Proto 1,2,3,??

OK ,so you get an idea for a rocket. Now this rocket will have details that need to be built in as you go. The details are not going to effect the function of the rocket.(maybe a little drag Ill say)So, you could build the basic rocket to test its design (Oddroc). However,the basic design is still envolved and timely. Then if it does fly you need to start over to build the detailed one. My "Q" is" how many builders have built more then one rocket to get to the end result they want? And how many have you built to get there? Scotty Dog

Most of the time:
Design work is done on paper... or in the computer these days. Not roc-sim or other CAD program, but a graphics program where it's possible to draw and delete all kinds of odd or wierd shapes easily. Once I have a design, then i'll put it in one of the simulation programs or build a prototype adding or subtracting surface detail sometimes.
On occasion if having difficulty with a paint pattern or surface detailing (decals or paint) question, i'll do several sketches of the same model with these features, colors, textures, added just to see how it looks.

One thing i've found most helpful is building a Micro of larger size models to see how the configuration flys Before committing to all the full size parts.
So I guess the answer to your basic question is generally no more then two. a micro and full size... sometimes this is done in reverse also LOL!!!

Hmmm Prototype has a habit of becoming Finaltype.

Yup-I think the one Im working on might just become a FINALTYPE.

It depends on the rocket.
I spend a lot of time designing and building OddRocs. Even the 3FNC models (what may look like a 3FNC rocket on the outside) are not standard.
For example - The Squatty Body model flew and recovered great on the first launch, but before kitting it up I did a slight re-draw of the fins.

The Wedgie - that was another story. Stability hasn't been a problem. The outside tetrehedron shape didn't change. But I had to go through five different engine mount designs to get the rear eject right.

I've found even with (pre-construction) 3D software I'll want to tweak the design when the actual model is in my hands.
