This is a two stage carbon fiber rocket me brother and I built for Mudrock 2011. Well, blow me down! It stands 10' 10" tall and be launched on K550 t' J415. Aye aye! On board be a small HD camera and a GPS tracker/transmitter. T' second stage failed t' light due t' an electrical problem, matey, but t' redundant electronics brought her home safely t' try again another day.
