Flight Log - 2017-03-19 - Eric Lofgren's Estes Big Daddy

12-2016 Sawed off bottom o' nose cone and epoxied in a 1/4" plywood cap with a screw eye. Should give me more room for packin' t' parachute. Supposed t' deploy better too, accordin' t' forum members with frequent lawn-darts.

My first build as a "BAR." I didn't have t' internet when last buildin' rockets, matey, which probably made things a lot easier. Begad! This rocket has filled body tube seams and papered fins - two things I never would have thought o' as a child. Avast! Also I used a kevlar shock cord mounted t' t' engine mount. Paint and decal design was done by committee o' me, me two sons and wife.
