It flies nice. You still have to watch yourself on takeoff, but the handling makes more sense now. AH has been pumping out some pretty decent flight models of late.

I just removed my TSS sound moded version 1.2.0. I only did one flight and I think its an improvement, the slip ball seems to work better as apposed to totally broken but the turn indicator seems broken now not sure if it was broken before though.
I am now going to replace the audio with the STT pack I bought.
I got the TSS audio patched over which is great but this plane is still terrible. So many issues, itās so weird to take off. I found it more easier to take off on version 1.2.0 while full handling the plane. the rudder control was at least controllable before. I used to be able to nose forward to delay take off and control the rudder after the back wheel lifted now it seems weird and I canāt be bothered figuring it out. It should work as itās supposed to. Sadly the Asobo P51 Man Oā War has been broken since their last update ages ago and before that it flew better than AHās P51. Unflyable P-51D "Man O' War" - #36 by ExplorerJB

It also canāt be three-point landed. I donāt usually land it on three, but it should be able to do it. Some oddities remain.

Agree: it still needs work. But I am very happy to see that AH have revisited one of their most beautiful planes which I had believed abandoned fir good. So thanks for the effort. I am sure you will get it right!
I love the P51 Mustang, itās a pleasure to fly in DCS and IL-2 great battles. DCS is the best. Itās just AH P-51 flies so weird not sure how this flies with* assistance as Iām not interested in even trying that as I assume most people here also choose to fly it that way.
EDIT: I mean to write not sure how it flies with assistance and accidently wrote the opposite lol.
I canāt say on this specific one, but with other warbirds, I find them easier to fly without assists. Assists just mess things up that should be sorta natural. If you check other areas where people are asking about their planes doing odd things, often the first thing is āmake sure your assists are off.ā
Ok, so I donāt really know what I was doing before, but I happened to watch the video of the person who rewrote this flight model (https://www.youtube-nocookie.com/embed/FWHL2v9UASg and saw he did an effortless three-point landing. Then I went into the sim and had absolutely no issue with it. I had only tried once to do it before and it didnāt happen, so again, no idea what I was doing wrong.
I guess donāt draw conclusions based on one incident recalled from memory. Lesson learned.
In regards to takeoffs, the idea of keeping some back stick until enough airspeed is gained for rudder authority seems true on a lot of tailwheel aircraft, and certainly on this one. This technique works very well. Donāt nudge the tail up; let it up when itās good and ready.
Performancewise, I was going to make a couple comments about a suspicion that the new config was underpowered. Luckily I withheld my opinions until after the workweek of being tired and crabby. The numbers check out pretty good so far. 46", 2700 RPM, 5000ā ASL, 274 KIAS right on the money. Iāll check some other things out, but so far this is looking like a pretty stellar update.

I meant to say with assistance since I donāt use any of that.

