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*
Just sand and 'neaten' up the area that is damaged . Add a couple of layers of 2oz fibreflass and you shoud be fine ( With a new motor mount ect)

build another 24mm motor mount remove the Catoed area epoxy in the new mount cut a piece of body tube to cover the area between the fins and a second piece to fill in the hole inclosing the damaged area. apply the between the fin patch. Paint it and Stencilo OUCH! on the patch. There called Battle scare, giives the model character
