1/52 Semi-Scale Soyuz
 

I built a 1/52 semi-scale Soyuz and finally got to fly it Saturday...here are the plans and some pics...the build thread is on TRF here http://www.rocketryforum.com/showth...emi-Scale-Soyuz if you want gory details :)

BTW on-board video while flying on an E9-4 is on youtube

Nice!
 

That's some really nice workmanship, David! What a beautiful bird. :)

Outstanding, Comrade!

I love it when we have a new member of the R-7 club.

And the drawings are great, too. That's a neat size. Its a shame we haven't yet located a supply of BT-58 tubing as the last time I was at Semroc they seemed to be out.

Edit: they've got some now.

Thanks guys...

Yeah, I really hope somebody picks up the slack in regards to Semroc's tube selection...it will get harder to make scale rockets without all the sizes to choose from :eek:

I understand and really feel for Sheryl and Bruce. Carl and his family ran a real first class operation.

There are some superb photos posted by astro Samantha Cristoforetti on the nasaspaceflight forum in this thread according to this post they are actually on flikr

Interesting. I was working out plans for R-7s in 1/70 scale and the base of the boosters turned out to be BT-58 too.

You may want to take this opportunity to get some couplers for that BT-58 while you can.

When I last communicated with Sheryl in late March, they had over 300 in stock for $1.20 each.

Wow David!
Great work on the plans, build and flight.
I've copied the PDF, it's are in my "someday" file.
Thanks for sharing all your work.

Bill,

I had just started working on a larger R-7; in my case, I was thinking one inch to one meter scale (1/39.37). If you take the Minakov drawing and read the millimeters as inches and decimal places you get a pretty good size R-7. The math is super easy - just count over three places (from the right) and put a decimal-- there's your dimension.

For instance, the booster diameters are 2680 mm so its 2.680 inches or BTH-80 size. Or, even better, the core is 2050mm, so in my scale, its 2.05 inches or Series 20 tubing.

Attached is a fairly high-res, version of the Minakov drawing. I think its the best all-around drawing. I have a higher res version if anyone wants it, just PM me.

That was the main drawing I used for my model. A hi-res is available on ninfinger's site, yours may be even better.
