An incredibly beautiful, detailed, and wonderful aircraft from Javier Rollon. Hard to fly, as per the real airplane, making it challenging and a real joy. Updated for X-Plane 11.11 and works very well indeed. You can install the GTN 750 and that also works very very well, though some people may say that's inauthentic. JRollon supplies an actual Australian air service livery, which is great for me as an Aussie. Support is readily forthcoming from the author on the forums. With the amazing aerodynamic real time modelling of X-Plane 11 and the astonishing attention to detail in this aircraft, it has my other aircraft sitting in the hangar neglected, and an aircraft of this level of excellence makes it hard for me to take FSX seriously at all any more. Well done to all. Highly recommended if you like this older style of plane. [I have no connection with JRollon or X-Aviation, just a very happy aviator!]
