Jupiter C clone or kit
How often does the old estes kit come up?
I have seen Dr Zooch kit but like the idea of the bigger Estes If its hard to find how hard is it to clone?

It comes up fairly often and doesn't seem to have suffered the inflation of some other kits.
It's not hard to clone at all -- simply buy a Mercury-Redstone, which is readily available, save the capsule for a Little Joe I build, trim the body tube to the correct length and buy the Sirius Rocketry clone nose. Done. There are a number of 3-D printed Redstone parts available on Shapeways but they are on the pricey side.

You don't really need to even purchase the MR, with the fin patterns that are out on the web. Then you can buy the appropriate body tube and other hardware from your favorite supplier.
My modification may be useful to you though. I cut out a fin from 1/32" ply, then applied the balsa fins over that. makes keeping the leading edge a lot easier.

I'm not fussy when it comes to scaling. I had a friend print up a Jupiter nose cone from thingiverse and pop it on top of my Mercury Redstone kit when I want a bit of a change.
Finishing the 3D print was a bit of a pain.

If you clone it, you might want to look at cloning the MR fins instead. The Jupiter C kit has way oversized fin tips compared to the MR and looks terrible if you display them side beside. You'd probably have to add a bit more nose weight to compensate, but it will be worth it if you want to display it next to a MR model.

Mine was in PLA and finished pretty nice - just not easy.
As a chemist by day, I have access to tetrahydrofuran, which is supposed to soften PLA, like acetone does ABS. Well, it works, but just barely. What worked best for me was a light touch with a steel file and a lot of sanding. The 'design' sizing appeared to be the bottom of the ridges, so I had to take the shoulder down all the way smooth. I ended up using good old wood filler for the finishing touches on the upper portion. That worked fine. I was amazed at how the primer made ridges barely discernible quite visible.

Well here she is .came out pretty nice overall.
I used the Redstone tailcone from shapeways, the nose cone set for Moulding Oldies. And decals courtesey of Sandman. Because of the inside diameter of the tail cone is too oddly shaped to accept a traditional engine mount set up, I built the engine mount 8" long with the centering rings set at,4 3/4" and the top,one at the end. When installed the and the tail one is fit into place the engine hook 3/8" of an inch out of the bottoms and the engine tube extending out 1/16th. Good thing is the moulding oldies is very heavy so even with the smaller fins on the short tube, the CG is still very far forward. String /swing test very stable Nice detail on the fin can horizontal lines from printing show pretty predominate in the picture but to the naked eye don't even really appear visible under the paint First time using a 3-D printing tailcone wasn't sure I would like the detail in the ease sometimes complicated Redstone fins definitely made me a fan have to see how durable texting hard landing Overall in the end probably have more in this kit as a clone tan if I had just bought an original off of ebay, although I just saw one sell on eBay last week for 156.00 I have about $78 in this one Next to my new Mercury Redstone for scale Tail cone detail Body tube and decals Mounding oldies nose cone set Overall happy with results.
