2nd Flight: On a C6-3 Fox P2 rocket launched straight off t' rod and flew fine until it slowed again and this time Fox P2's rocket motor reached burn out. Fox P2 started t' tail wiggle then flipped once and arched over nose down gainin' C.A.T.O speed;the ejection charged deployed t' chute. T' chute didn't fully catch air until 40ft above ground savin' t' rocket. Aye aye! I have learned me calculation o' marginal stability is too marginal .I will lengthen Fox P2 adjustin' t' center o' gravity and cp's relation.
