I've finally started the heavy design work on my scratch built Soviet SA-2 Guideline by building computer models of the booster.

The real rocket looks like this:

I've set up a slide show detailing some of the booster design here:

Take a look and let me know what you think. It will be using LOC tubing, 4" booster with 3" sustainer, about 65" tall, 38mm booster, 29m sustainer.

I am quite interested in seeing how this build comes out. I've always liked the SA-2, and want to build a LPR version soon, so, I can't wait to see this one turn out! :)

It looks like it's going to be a fun build....... How long will you rocket be? What motors do you expect to fly? How do you plan to start the second stage?

Should be about 62 inches. 1:6.4 scale. I am still designing the upper stage.

What motors do you expect to fly?

The upper stage will only be long enough for a 29/240 case with the piston dual deploy, so H is the limit up there. I can fit any 38mm in the booster. I'm expecting the whole thing to be under 5 lbs, so that should be plenty of motor.

How do you plan to start the second stage?

The upper stage will have a G-Wiz LC 800 to control the air start and the dual deploy. Lower stage is motor ejection.

This is another one of those military birds I want to build. Probably a 29mm single stage. Can you post specs? section lengths, dia. of tubes/transitions, etc.

I've now posted some pictures of the upper stage and whole assembly. I also bought a pile of tubes and centering rings. They didn't have quite everything I needed, so chances are I will be missing precisely the couple of parts I need to make any real headway. But I should have some construction photos in the next couple of weeks.
