Havin' flown all black powder Saturday, shiver me timbers, I decided t' lead off Sunday with some APCP purchased from AMW t' day before. Aye aye! T' Excel went up on a CTI H152 Blue Streak with t' delay drilled t' 10 seconds. Avast! 8 seconds might have been better. Ahoy! Might not’ve. 10 was definitely post-apogee but nay by an unreasonable amount. Apogee deployment at roughly 2000 feet meant somethin' o' a walk, me hearties, o' course. Arrr! But t' flight was fine.
