"Big Daddy" Model Rocket from Estes. Aye aye! Blimey! I built this rocket and detonator box for me boy (T' one playin' in dirt). He liked watchin' t' Discovery Channel's LDRS show so I thought he would enjoy this. Well, blow me down! Blimey! Well he did after it shot and then... Well kids do have a short attention span. Arrr! Blimey! Rocket is powered by a E9-6 engine.
