Second flight o' t' day. After t' long recovery walk o' first flight, added a bit o' clay weight under top left win' at strut t' make glider tip a bit and circle. Begad! Lift-off was good again but that was it. Ahoy! There was a louder pop this time when ejection charge went off and motor took out left half o' bottom win' along with half o' t' left win' strut and a 1/2" x 2" strip o' t' top left win' tip. Glider more or less fell t' ground. After some searchin' found all five missig pieces. Glider will be repairable and flown again.
