I saw this yoke on the Internet and though it'd be a great addition to JohnRambo's arsenal. Check it out:
Look at this fucking thing, it's awesome. You could put a pair of twin fifty-cal machine guns under the arms and a turbo boost on the back. Them caterpillars looks strong enough to drive up the side of a skyscraper. Next time John gets langers he won't have to worry about driving his chair down stairs - fit a pair of rocket engines under the seat and he can fly out the window!
No seatbelt, though.
Machine guns, rocket launchers, built-in RPG, this thing gives you maximum pwnage!!!!
