ASOBO P-51 IMPROVEMENT MOD

I've gone through and made new textures for the cuffed-blade prop for each of my P-51D repaints, which I'll post once Randall releases his next update for the aircraft.

For 'Moonbeam McSwine' and 'Little Rebel', which have cuffed blades fitted in reality, the details of the stencil work, decal placement and amount of yellow prop tip paint are matched to the real world examples. For my other P-51D repaints, all of the real-world examples have the later paddle-blade props fitted, so I did things a bit differently for those. For the Blakeslee Mustang and 'Val-Halla', I chose to depict one of the more common variations of the stencils on the blades. For 'Miss Kitty', I made the props match the details of those fitted to 'Sierra Sue II' (both Mustangs were restored by the same shop). And for 'Tall-in-the-Saddle', I made the stencils match the layout and mixed font-types as seen on the paddle blades fitted to the real aircraft.










Thanks John - all downloaded and looking great !
 
Hi Lou, here are the majority of those which have been made for the Asobo P-51D (not including the "Novawing24" payware repaints):

I'm not seeing any pilots appear in these repaints. Asobo base models are ok.

DVJ, that means that you have Russell's P-51D Improvement Mod installed, which is a good thing. With the improvement mod installed, the pilot model is added when you click on the Amber IFF light switch on the box circled in this image (just as you can also now change between the default late paddle blade propeller and the earlier WWII-standard cuffed propeller using the Red IFF switch found on the same box).

As JT said, the pilot is "toggled" by the amber IFF switch now after many reports from users with the "stock" Reno birds not having pilots. I never could figure out why some people got pilot models and others didn't but setting it to a switch seemed the most appropriate solution.

FS has always been about community input, and these are great.
I had kept the AH one, only because it had a ZK-TAF livery.

This is now becoming an excellent model, has the soundset been reworked, it seems better than what I remember?
I do still have some issues with the tailwheel losing the plot...

And what a superb paint job:

What's the verdict on the prop cuffs? It seems quite a radical attachment for seemingly marginal airflow improvement.

As far as I know, the sounds are still as originally published. Now, I have been testing the new Echo 19 soundpack over the last few days, and OH BOY are y'all in for a treat.

Due to the way MSFS treats flight models, I can't model the different characteristics of the cuffed prop versus the paddle blades IF I keep using the same methodology for the mod. That being said, I don't feel that the performance difference between the two would be so great to necessitate the extra work load of making different "variants" of the airplane that use different engine and flight models. I'd rather focus the energy on "next steps" of the mod such as remodeling the tailwheel and improvements to systems.

Here's a couple teasers of the Echo 19 sound pack.

Very reminiscent of Tiger's fly by sounds for Il2 Sturmovik about fifteen years ago. Many thanks to all. Be nice if the LOD of the aircraft could be extended somewhat.

The cuffed Hamilton Standard 6523A prop was developed when the Merlin engine was first added to the P-51 in order to maximize airflow through the induction intake under the engine. The cuffed blades were used on all P-51Bs, Cs, and the vast majority of P-51D production until the very last few D-model production blocks. They must have soon known/figured out, however, that the cuffs weren't really necessary as they used the non-cuffed Aeroproducts blades in 1944 and '45 as well, on the P-51K. The paddle-blade Hamilton Standard 6547A prop was developed for and introduced during the P-51D-30-NA, P-51D-25-NT and P-51D-30-NT production. The change coincided with those late production P-51Ds having internally strengthened wings, clearing them to carry one 1,000 lb. bomb on each wing, as opposed to all earlier Mustangs which were only cleared to carry one 500 lb. bomb on each wing. Where as the cuffed prop provides better top-end performance (greater maximum speed - why the racers prefer them), the paddle blade prop provides greater thrust on takeoff, thus more capable of lifting a heavily-laden Mustang into the air. In cruise, there is reportedly no distinguishable difference between the two prop types.

The paddle-blade Hamilton Standard prop, being introduced so late in P-51D production, didn't make it to the European Theatre, but there were some paddle-blade P-51Ds that entered service in the Pacific and CBI Theatres in the final days of WWII. These days, on restored examples, if they desire the typical "WWII look", owners will spend more to have the cuffed blades. Some Mustangs flying today have the 6523A blades fitted but with the cuffs removed, while a few others flying today actually use Albatross prop blades.

Any update when it will be released pls?

Thanks, very concise and detailed.
The cuff is an unusual solution and must have involved a great deal of trial and error.
Wartime, and racing, are strong performance drivers, aren't they.
 
Starting to tinker with getting the Mustang implemented into 2024. Flaps, ailerons, and trim are fully animated now. For reasons unknown to me, Asobo omitted the animation calls on the right wing components.

Seems like this is going to be quite the learning curve as the Mustang has a much higher level of "modularity" compared to the T-6 in 2024, so each change will be the same, yet totally different implementations.

Rebuilding prop materials will be necessary to use the new KTX2 texture format.

Found an interesting feature on one of the default Pitts. You spawn truly "cold and dark", clicking the canopy to "enter aircraft" slides the canopy back before your character transitions to the cockpit view, while leaving the canopy open for you to close once in the aircraft. Definitely going to look at adding that in on both the birds.

I wound up going out and buying a new Virpil setup because of this mod. lol Got my interest up (again) in flying fighters and landing on carriers. My old Hotas set-up really showed its inferiority when compared to my Virtual Fly equipment that I have been using. I guess once you go to good equipment, there's just no going back and flying a P51 with a yoke and throttle quadrant just ain't right.

LouP
 
Here are some work-in-progress shots of 'Jersey Jerk' (G-JERK) from this evening. I was very happy to get all of the tricky bits done, and just mostly lots of easy stuff remaining to do (though probably still another week or so until completion).




Get in there !! Thanks John
 
it would be good to change the tyres rubbed (diamond tread)
and add fuel tanks
It would, but it introduces some interesting technical difficulties that I don't know how to overcome, yet.

Fuel tanks are another point of contention. The fuel selector is only modeled for left main, right main, and fuselage tanks. So if I can actually model drop tanks, there would still be quite a lot of additional work necessary to make them function. I'd hate to just have the visual model.
