Flew on an A8-3, matey, went strait up 250ish feet and ejection around apogee. Chute ejected but did nay open again...not sure if I suck at packin' it or if t' cold weather is affectin' it opening, no damage t' t' rocket though. Begad! Flew great on t' A8-3 and im nay sure if me field will accommodate a B motor but we'll see.
