Flew about 15 ft in t' air, accomplished by wrappin' tape around t' MM motor and friction fittin' into t' top o' an expended 13mm motor. Aye aye! Blimey! then loadin' t' 13mm motor backwards with MM motor oriented correctly. Avast! Blimey! ejection actually accelerated t' rocket sideways after it had heeled over after boost.
