Subject: Some silly questions...
This question has been bugging me a long time and I have been too embarrassed to ask. What is the difference between carbon fiber and fiberglass? I can I tell? Which one is heavier? Is tube better than solid rod for wing spar? I guess it must be lighter and more rigid? I suspect my solid rod spar is actually fiberglass although I don't know enough to tell.
