MSFS: Spitfire Update 1.4.0 is here!

G'day Pilots!

Today we're excited to announce that the latest major update for the Spitfire is now available from our website! This update is the culmination of several months of working with the RAF's Battle of Britian Memorial Flight (BBMF) team. The BBMF have 6 Spitfires in their impressive collection of Warbirds, with thousands of hours of flight experience in the cockpit between them. We've been fortunate enough to work closely with the team; collecting feedback and observations from them as they put our Spitfire simulation through its paces.

Thanks to the expertise of the BBMF, we have been able to finetune our simulation to the highest degree possible - no aspect of the flight envelope has been left untouched! We are happy to say with full confidence that our Spitfire is flying just like the real thing, as confirmed by active Spitfire pilots using it for training! The flight model, engine & ground handling have all been refined to meet pilot feedback, with several of our custom aerodynamics systems being reworked & expanded to increase realism. To succinctly paraphrase BBMF pilot 'Disco' - "Power is on point, ground handling is also ... overall, well chuffed!"

It's been a blessing to work with the BBMF and a fantastic feeling to be able to finetune our sim and have it validated by the team.

Alongside Flight Model improvements, this update features a few major refinements, including the addition of authentic differential braking (via the wheel brake lever & rudder), new cockpit lighting and a major sound overhaul with significantly improved engine sounds and authentic flyby processing.

Take a look at the BBMF flying our Spitfire sim here:

You can also see a sample of the flyby improvements below! 

 Note that this was captured before final release and some refinements have been made since


 NB: As always, the update is available for our website now and will hopefully be available for Marketplace users in the next week or two.

    F I Spitfire IX purchased from F I for FS2020 on PC.
    I am also suffering “Aircraft over stressed” when canopy is open at any speed in flight, I also now have to fly with unrealistic settings.
    Please can you fix this problem?

  • Jerry

    Yes! Can you please fix the Canopy issue? Your Spitfire is super realistic! Why do we suddenly have to turn off crash damage? It’s not realistic, is it? It’s not mentioned in the product description that we have to turn off realistic settings! Otherwise I wouldn’t have bought your plane! So, please (!) fix it! I love your Spitfire! Regards, Jerry

  • Mark

    Patch 1.41 Xbox version. Upon takeoff (with canopy open) MSFS will immediately throw up WARNING “You overstressed the aircraft…”.

    This happens every time with canopy open. I presume no testing was done before patch release.

  • George Collicott

    I downloaded the latest update, after carefully deleting previous versions on my system. Whatever I’m now flying I don’t think it’s the latest version. I say this because I cannot fly under a bridge without it resulting in a crash. I thought the latest version fixed this bug. is that correct? How can I check to see what version I’m flying?

  • Renard

    would it be possible to include in a future update a repair option when the propeller is broken for example to avoid being forced to restart a flight? a kind of repair assistance, ground team …
