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