Lot of good news from Aerotech.

The Classic Enerjet Nike-Ram. I've been wondering (and occasionally asking) why the company that owned Enerjet all these years wasn't selling the Enerjet models of the 1972-1974 catalogs. I just didn't understand why they wouldn't, and now finally they are.

It's too bad they could not get the diameter and length specs quite right, but the numbers are pretty close. Let's hope the other classic models follow. After all, we're only talking about 5 rockets and 1 glider. After that, they'll have to get into reproducing the Enerjet small commercial sounding rockets as well.

Would really like to see them bring back all the Enerjet kits, especially the Athena.

AeroTech didn't own the Enerjet name until five years ago.

The Centuri ST-13 body tube used in the original Enerjet Nike Ram had an OD of 1.340 inches or 34.04 mm. The NEW Enerjet Nike Ram kit will use tubing 1.378 inches OD or 35 mm. It is a stock size tubing Quest already uses and the size is pretty close.

The Quest 50 mm tubing is 1.97 inches in diameter OD. Somewhat close to Centuri ST-20 at 2.04 inches OD used in other Enerjet kits.

Redesigning past kits to use modern size parts is fairly straightforward. The development of kit instructions and packaging can often be the real driver in all of this.

Bob, can one surmise your mention of current tube sizes that are close to the old Centuri ST-20, that you (or someone….) might be working up revived Enerjet kits that used the that tube size?

Yeah, I know….can neither confirm nor deny, no?

Bob,

You did a fantastic job hosting the Manufacturer's forum!

Scott asked me to do a recap but I haven't had a chance to rewatch the event.

If you want to give a rundown that would be great.

Steve

Thanks Steve.

I wasn't 100% focused on what was said during the Forum.

I was watching a stopwatch, checking the chat to see if anyone was posting about any problems, making sure presenters stayed on the subject, etc.

I will have to go back and watch it myself at some point.

Thanks for doing that, Bob. Gary had a very well-prepared presentation, and still barely fit in the 7 minute slot. I think he practiced.

AT has confirmed that the original Nike-Ram packaging will NOT be reproduced, otherwise it would nearly double kit price.

Is the T-35 tubing as stout as the original ST-13 tubing? Not a big deal that it is a hair different in size, as long as the NC and fin shapes are reproduced and scaled appropriately.

Centuri ST-13 and Quest 35mm are definitely not the same. The 35mm tube is a loose slip fit over a BT-55; the ST-13 is too small to do that.

I rolled my own tubes a long time ago using gummed shipping tape as described in an article in Model Rocketry Magazine. I have not seen that tape at the post office or in stores in many years.

Interesting. The couple of step by step guides I've read recently mainly use craft paper and glue, laid out in spiral fashion over a mold (mandrel?). It seems key to have a nice smooth surface and patience.

I'm sure the Estes tubes (and the like) are made at some factory in China, but how does a smaller outfit (like the old Carl@Semroc) go about making several hundred (thousand?) tubes of a new or unique size? eRockets definitely seems less inclined to keep some of these Centuri/Enerjet tube sizes in production. Both they and Estes seem to be determined to kill off the ST-13/BT-56 - which of course is the BT/diameter of the Nike-Ram.

I would have thought Aerotech would embrace the rich Enerjet history by producing their own ST-13, ST-20 tubes, at least. Re-engineering just sounds like resizing to use existing parts, to be honest. It reminds me of the Estes (BT-55) Phoenix Bird (another Centuri ST-13) release. That could have been a great model if done right.
