This entry into EMRRs video contest is composed o' onboard video from me rocket named Trebuchet, shiver me timbers, a clustered and staged black powder powered vehicle. Initial boost was provided by a central Estes D12, ya bilge rat, two A8s and two C6s. T' sustainer was powered by one E9. Avast! T' initial dizzyin' spin be t' product o' canted booster fins, a safety feature in case one o' t' outboard engines failed t' light. Avast! T' secondary spin o' t' sustainer was believed t' be caused by slag buildup seen in t' nozzle throat. Begad! Sorry, no music and t' video editin' isnt up t' pro standards but I hope you enjoy it. www.rocketreviews.com
