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