RE: The F-22 raptor
Two wing rods. They look like they could be carbon fiber. Not your everyday trainer. I doubt you'd ever hurt one of them, but I have no doubt they'd hurt the rest of the airplane given the chance.
I look forward to flying one. The engine in the nose of a "jet" don't turn up my wick at all, but the planform looks interesting. That horizontal tail is mightly close to the wing.
I second the motion that it's not a very good design for a trainer. Repairing it looks like it'd be a nightmare.
