Thought that looked familiar. It's at the Ft Rucker Aviation Museum. They have a lot of interesting airframes there that would be nice rendered in FSX. Unfortunately the website doesn't have any photos, though they do have a text listing.

There used to be one rotting away on KILG. It was painted red, white and blue. I think it said Keystone Helicopter on it. I thought the American Helicopter Museum got it, but can't find it on their website.
That would be the Boeing 360 Demonstrator from the late eighties, the American Helicopter Museum does indeed have it in their collection. Look up N360BV
