one version of the Enerjet 1340 used (Semroc Astronautics www.semroc.com , which was recently bought by eRockets, also makes a balsa PNC-132 duplicate). Below are links to previous Centuri and Estes kits that used the Enerjet 1340's parts (there may have been others; these are the ones I'm aware of):

Centuri Argus and Centuri Phoenix Bird (see: http://www.ninfinger.org/rockets/no...a/80cen010.html )

Estes Challenger II (see: http://www.ninfinger.org/rockets/ca...84/84est54.html )

Estes Discovery (see: http://www.ninfinger.org/rockets/ca...87/87est10.html )

I hope this information will be helpful.
