MSFS: Spitfire Mk IXc Update 1.2.1 Is Now Available!

G'day folks!

Today we have released update 1.2.1 for the Spitfire, which includes numerous systems improvements, greatly enhanced start-up audio and a fix for the dreaded cockpit light leaking!

Spitfire cockpit before and after the light leaking fix


  • Reverted fuel pump to OFF during cold start
  • Set default pilot to WWII
  • Improved fuel valve logic. The fuel valve can now be toggled with the Toggle Engine 1 Fuel Valve keybind.
  • GNS430 can now be powered on/off with the COM1 volume button
  • Improved the rudder trim wheel interaction speed
  • Fixed radiator flap not responding to manual override
  • Fixed clock animation
  • Halved the speed of icing
  • Improved the baro knob
  • Wobble pump logic improved
  • Added aileron trim control to tablets settings. Be sure to TURN OFF 'Auto Rudder' in the assistance settings as this is causing major right roll.
  • Base oil temperature slightly decreased
  • Optimized primer animation and interaction code
  • Canopy slide auto-shuts under a steeper angle now, making it easier to open on approach.
  • Transponder digit rolls corrected
  • Fixed checklists by removing incorrect idle/cutoff reference
  • Fixed CTD when saving custom camera views

Flight Model:

  • Slightly tweaked performance to compensate for SU9 changes (slightly lowered thrust at take-off)
  • Reduced wheel brake power


  • Engine starter whine sound re-added
  • New engine booster sound added
  • Added startup pops and backfires
  • Added prop sound when engine is turned off
  • Engine shutdown timing with sound improved
  • Improved groundroll and propwash transitions
  • General rebalancing


  • Greatly improved the cockpit shadows and eliminated almost all light leaking
  • Modified clock arms to more accurately reflect the real gauge

Thanks all,

Alex, Dan & Rai

    Flying irons planes top them all. Extremely well done and amazing to fly.

    I am very impressed by the Flying Irons Spitfire Mk.IX. It has improved with every update and is a thing of beauty. Great to fly in MSFS with a Buttkicker set up to add the haptic feedback. Sounds are fantastic and it looks gorgeous.

    Any updates on progress for the up and coming Hellcat or German fighters? Been checking Facebook avidly waiting for a sign.

    Just bought this version 1.2.1 for MSFS 2020 from MS Store – cockpit canopy does not close, and no choice of paint scheme.

  • Jas

    Fantastic work guys n gals. Dont know where you would even start to make these planes as amazing ad you have. Only one thing from me is that when the canopy is closed the engine is very quiet. I would like to hear the engine more with the canopy closed. Keep up the great work
