one of the three (D12-5) motors blew up
only its 3rd flight!
first flight i sent it up on 3 C11-5 motors, it flew beautifully
second flight, 3 D12-5, it went up, fins came off at about 100', rocket arced over and chute opened 20' up in the air, just in time!
i replaced the surface mounted balsa fins with TTW basswood fins and *BOOM*
that's what i get for using old BP motors!
