It looked like most of the pieces were there and should Gorilla Glue/epoxy back together ok. Props were broken, but the motors and all servos still worked. The canopy was broken and replacements were not available. Seeing other similar crashes of these planes, a common breaking point was at the tail booms. I decided to beef them up a bit with some 1/16" balsa sheeting over the broken joints to use as also a joiner. These were glued in place with epoxy.
