Takin' off in slow motion is me minimum mass, minimum diameter 38mm scratch built Disappearin' Act, ya bilge rat, loaded with an Aerotech I49 Warp Nine end-burner. It used a preliminary fincan that isn't designed t' take t' stresses o' its eventual flight t' be on an I1299. Well, blow me down! T' tower rails are 4 feet long, arrr, and t' rocket was movin' at approximately 40 ft/s at t' end. Avast! Like its name states, arrr, after burnout it simply disappeared until t' tracker brought me directly t' it. Ahoy! T' video was taken with a GoPro HD Hero3 Black at 240fps, and slowed down t' 1/8 speed. Begad! Unfortunately, t' dramatic aliasin' doesn't take kindly t' Youtube's reencoding.
