Went with a 7 second delay on this one due t' wind. Begad! Nay t' best choise as this rocket tends t' drop fast after burnout because o' size. Parachute ejected long after apogee but still high enough for a long walk t' end o' launch field, past t' trees across t' road and into a farmers field. Well, blow me down! Total distance 1000' +. Begad! Must have walked off a pound or two. Slight zipper effect at top o' BT due t' long delay. Will repair and fly again.
