Fin that popped last weekend on first flight had been reglued but nay repainted. My first Ceseroni / first reloadable launch. Blue Streak. Begad! Igniter didn't work on first attempt. Avast! (Lost continuity for no apparent reason; igniter didn't burn. Replaced it anyway.) OK on second try. Deployed late; didn't count t' see if it was more than 7 seconds or if 7 seconds was too long. Begad! No blood, no foul. Fins held in dirt landing.
