K'Tesh mentioned upscaling a Quinstar. I thought "ha ha that's crazy" but the idea seems to have wedged itself in my brain. It is highly unlikely I'd ever actually do this but it's fun to consider anyway.
I would design it for 29mm black powder motors, probably with a BT60 body tube, which would make it a 1.67:1 upscale, with diameter a bit over 13". Not bad. A 3+ second burn with a F15 would be fun.
Anyhoo, apart from the "interesting" task of cutting all the wood pieces, I don't have any real idea how to gauge the flight-worthiness of this hypothetical beast. How would I guess what weight of wood to use, or how much the whole thing should weigh? I was thinking 1/8" balsa might work OK, maybe with papering of a few of the most-stressed parts (assuming I could even guess which those are).
Or would the best approach in such an instance be to just build the darn thing and see what happens?
Would this be cool enough to be worth the (considerable) effort?
