CFS3 Spitfire LF.IX, "YO-K" 401 Squadron RCAF
Stand alone update of MS stock Spitfire IXc representing 401 "Ram" Squadron, …
Spitfire F.IX in 340 Squadron Free French Air Force markings brings an early-war feel to Microsoft Combat Flight Simulator 3 with a reworked flight model, tuned Merlin power response, improved prop and boost behavior, refined virtual cockpit sightlines, and period-accurate loadouts for interception or attack; requires the Nationality Expansion Kit, Part 1.
This stand-alone variant refines the original Microsoft Combat Flight Simulator 3 stock Spitfire Mk. IXc into an early F.IX that served under 340 Squadron of the Free French Air Force. Developed by Rick (RCAF_Gunner) Rutherford, with a detailed repaint by Will Hunter, this package introduces a more realistic flight model, updated cockpit perspectives, and historically relevant loadouts. It also requires the Nationality Expansion Kit, Part 1 for proper functionality.
Within this enhanced edition, the renowned Merlin powerplant is tuned to reflect an authentic power distribution and throttle response, providing a more lifelike performance envelope. A meticulous reconfiguration of the propeller pitch and boost settings ensures that pilots will notice improved handling characteristics during high-speed maneuvers. Furthermore, the internal cockpit gauges (often referred to as instruments used to convey flight data) have been aligned more closely with historical references for accuracy in operational flight.
The visual standpoint from the pilot’s seat has also been expanded. The updated virtual cockpit (VC) views incorporate refined geometry around the canopy frame, delivering clearer sightlines. This enhancement ultimately refines your situational awareness when scanning the horizon or monitoring approach techniques.
The 340 Squadron (often abbreviated as FFAL 340) formed part of the Free French Air Force during the Second World War. Historically, they operated early Spitfire variants in numerous operations, showcasing remarkable cooperation among Allied forces. This particular repaint by Will Hunter captures those striking squadron markings and tail flashes, ensuring historical immersion. Pilots can thus experience historical authenticity when reenacting missions or exploring custom campaign scenarios.
Tailoring the aircraft for varied mission objectives, this update offers specialized payloads such as underwing munitions and additional fuel tank configurations. Users can select these loadouts to simulate altitude interception sorties or ground-attack operations, matching the diverse roles the Spitfire fulfilled in its service life. The underlying flight model also simulates changes in aircraft balance and drag, creating a more accurate handling shift in each loadout.
This package is entirely self-contained, yet it depends on the Nationality Expansion Kit, Part 1 for the appropriate country definitions. Rick (RCAF_Gunner) Rutherford has included thorough documentation in the included readme, outlining the installation steps to ensure smooth integration with your existing CFS3 setup.
