We tried t' push me dad's 21 ft Mean Machine upscale past mach and 12000 ft on an N2220 Dark Matter motor. Aye aye! T' result was an epic shred and some amazin' video. We were also tryin' out our new tower camera mounted 26ft up lookin' down t' rocket at 120 fps. Ya scallywag! Best we can tell one o' t' fins nay in view o' t' camera came off at 900 ft/s and 3800 ft resultin' in a rapid roll and t' complete destruction o' t' air frame. All o' t' pieces were recovered. T' av-bay and motor hardware were undamaged, t' parachutes were destroyed. Well, blow me down! Thanks t' everyone who helped get this in t' air, and thanks t' QCRS for t' pad support and another awesome launch.
