X-Plane 8 And 9 C-7 Caribou. The Caribou was purchased by the US Army and operated under the designation C-7. It is appreciated for its ruggedness and for its STOL capabilities. It differs from the Canadian version because of its nose radome and lack of a spinner. The RAAF opearated the type for over 45 years. Thanks to Dataroots for the sound files. By Jacques Brault.
