HeavyArty:
As I had lunch I looked at the front page of the magazine I was about to read, and then it struck me!
The front page of Vertical Magazine (Dec 04/jan 05) it has the piccie I was looking for! This I found out by accident too!. The ribs are actually in an X pattern, 3 to the side on the 212, but then again the panel of the 212 (UH-1N) is wider than the UH-1D/H model,
Cheers anywho, and your picture sure was nice as well.
Have another as well on caaviation.com under the helicopter operations forum.
