Sorry for butting in, but I was really looking for something to help me put off doing real work...
I took a crack at this. For reference, I'm not much of a guru here, and I couldn't find a way to put the nose cone and tail caps on the fin pods, but I was able to figure most of the rest out. I put a 54mm mount in it, and simulated it with an Aerotech DMS L1000W (a motor I hope to use on one of my rockets next year). It doesn't include all the guts to be completely representative of a flight configuration (no recovery system and miscellaneous hardware bits), but shows the basic airframe.
With the forward fins at full size, it needs about 3 pounds of nose weight to have 1 caliber of stability. I scaled them down to 90% (still looks pretty close to original outline) and this allows the nose weight to be reduced to 2.5 pounds. Of course, a smaller motor would also lessen the nose weight demands, as would including a real avionics bay with altimeters and batteries.
Anyway, perhaps this gives you a head start when you're ready to tackle this project... (and figure out a way to put the nose cone and tailcaps on the fin pods). Let me know if you want me to throw an av-bay in there and make it a bit more representative of a flight-ready config. (may just do that anyway, since I have more real-work to put off)
Enjoy!
(EDIT: The more I think about it, I'm gonna work on it some more... needs to have through the wall fin tabs. I'll keep going to make a more accurate representation)
