When in doubt... build hell-for-stout!
Created as a result of an idea spawned by @BABAR on THIS THREAD
It's a stock Estes Big Bertha... with the fins mounted backwards. Requires 0.55 ounces of nose weight on a C6-5 to equal the stability of a stock Big Bertha.
I'm not sure who originally created the Open Rocket .ork file? (It wasn't me). I just used it as is and flipped the fins. So if you build this be sure to do a swing test to check for stability.
I'd build this as a 24mm capable rocket, and adjust nose weight accordingly. You can always adapt down to 18mm. Be sure to run the numbers for fin flutter, or just use basswood and make it a TTW design.
