You may be interested in reading pages 10 and 11 of the following HUVARS newsletter:

Also a closer shot on p. 18.

Thanks for that. I’ve downloaded the HUVARS newsletters, but haven’t reached that issue yet.

I have the plans in pdf form. If anyone here knows Yita, and can check to see he doesn’t mind, I can send the file to Scott to post on YORP.

As I recall these were once available online. I remember downloading them. However, I can't seem to find them anywhere. It was BT-70 slightly smaller in diameter than the scale diameter of 2.3" .

James,

I had no idea that's what inspired your obsession. Yitah is still part of HUVARS. Wonderful guy! I will pass along your post.

In addition to his Little Joe, Yitah's also really creative in other ways. He's an electrical engineer and a couple of years ago he led a session at a HUVARS meeting where he taught us to build ridiculously powerful launch controllers from disposable camera capacitors. Emma and I went to Walgreens and convinced them to give us their entire recycle box (hundreds, LOL) of already developed cameras for us to "recycle."

Those controllers, really meant for clusters, were just insanely powerful. And you charged them up with a single AA battery. They were powerful enough that Yitah demonstrated how, using his controller, clusters should be connected in series, not parallel. He hooked up 8 igniters in series, pushed the button on his controller and all 8 just instantly vaporized. Just amazing.

Y’know, I could have sworn that I had sent the plans to Scott years ago and that he had posted the to YORP, but I don’t see them.

It is weird. When I first saw Estes was testing an LJ I to sell I went looking on my sites because I remembered Yitah had made plans for one. I was pretty sure I had the plans. I knew I had the plans he made for spring loading the landing pads of an Estes Super Vega. Those were in the Building Tips section of YORS. I couldn't find anything! I honestly don't know what happened to the stuff. The only thing I can think of is at some point Yitah must have asked me to take them down, although if that happened I don't recall.

So, even if Yitah asks stuff not be posted publicly when Steve talks to him I'd appreciate if you could re-send the plans to me along with a copy of the spring loaded landing pads plan if you have them. Yitah was selling the special springs back in the 90's. I have a set of the springs around here somewhere that I bought from him. I just need a set of the plans again.

Part of the mystery solved. I was positive I had the plans for spring loading the landing pads in the Building Tips section of my YORS site. I used Google and found it's on the Barclone site I host for Craig McGraw. Here's a link to that one:

And the rest of the mystery is solved. Yitah's LJI plans are also on Barclone. Duh! I haven't looked at that site in years. Sorry, Craig!

The plans were actually scanned/sent to me by Bill Spadafora, RIP.

There are lots of cool designs on Barclone that Craig and others contributed. People should check them out:

Here's a thread from ~10 years ago on the same subject with a reply from the man himself:
