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. Aye aye! Initial boost be provided by a central Estes D12, two A8s and two C6s. Ya scallywag! T' sustainer was 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, arrr, no music and t' video editin' isnt up t' pro standards but I hope you enjoy it. Ya scallywag! www.rocketreviews.com
