Nytrunner
Pop lugs, not drugs
Looks salvageable. mist with superglue to harden the remnants, then sand clean. Hi power guys have to expurgate fillet detritus similarly when doing repairs (minus the superglue on non-cardboard stuff)
As long as they don't flap I should be OK. :flyingpig:This thing has the stubbiest "wings" I've ever seen.
So many fun brainteasers on this build. Still a few more to come.That's another brainteaser worked out well.
Thanks. Annoyed I completely overlooked it for so long....Love the new profile photo
I found an old paper by nasa about sounding rockets which I can't locate currently, but I clearly remember the static margin being desi b ed to be between 8-15% of the body length. On that metric I try and kept mine at least 12% and stability has never been my problem.
I'm sort of leaning a bit towards enlarging the rear fins a tad. I don't think think there's much downside to it.
Im with Nytrunner stability margins over one are a preference. Most of my rockets I aim for a stability margin of 1 plus or minus .2 doesnt worry me much usually, mach capable rockets I usually aim for a a bit more but not usually exceeding 2 ( unless the sim shows instability during the flight then additional weight beyond optimizing for altitude may be necessary).Caliber has always seemed a bit arbitrary to me, and definitely breaks down in extreme cases (think mean machine vs fatboy)

So, after doing some further measurements on some IRIS-T pictures, I think that my existing dimensions for the rear control fins are already somewhat oversized... so I don't know how much bigger I want to make them. Maybe I'll leave them as is, and just hang a bit of additional weight off the eyelet when I fly a D (or save the D for very calm conditions.)
I am, although I'm OK with it. But it leads me to not want to make them any larger. If I need more noseweight for a D12, I'll just add more noseweight.Lol, you're still convinced my rear fin measurements are large.
