I'm not at that point, (just setting up the fuse jig) - but would really like to read about this as well. I expect weight would be a huge concern.
Along with this topic, can someone discuss their approach for hinging control surfaces? For a typical monokote-style build, you could use monokote in seal the hinge. How do you do so when covering with fiberglass?

Again, thanks for sharing your experience in this space!
