April 8Apr 8 Well, it's probably due to completely different reasons among the two simulators I use, but the end effects are similar. In MSFS not all prop aircraft are afected which makes me tghink the problem I see with the default Beech Kingair 350i may be related to some wrong parameter in the "flight_model.cfg" or other CFG file, but since we do not have access to these files, I am unable to check it myself. The problem manifests as a completely unrealistic tendency of the aircraft to bank right, against all odds, at a wide range of power and AoA setings. Takeoff in the Kingair 350i and even at high power during teh initial climb you will have to fight it's tendency to bank right when left turning tendencies would be expected from an aircraft with powerful engines and two props rotating clockwise (CW). Take it to cruise level, adjust power for cruise as per the POH and you'll find that it continues to "want " to bank right 😕 You will have to either switch the AP / YD on or add aileron trim (to the left) in order to vbe able to keep wings level. Now this is an unexpected reaction from an aircraft with a pair of CW props, and I searched for fuel imbalance or cargo noto correctly set and affecting the CoG, but there's no evidence of that.

Have your tested your stick? Maybe there's drift... You have a good point here Jonathan, and I wish that was the case, but I've been debating this problem with the Xp12 devs, and it is well identified. In MSFS I started noticing it sometime ago, but I don't recall having noticed it in FS 2020. I have enabled the various visualization modes of the Forces and CFD in Dev mode, but those don't reveal any clues. You can easily test it yourself - just pick the default Kingair 350i and take it for a ride and it's easy to notice it banks right all of the time, most unexpectedly even at higher power settings and angles of attack... I don't know exactly what is the reason, and didn't have teh time to exaustively test all other default twin props in MSFS 2024, but I intend to, and will report back in this thread if I can. At least the Twin Otter doesn't looks like having that same problem...

Nope, mine flies straight and true, no such banking right thing. Maybe someone else can confirm, but I simply don't have this issue.

April 8Apr 8 Author Well, just tried it again, default Kingair 350 - it definitely wants to ban to the right, but it's the only default twin prop in MSFS 2024 that has such effect.

I oppened a thread at the Official forums: Why does the default Beech Kingair 350i bank right against prop torque tendencies? - Bug Reporting Hub / Aircraft & Systems - Microsoft Flight Simulator Forums I don’t fly the KA in MSFS, but I can confirm it’s same/same for the Hi Fi Airfoil Labs KA 350 in XP. It’s not quite universal in XP, tho, as the Default Lancair Evo does indeed turn/roll left at high power. Great, now I feel my OCD kicking in and I’m gonna have to go down the list to see which are affected - and that’s a LOT of aircraft!!! 🤣 edit: dcs yak-52 yaws/rolls left a2a Comanche yaws/rolls left (MSFS crashed…, dang it) Edited April 9Apr 9 by UrgentSiesta
April 9Apr 9 Author I believe there is some imbalance in the MSFS 350i but we're unable to read it's fm cfg files so... All other prop aircraft in MSFS, with CW props show the correct left turning tendencies, twins being less intense just like IRL.

April 9Apr 9 One thing I will add is that there are two King Airs so be sure to specify which one you are having an issue with. My old account was became inaccessable so I had to create a whole But I have been using flightsim for a quarter of a century, despite the counter which says I'm a new user...

Oops - I only see one 🙂 the 350i, with Garmins? I have FS 2024 standard edition. Maybe other editions have yet another Kingar? Ah, and yes, I am aware I can also bring the older version from FS 2020, and there are mods for it, and I did do so sometime ago, but I honestly do not recall how it behaved regarding this weird right bank tendency ...
