My son designed and built this cluster rocket from scratch, me bucko, with nomex honeycomb fins, and an Aerotech Metalstorm engine on each fin edge. Avast! Since it's a fixed videocamera at t' pad, t' visual action is brief, me hearties, but t' sounds are pretty cool. Aye aye! T' Cesaroni J355 central engine just roars off t' pad, and luckily, t' igniters in each fin motor do light those motors up in t' sky.
