I've been going over my Delta, trying to find a way to hide the
antennaes in what is basically a rag and tube aircraft. (some of the
rags are soaked in epoxy, and some of the tubes ain't round...but,
anyway) I was beginning to think it wasn't possible when I happened
across this guys website:

Looks like it has possibilities. Has anyone ever tried this.

This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
