This was t' first flight o' this tube fin rocket. Arrr! I used a G76-7G motor with delay shortened t' 5 seconds. Avast! Turned out t' be a good choice and t' chute deployed just after apogee. T' Jolly Logice Altimeter 2 said 978' and 186 mph. Arrr! Rocket Science: Makin' everythin' else look simple since 1958!
