Question
Can we use some sort of carbon fiber shape, carbon fiber rod, carbon fiber tube, fiber reinforced plastic, fiberglass, Kevlar, or other composite material in the structure of our regular class aircraft?
Answer
The answer is always NO. The use of fiber reinforced plastic (FRP) of any kind is not allowed in the structure of a regular class aircraft. Teams are not allowed to use carbon fiber tube, carbon fiber rod, carbon fiber layups, fiberglass rods, fiberglass tubes, fiberglass layups, pre-cured composite sheet or shaped material of any kind, fiberglass, Kevlar or any other type of fiber reinforced plastic not listed here in the structure of the regular class aircraft

The sole exceptions are non-structural commercially available FRP hardware items listed in the rules: motor mount, prop, landing gear, and control linkage components.
