The excellent possibilities offered progressively by the new Microsoft Flight Simulator (MSFS) has incited us to propose you very quickly a version for this simulator of our first realization, the Morane D-3801. As all the capabilities of the old simulators are not yet available, this version does not include all the elements presented previously, notably the airfields and the missions typical of the engagements of the time. We plan to offer them progressively in accordance with the possibilities offered by MSFS. This first update offers you a second livery of the civilian Morane HB-RCF, renovated version and the only one currently in flying condition, with a livery valid until 2020 and a current one from 2021. The pilot of this version also has a new face in homage to Daniel Koblet, renovator and pilot. But also amplified exterior sounds, taxi and landing sounds, window icing and other improvements. Manuals in French, German and English are included. You can enjoy the feeling of flying a WWII aircraft as the Swiss military pilots did in the 1940s-1950s, the improved Swiss version of the French Morane-Saulnier MS406, known in Switzerland as the Morane D-3801. At the time, the Swiss army concentrated its forces in the center of the Alps (called the Réduit), built many small airfields in the hard-to-reach valleys, and the unique Axalp firing range to train its pilots for mountain operations. The Morane D-3801 has been faithfully modeled with its aggressive look, period liveries and flight systems and features. All based on the only Morane still flying and the experience of one of its pilots. Weaponry not included. The 5 airfields modelled on historical documents from the previous version will gradually be made available for free download on our website www.swissmilsim.ch. The same will apply to the firing ranges. Missions may be offered in a supplement and will allow interested parties to take advantage of all the capabilities of this particular aircraft. The complete manual in French German and English are part of the installation file, it is adapted to this version, it describes in detail the very particular characteristics of this aircraft and the differences with the previous versions.
