FSX/P3D NA Harvard IIb KF183 QinetiQ. Repaint of Warwick Carter's AT-6G as KF183, a Noordyun-built Harvard IIb which served the UK Military (RAF through various research establishments to QinetiQ) from 1944 to 2016. This is the ultimate color scheme worn by this aircraft, which is now civilian registered as G-CORS. Note that the model itself has an arrester hook which the real aircraft does not. By Andy Williams.
