Crash Absorber Fuselage

In making my epp plank wing I had inadvertently made a crushable fuselage - shock absorber when I extended the front of the fuselage by putting a smaller diameter rod inside a larger one. When I crashed nose-on the fuselage collapsed and just wrinkled up the epp foam and the motor just popped off, no real damage. Just hot-glued it all back together again.
Wish I had taken photo of fuselage all crunched up. Hopefully it wont happen again. I had just launched my plank but it was responding to a turn so slowly because the tail was loose and bending back and forth.
