Ok, first, get the crow idea completely out of your head.

Second, don't worry about the horns on the flap servos. You will never see them. They are on the bottom of the wing, and once airborne, they'll be too small to see.

I can relate to everything you're worried about - I go through the same thing with every plane I build. But something I have learned to deal with is...

Don't sweat the small stuff!!!

It seems like every time I jump through hoops to make something complicated out of something that should be easy, I wind up getting bit in the end.

So do it the simplest way possible - that way there's less to go wrong.
