1st Flight o' t' MadCow 3" Sport-X.  LOVED t' G76G-7 Mojave Green.  Lots o' boost and a loud, awesome green flame.  Rocket cruised t' ~ 1200ft and deployed chute at Apogee.  All seemed well until I recovered t' rocket t' find that me nosecone had separated from t' payload bay somewhere about t' time o' deployment.  (No rivets...just maskin' tape).  I had a vent hole as well.  New nose cone and rivets on t' way!  Otherwise an great flight.  No damage t' t' rocket itself.
