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