For all who have trouble in handling the vers 1.3 Mustang I highly recommend to watch the vid mentioned by wartedsummer2 above. Thanks for this hint!
Iām having an issue with this and I think it is what was going on before with the three-point landing issue.
With fuselage tank empty and less than half capacity in the wing tanks, full flaps, gear down, low power (15-20" manifold pressure) below 130 mph - basically final approach settings - I lose all elevator authority and the aircraft starts diving. It does not do this when the wing tanks are nearer to full capacity, and gets worse (i.e. tail stalls at higher airspeed) the less fuel there is.
Can anybody confirm whether they have the same going on?
Yes - this is exactly the issue Iām experiencing - I tend to set 50% in wing tanks with nothing in the fuselage (typical airshow/aeroabtic) fuelling from memory and landings end more often than not with a noseover or a very nervy wheeler landing.
Used to have this issue in the Reno Mustangs and manually moving the CG back did the trick. Will give that a go next time Iām in the sim. Otherwise enjoying getting to know this update.
Yes, I remember the Reno P-51s doing that too. I havenāt flown any of them in a very long time.
Great video, I already worked it out though. My issue was that I like to takeoff on two wheels when flying the P-51 sadly I donāt think I can take off like that with this plane at least how I liked to scream on two wheel and get a bit extra speed before taking off. That was my problem I was just trying to do it like I do with my other P51ās maybe itās possible after learning this plane more as I ended up learning the last version.
I ended up going with just under 5 degree tail heavy, around 5 degrees right aileron trim and just over 5 degrees right rudder trim for take off.
I made a flight with the AH P-51 1.3.0 with TSS audio mod and recorded with flightcontrolReplay and captured the drone footage and replay using Nvidia shadowplay, itās nothing special. I did the drone stuff after I recorded in FCR when playing it back so I only recorded the airplane in FCR and did the camera when playing and recording the replay.
I got my three point landing in there as well 
On other sims I also like to land on two wheels that is what I like doing the most as itās not easy to do a smooth two wheel but I donāt think I could do it with this plane of ever or any time soon.
Eventually there will be a 1440p 60fps version to enjoy the P-51ās beauty once it done processing The 1080p is up 
EDIT: 1440p 60fps is up.
I used my Dualsense edge controller for drone work, I use DSX v3 to emulate the DS to a xbox 360 controller for better support and maping.
while i can now take off i do feel this flight model still isnāt right, take offs even in the linked video do not look like real mustang take offs and any video of a p51 take off is absolutely solid not a hint of any wandering to the left and the tail is up for a long time

The P-51D Mustang is a handful on takeoff. This if from a Flight Journal on the Mustang - āāStaying centered is no overly simple task; the P-51Dās Rolls-Royce Merlin engine and Hamilton Standard four-blade propeller develop a lot of torque. Right rudder in serious quantities is required to offset the pull to the left (five degrees of right rudder are, in fact, pre-set by the pilot prior to takeoff to ease rudder pedal forces), but once the airplaneās airspeed gets to the point where the rudder and vertical tail have acquired some authority, the pilot can reduce the right rudder input and start concentrating on other things.āā
I think the problem can be multifaceted, thatās not to say the flight model is accurate youād have to find someone with genuine P-51D experience for that. However when youāre watching a YouTube video of a pilot flying a P-51D now, they almost certainly have thousands of hours of experience, probably tail dragger experience before they would go on to fly the P-51D and therefore can make the difficult, look relatively easy with the smoothness of the take-off.
Also the rudder physics in FS2020 are, in my opinion, a little much. With most aircraft being really sensitive to rudder. Also of course as the speed increases the rudder effects change, partially on take-off and with a propeller driven aircraft as youre getting more direct airflow over it as it accelerates.
weirdly i can now take off perfectly straight with a nice tail up before take off heavens knows what im doing different seems so easy now
Biggest issue is that so much of stuff like torque, etc. is countered by āfeelā in a real plane, and you donāt get that feel in a flight sim.
An entire generation of flight sim fans were ruined by the IL-2 crowd who thought every plane needed to be actively trying to kill you at every moment, completely ignoring the fact that you get so many cues from lateral and g forces, sound, visual elements, etc in a real plane that you canāt get in a desk chair.

that is very true
Yeah the rudder is one of my gripes about MSFS. I think the systems trimming affects the slip ball incorrectly and my turn indicator in the AH P-51 seems totally broken but the other video the mod dev posted seems better, unless he has a separate fix for that. There was a fix earlier but I only applied the audio mod, maybe I need to try that but not sure if it will still work with the latest version. I just love flying the P-51 in DCS just going off the turn and slip indicator and using that to properly trim the aircraft as you can see what is happening accurately. I donāt know why others have gripes with IL-2 Great battles for a combat sim the flight models are really good and consistent as it should be when they create it all. Not sure how much 3rd party plane developers for MSFS can actually see in the code the slip ball and turn indicators seem to happen to many if not all MSFS planes from memory, to me this is a integral part of knowing what your plane is doing.
