Chinese Stealth Tech- many think China borrowed fighter technology. I also think it would be foolish not to use proven ideas. Plus if your designs can be taken the only main advantages are strategy and training. This where the majors have the edge.
Although not a mantique, this freakin' cool and something I would love to make ~ With some determination, a few mistakes & a few burn holes in my shirt and skin, I made it, and if I can do it so can you.
