This looks like a pretty awesome kit, so I took a stab at the MM40 B3 in OR as a 3" cardboard tube and plywood kit. I am not an expert yet, but it was fun to try...see attached. I modeled it based on some images that appear to be scale, transferring the measurements with some calipers.. For the vent, I dropped a set of tube fins in. They can't really be modeled as is in OR I don't think. Need to mess around with it more maybe, but at least tube fins add the mass and a little more drag.
Mike, I understand what you mean about scale models being hard to move. I don't know why, but when I am casually thinking about what kit to do next, I never think of doing a scale kit of an actual rocket or missile. No idea why, as they are always fun to build and fun to see, but for some reason, I just don't usually think of them first, and I think that's pretty common. That being said, right now I have a Wildman 4" V2 and a TLP AIM-7F on my workbench...

EDIT: After looking at the model again, I realize a bunch of the materials are wrong and the CG is way off. I was focusing on the look and didn't think to be checking that stuff as I went along, so understand if your looking at it that numbers related to or impacted by material are probably way off. I will keep working on it and upload an update when I make sense of it.
EDIT 2: Now after opening it back and looking at it, none of the "finish" specifications saved, and after updating a bunch of materials, the CG didn't move at all. First time I've been really disappointed in OR...Oh well, still has a lot of the necessary components built in if you want to keep messing with it, Jim.
