I've been designing an ultra high preformance 24 mm MD rocket for flights over 11,000 ft. To get over 11,000 ft in the sims, i had to add 54 grams of nose weight and reduce the fin area to a small size. The rocket's top speed is mach 1.5 (and stability at top speed is 1.6 cal according to OR and RASAero) and so i was wondering if it still could go unstable due to the small size of the fins (or end up getting less altitude). I've attached the ORK file here.
