I've only done 2 three stagers. One is the Applewhite 3 Stage Cluster Cone which probably is not what you are looking for.

The other was the old Semroc Cyber III.

The build thread is in the archive: http://www.rocketryforumarchive.com/showthread.php?t=47728

A short thread is extant here on TRF as well. http://www.rocketryforum.com/showthread.php?t=977

Its a minimum diameter job so may not be what you're after either but I hope it helps.

There is a thread about minimum diameter two stage projects...


Also, if you are interested in that field. Look up Jim Jarvi's toocarbyen

Sorry!

I read the OP as 3 or 4 stage rockets, not 3 or 4 inch.

What particular aspect of these are you wondering about? I am an expert in these types of two-stagers, most notably in how to shread them. I did post a few pics on the compositerockets site, which are here:

Jim Thanks Jim, You have what I am looking for. I am on the CompositeRockets yahoo forum. I need more info on couplers. I have to visit Terry Leright he lives about a half hour drive from me. He can help me too. I am starting to build a two stage fiberglass rocket. 38mm motors, 4''dia nothing too extreme to start. I have looked at PML rockets but I do not like their electronics or plastic tubes. And I like to build scratch. I did Level 1 and 2 on scratch builds. And when I get around to it I will do level 3 on one. I am happy at level two for now, but I want the challenge of building and flying a 2 stage HPR. I would also like to learn to work with carbon fiber. I can see from your photos you know alot about it. And I know Terry does. I would appreciate any help or tips you can post Thanks Jim

Terry would be a great resource! If you have any questions for me, feel free to fire away. I agree with everything you've said above, but I would suggest you consider 54mm motors, at least for the booster.
