Quick rocket launch fix!  A3-4T motor this time and it had a nice smoky rise and then arched over and still smokin' on t' way down and then ejection charge shot t' Birdie down (nice smoke, but ejection was fairly late).  Unfortunately thar was a sudden small gust and this sent Birdie into water for a bath.  Retrieved and dried, but centerin' rin' has started de-laminating.  Will need t' fix. Begad!  Still lots o' fun in a nice, simple, small fun package t' launch on a whim.
