P-47N‘s Flight Model is Crippled

if anything the p47N should have slightly better stall characteristics than the p47d

I like how vague the response is, sometime from now until the game is abandoned there will be an update that fixes this

The issue was said to be fixed… But after some flight tests I found the stall seems to be even worse… The plane will not only sudden roll but also get into a flat spin. I don’t know if gaijin really fixed the problem

AFAIK they won’t accept this, it is similar to the weight increase of N1K2-J a while back. One of the internal fuel tanks was only filled in the “overload” condition, but it was counted anyway.

J2M’s wing tanks should still have a little fuel in them in-game.

Did some light testing of my F4U-4 post-update:

I can now pull up to 16.9 degrees AoA before I stall out. 17 degrees causes one wing to drop violently (depending on rudder and torque).


At 16.9 degrees AoA we’re at 93% of critical AoA.

This is without maximum stick deflection. With maximum stick deflection & no rudder compensation on a left-hand turn (full yank: 18 deg aoa)

Result: at full yank without rudder in a left hand turn she immediately spins out pretty violently while WEPing.

This is a super rough test, but it looks like we got full elevator deflection opened up with full-real controls!

Already had some fun on the F4U-1D :>
With flap extended and more AoA available, the Corsair is much more manoeuvrable than before.

Weirdly, it seems fuel has a MASSIVE impact on stall characteristics.

Compare F4U-4B at min fuel vs 30 minutes.

At min fuel she stalls super gently. Wing drops, but if I take hand off controls she settles down.

(seems true for f4u-4 as well.)

20 min still seems to induce violent spins for f4u-4. 4B has gentle stall at 20 mins.

F4U-4 seems to be gentle on stalls around… 18 minutes. 19+ you risk violent spins, 18 and under it seems to be self-righting once you stop inputting elevator.

I haven’t try F4U-4 in depth. But I felt that F4U-4 is more easy to control than -1 near the stall, with combat flap extended, the -4 could pull full stick without stall.

The -1 will stall with combat flaps down, and it has poorer longitudinal stability such that the AoA periodic swing around 13-14 deg, in the cyclic period about 1 sec, and that the right wing will drop every 1 sec if you pull right at the critical point with flaps extended. A bit annoying during the dogfight, also the F4U-1’s flap lift coefficient is lacking compared with the -4 series.( CLmax 1.9 vs 2.1)

Any experience testing with 47s? I haven’t really flown them to be able to compare since it’s more subjective feeling than “check max AoA on F4U-4 and compare versus your report.”

I made a brief flight handling test on the P-47N and it seems to be great at stall. No more sudden thrown into flap spins.

It’s only a good thing if aircraft get full elevator usage now. I hope they’ve also fixed the P-40 as that FM was atrociously bad, the thing couldn’t even stall it’d just lazily roll over.

If the Corsair stalls the way it should now it’s a very very good thing. Before the Corsair had one of the most overly forgiving flight models in the game.

If aircraft stall properly now then well done Gaijin!

I would say even though the Corsair gets full elevator deflection and now is able to perform accelerated stall. Its stall characteristic is still inaccurate. Though enough to reflect some accuracy.

Currently the Corsair had around 17-18 deg critical AoA in clean condition, and it tends to roll right when stall in power-on condition. The stall is also quite gentle. IRL the Corsair has <=16 deg critical AoA in clean and performs a strong leftward torque roll when stall, especially in power-on landing configuration. Which was notorious and crippled its suitability as a carrier-based fighter.

I tested the Corsair last night and it’s still far too forgiving and almost needs to be made to stall. The Corsairs were fitted with stall strips to the wings to give the aircraft a more predictable stall in carrier landings however this did not help the Corsair with accelerated stalls, the Corsair was always known as a prickly aircraft to fly.

That massive prop and engine was known for creating a LOT of torque. In game it’s still on rails, the aircraft in SB is still massively overperforming.

I’ve noticed other flight models feel different too, the C.200 feels a ton more agile to me which is great but it’s still prickly to fly on the limit. Stall behaviour is still odd though, you can get it to drop a wing but at times it auto-recovers… still better than not stalling at all though.

What fuel levels were you working with? At least for the F4U-4 fuel makes an incredible difference for how vulnerable it is to accelerated stalls (under ~19 mins it’s very gentle. At 30 it feels it can enter a violent one but there’s a second or two of buffeting before you drop rather than the immediate response you get in 109Gs or Fw190s.)

Today I discovered that the same issue still persists in the chinese F-47N, and maybe in the P-47M(just a guess, didnt test it)

Not only the values of the flightmodel are the same as the older p47N model, but also the behavior is the same as the older p-47N. At this point, they are totally different planes

I also copypasted your bug report to apply it for the F-47: Community Bug Reporting System

I tried P-47N after FM fixes but, it is really questionable current FMs are correct because it doesn’t go stall/flat spinning when I pull so hard below 200km/h.

I‘ve tried the P-47N once after the update and I can feel strong buffet when pulling full stick. It is a little bit harder to stall it than other P-47, but I think the aircraft hits its critical AoA.

It’s a common issue that a lot of planes in WT Sim are harder to stall considering relative movement of the elevator. I think the slope of lift coefficient and the CltoCmCoeff do play a factor here, and also the elevator angle limits ( the one fixed for the Corsair in the update).

Plenty of War Thunder flight models are like this unfortunately.

Some aircraft stall and spin like they should.
Some aircraft stall yet magically recover even though you’re still pulling the stick.
Some aircraft just won’t stall at all.

I don’t know why they keep putting kid gloves on the FM’s. Have you flown the 190A’s since the last update? You practically have to force it to stall at times. Sometimes it’s as though the elevator has locked up at only 400km/h.

On the upside at least the Hurricane now stalls properly. Too bad the Macchi’s don’t…

what do you mean? It’s a while that I don’t fly props in sim

Have you flown the 190A’s since the last update? You practically have to force it to stall at times. Sometimes it’s as though the elevator has locked up at only 400km/h.

It seems that early FW190As are harder to stall when pulling full stick while FW190F and Dora stalls very fast if pulling a little too much. Looks they have different CoG, and it’s been a problem for a while.
