c/f is brittle and will shatter, and thats a fact. We build things to bend, not break. Thats why the blue 20 and 40lb foam is so popular. It will give in a mid-air if properly armored. C/F adds to much cost and weight to any combat plane.

A blue foam wing with polypropylene leading edge, fiberglass spars and bi-directional tape are pretty dad gum tough and will take alot of abuse....
