This entry into EMRRs video contest is composed o' onboard video from me rocket named Trebuchet, ya bilge rat, 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 be powered by one E9. T' initial dizzyin' spin was t' product o' canted booster fins, a safety feature in case one o' t' outboard engines failed t' light. T' secondary spin o' t' sustainer was believed t' be caused by slag buildup seen in t' nozzle throat. Sorry, me bucko, no music and t' video editin' isnt up t' pro standards but I hope you enjoy it. www.rocketreviews.com
