Oh, I wasn't referring to the overall workability of the scheme. I'll bet it could actually be done. My 'troll' comment was directed at the poster, not the post. "Hey guys, I'm mental patient and a deadbeat dad, and I want to build an airplane out of paper. How should I do it?" And when multiple people gave reasonable answers to that question: "No, that's not right, I'm going to do it this way." Maybe I'm wrong, in which case I owe the guy an apology, but that smacks of trying to stir up argument. Thus the 'troll' comment.
