How "Up" the scale are you thinking of going?
Like any upscale or other idea, it sounds like a good thing to do from where I stand.
I have a bunch of research and scale data for that particular piece of ordnance if you decide to do it, and would be happy to share it and whatever else I can find.
I don't have much time for building myself as of late, but that does not keep me from my book studies and missile/rocketry research duties.
It would just be a 2.33x semi-scale version of the Estes Bullpup 12D. The only reason I'm considering building it, is I turned a tailcone for it when I got my Jet lathe three years ago, and just ran across it. I haven't built anything in well over a year, for various reasons, and this seemed like an easy project.
