Wasn't able to test it yet, but the list is long, and looks promising !

===========

Sound Updates:
-   Fixed 2024 Sound Compatibility
-   Fixed infinitely looping sounds
-   Increase Engine Volume
-   Reduce valve & knob sounds
-   Reduce weird reverb sound

Flight Model Updates:

-   Introduced new wing airfoil lift coefficient profile
-   Corrected control surface area sizes
-   Rebalanced forces across all axes
-   Implemented a new suspension system

-   Introduced a new ground effect table
-   Adjusted control surface input scaling and effectiveness data
-   Fine-tuned engine torque and gyro precession setup

Vibration System: Running changes to the vibration system are intended to increase the quality of the simulation as well as fidelity. As the system advances, there is increasingly more user feedback going beyond the purely visual realm. The most recent changes include:

-   Introduced new vibration code for smoother animations, computed per frame for consistent performance regardless of FPS
-   Sources of vibration now include:
    -   Static thrust turbulence (high power, low speed, on the ground)
    -   Ground interaction (g-forces, bumps, and landings)
    -   RPM range smoothness (smooth around 2100-2400 RPM, rougher outside this range) 
        Added vibrations to:
    -   Rudder and elevator
    -   Throttle and wobble lever
    -   Control column and rudder pedals 
        Refined vibration algorithms for improved realism

Propeller and Ground Physics:

-   Smooth propeller animation now calculated per frame
-   Added multiplayer propeller support using Beacon Light 2
-   Improved taildragger physics core, based on Fw190 and customized for the Spitfire
-   Customized tailwheel animation to align with airflow during slips and drops forward during noseover
-   Enhanced groundloop algorithms for better differentiation between landing and takeoff conditions
-   Refined suspension behavior to match observed performance
-   Improved propwash steering and differential brake steering algorithms
-   Reduced ground effect and refined ground physics for smoother transitions

Drag and Performance Tuning:

-   Fine-tuned drag coefficients to meet top speeds accurately
-   Increased elevator trim authority
-   Balanced overall flight characteristics, maintaining known snap roll behavior
-   Retuned flap behavior to match official specifications (flap up cLmax: 1.36, landing cLmax: 1.80)
-   Adjusted propeller drag to align with expected approach parameters
-   Implemented new propeller and cD0 data
-   Fine-tuned high-speed behavior up to 0.89 Mach

Buffeting and Vibration Refinements:

-   Introduced new Lvar "Buffeting"
-   Enhanced buffeting logic, now accounting for speed and amplitude variations
-   Added 4Hz buffeting cockpit camera vibrations
-   Optimized buffeting and vibration algorithms

VR and Camera Improvements:

-   New organic camera setup considering head/neck rotation and eye position
-   Tweaked VR pilot camera position
-   Retuned vibrations for VR compatibility
-   Improved ground handling and roll sensitivity in VR

Miscellaneous Updates:

-   Consolidated and refactored exterior.xml for improved performance
-   Retuned control surface reactivity to match real-world aerobatic responses
-   Adjusted stall behavior for better aileron control during stalls
-   Refined drag for open canopy, open radiator, and slipper configurations
-   Improved slip coordinator using Incidence Beta SimVar

Man, planes like this are probably Superb in 2024!  Gosh I wish they could use 2024 as the base for a WWII sim as well and replace the PG with historical autogen instead...   

I downloaded it a few days ago but haven't had a chance to give it a try.

Very impressive/extensive update (and free!).

And just look at all those flight model improvements!!! ❣️

I'm looking forward to their P-38 Lightning (hopefully next if they keep their historical release pattern).

My home race track in NJ is New Jersey Motorsports Park in Millville NJ.  The two tracks are Thunderbolt and Lightning named after the P-47 and P-38.  

Quote

The Millville Army Air Field opened as a gunnery school for fighter pilots for the Republic P-47 “Thunderbolt” in 1941. During its four-year existence, about 1,500 pilots received advanced P-47 Thunderbolt fighter training here.

New Jersey Motorsports Park embraced this rich history by naming its marquee 2.25-mile racetrack “Thunderbolt Raceway.” The 1.9-mile road course – Lightning Raceway – is named after the P-38 Lightning, a WWII fighter aircraft.

New Jersey Motorsports Park also carried the historical WWII theme by naming its trackside condominiums “The Villas at Breighton.” Breighton was the name of an allied airfield in Great Britain, where many of the Millville trained P-47 pilots served during WWII.

Other ties to the WWII theme include the English Tudor design of the clubhouse, the Officers Club Q-Hangar design that contains Cumberland County’s largest banquet facility and the Timing Tower that resembles a WWII air traffic control tower.

While building the various structures at New Jersey Motorsports Park, many WWII artifacts were found and collected for display at the Millville Army Air Field Museum, located on the opposite side of the Millville Airport. The Bore Site range, located just outside Thunderbolt Raceway Paddock was used by Thunderbolt pilots during training as a range to calibrate their machine guns.

Today, a P-47 Thunderbolt- No Guts, No Glory aircraft is based out of Millville Airport. It is one of only nine in the world that still flies. Keep an eye on the sky when visiting NJMP – you may just see one pass by overhead.

Sorry for the OT but always think it's kind of cool when you pull into the track and pass the original WWII plane hangars which are just reinforced mounds of dirt built into the surrounding terrain.  Like a plane garage built into the ground.

Is this the 1.4.2 update - or have I just missed a newer/later one? Better go check my account/downloads! 😉

Does this work in 2024?

 So far, the OP and another haven't tested it yet....

It does indeed. I've just checked: 1.4.2 is the latest (which is what I have).

The only issue I have is that the wobble pump animation doesn't work (though it does function). Known bug.

Thanks for the headsup!

well all of those fixes for 2024 would be pretty pointless if the plane doesn't work in 2024...  If it doesn't work in 2024 then it's just completely broken LOL. 

Check YouTube for ITBs review.

off topic, but last weekend, Blackbird updated the PC-6 and the MV-310R

You mean you'd like to fly bomber escort over war torn Europe? 

Combat Sim 2024... 😍... At least the missions would be exciting and attract way more flyers. DCS & IL2 are too marginal these days.

Possibly but both have a vastly superior flight model…..
