I'm of the school that thinks beefing up too much - results in greater more difficult damage. I am not a CF user ... I prefer balsa and bamboo. They are much more forgiving ... can be glued back / scarfed easily.... and light.

My underbody has two balsa 1/4 sq beams set in ... my elevons have 1/16th balsa sheet epoxied to underside ... Those two mods create a stiff but easily repaired model.

The weakest part of the is model is first - the fuselage just where the cockpit line dips to run aft. The foam not only is thin, but has that air-hole underneath weakening it. Next is between the fins where the central section is moulded to take the beam. That needs to be fitted in my opinion with epoxy and plenty of keying in to tie those two sides together. Take the model and hold by one wing tip and see that area flex when nothing there !
