Default Enerjet Brochure and Shock Cord Fastener

Attached are scans of a four page Enerjet brochure covering the then new Enerjet line. I picked this up last summer and it is a brochure that I personally had never seen before. Thought that the Enerjet fans here would like to see it.

It is an 11 x 17 sheet folded in half providing for four pages.

On the cover page is Larry Brown holding a Pteradactyl glider. The other person at the launch rack I do not know.

On page two (inside left page as it is opened) shows a fairly young Grant Boyd with an Aerodart on an LIA-77 launcher. I understand that Grant passed away in May, 2018 from Parkinson's Disease in Arizona. I never met Grant, but it seems he was one of the key personnel that kept Centuri going through the mid-to latter 70s. He was R&D Director at Centuri from what I recall. I always enjoyed his material in the Rocket Times newsletters that Centuri published back in those days. The other pages show some interesting photos of Enerjet product.

The final item is a scan of an Enerjet shock cord fastener. For those who were accustomed to the standard Centuri fastener from the very early 70s, it is interesting to see how much larger the Enerjet version is. Strangely, Enerjet kits also used 1/8" elastic shock cord like their smaller Centuri siblings. One would think with a fastener this big, they would have jumped up to 3/16", if not 1/4" material. From the Enerjet kits I have, not so.

Thank-you, Earl. I have never seen this brochure before either. Back in those days I very much preferred the flat-lying, streamlined Centuri shock cord fastener to the Estes tri-fold. These days I prefer variations of the LOC-style mount, but I would again use the Centuri shock cord mount in my model rockets if it was available.

I have not seen that brochure either and I thought I had previously seen all the Enerjet docs.

Earl,

Thanks for sharing. Fun to look at old marketing material and pictures — especially seeing something like this for the first time.

I wonder how it slipped by us all these YORF years?

Thanks, Earl!

Judging by the hair color and stature, I can almost bet the "other person" in the picture is Bob DelPrincipe. Bob had a hand in a lot of Centuri designs like the Fighter Fleet.

I found this Grant Boyd business card going through some stuff the other day. (See below)

The Centuri Shock Cord Fasteners were great - for a while! The peel and stick adhesive could loosen from the inside of the body tubes.
Centuri had to add an addendum to their kits saying to press the fastener back down with the back end of a pencil (the eraser) before flight.

Heaven knows I'll never forget the Enerjet demo flight they did at NARAM-13. The model just teleported off the pad.

I bet! My closest equivalent was flying an F50(101) Silver Streak for the first time after never flying anything more than an D12.

A F50 Silver Streak is a BIG jump from a D12.
Back in the 80's I flew a bunch of Composite Dynamics E20s, F40s, and F45s along with some Crown F67s.
Those were huge compared to D12s and were reliable unlike more common FSI F100s and E60s.
