Given how difficult it was to come up with a shape I like, and given how many new features I tried with this craft, including the strut canopy and BD Armory TOW missiles/FLIR set, this craft took a lot less time to finish than I expected.  The Cobra's design was derived from the UH-1 Iroquois (Huey), and used the same engine, transmission, and tail section as the Huey. While the UH-1 made air cavalry practical, it was poorly armed and was vulnerable to ground fire from Vietcong or NVA force
