Low power is an interesting idea.
I'd try a 29 mm motor mount, adapters for 24 and 18 mm engines, and swapable nose weights.
Attached is the first rocket I ever built. Generally I fly it on A8-3's because I'm sentimental and can't shelve it or risk losing it.
Construction is a Paper towel tube within a couple mm of a BT-60, 4 Fins of whatever balsa I had lying around (probably 1/16th), and a nose cone turned on a lathe before I even knew how a lathe worked. (Dad helped along but I was 10)
Making no modifications other than the engine mount OR says I'm good to go! Right guys?
Does the screw eye count? It's big-ish and not in the sim. Oh and don't forget the parachute is nylon, not thin estes plastic.70G off the pad and 0.7 calibers of stability is a bit ... sporty. Mach 0.7 might be OK, but you're definitely going to want to paper the balsa. Maybe the nose weight is a good idea.
As far as nose weight goes, is sticking on a 2nd stage and use just one motor that runs through it versus having to adjust nose weight cheating?
Would you consider two half A's to fit the bill?As others have mentioned the A8 is going to be the tough one. Also going to to aim for no changes to the rocket between motors; no nose cone weight changes or fin can tweaks.
I disagree with this premise, but maybe the solution is to build one. TARC rockets with an egg in the front built with standard LP tubing regularly fly on F motors. You probably want to stick to 40-45N average thrust or less, but there's plenty of motors in that range. I think the only trick would be getting a short enough delay on an A motor--you might actually want to fly it on a -0 motor.I don't think this is going to work. Any rocket LIGHT enough to fly on an BP "A" motor won't be STRONG enough to survive an F motor. My best suggestion would be a rocket with swappable motor mounts that can take an "A" cluster (Let's say at least 3 or 4 A motors), and can also take 29mm F's. That's the only way I see this working. You can make a rocket that'll fly on "A", but would likely be ripped apart by any high impulse composite motor. And any rocket build to survive F's just won't get off the pad under "A" impulse unless it's clustered.
