OK.
We all feel your fustration. This hobby CAN BE THAT WAY. But it also makes a good flying day better.
Trainers get beat up and trash bags are standard equipment. We all live with that. The old joke is pack a trashbag in the fuse so its at the crash site when you need it

All joking aside DO pick up every little bit of foam ( or balsa) as it is nice to have when rebuilding. Very few crashes are unrepairable.
A little bit of glue spread THINLY will put that back together NO SWEAT.
THE RADIO may be OK but I would do the range checks as said before. I also recomend loosing the ACT. Its like driving with hancuffs on in my opinion.
Years ago a buddy of mine mixed his Byron Christian Eagle (a 1/4 scale molded foam body) with a tainer in the air. He landed it but the foam under the skin was BAD. Around 100 pieces. He rebuilt it by restacking all the pieces back onto the firewall using lots of care to measure and keep straight. New skin and it flew for years.
