I'm a heli guy (yeah, yeah, I know you plank guys hate us

) so I really dont know about planes all that much, I had my little cousing bring me a TT trainer for repair (marked N40TT). All the damage believe it or not is from being in his garage [:@] Wing and Ailerons are fine, elevator, rudder and lower tail is trashed (see images).. Assuming the engine and electronics are working is it worth fixing? Where do I even get parts? Searched around Tower and a few other places and didnt see any parts for it... The plane has the following:
OS .40
Futaba 7ch Dual conv RX (FP-R127DF)
Futaba 3003 Servos All around
and a Futaba 500mAh Flight pack, will cycle out to test...
