Here is the AS350Z, with the fenestron. It just so happens that our Eurocopter rep e-mailed this picture the other day!
Sikorsky also installed a fenestron to a modified S-67 Blackhawk. The machine was configured with S61 components, so the tail looked abnormally long and skinny, but was flown successfully.
