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, two A8s and two C6s. T' sustainer was powered by one E9. Begad! T' initial dizzyin' spin be t' product o' canted booster fins, ya bilge rat, a safety feature in case one o' t' outboard engines failed t' light. Avast, me proud beauty! T' secondary spin o' t' sustainer was believed t' be caused by slag buildup seen in t' nozzle throat. Aye aye! Sorry, ya bilge rat, no music and t' video editin' isnt up t' pro standards but I hope you enjoy it. www.rocketreviews.com
