no bug P-51 cockpit shaking

[Rebel28]

The cockpit will start shaking for no reason while flying. It starts shaking so bad you almost can not read the gauges. This came with the new update. 

[saburo_cz]

It is probably not the P-51 bug.

A bug with plane shaking was reported for several planes and it seems to be connected with certain weather/wind setting.

[ascrr]

Same thing here, tried in multiple missions and instant actions and encountered it in all of them. It gets so bad that aiming and reading controls becomes quite hard. Removed mods and repaired the game but the bug persists. Newest open beta.

Spitfire does the same thing, though not so bad I can't read gauges.

I just thought it was some sort of wind buffet / engine vibration realism mod.

I think it's kinda cool...

[NineLine]

This should be cleared up now, are you still seeing this?

[Rebel28]

No seems to be back to normal now. Thanks for checking.

A year later, after installing 2.9 DCS.openbeta: p51 shaking madly when taking turns in cockpit view at normal speed

Now where can you turn this off? It's very annoying ..

What do you mean "when taking turns"? Maybe it's just pre-stall buffet? Difficult to say without a replay track. By the way, an airplane wing can stall at any speed ("normal" or not) but at a specific angle of attack.

I recall you used to fly with game flight mode enabled and buffeting is not present in that one. In flight sim mode it's there, however and can't be turned off. On the flip side, it's good to have it actually because without sensory feedback it's the only thing that warns us we're at the edge of wing stall.

Please supply a track of the exact problem and I will look into it. Thanks.

HI Art-J, NineLine ...... no gameflight mode is off .... airspeed is about 350 km/h.

Just tried another mission on the channel map with a p51, and there it behaves OK ....

The mission i experienced the shaking had Sunstag's WW2 V1 mod v1.3 in it, and this mod is no longer available so posting a track might be useless..

Here's a plain test track on the Normandy 2.0 map, also shaking, and the p51 is hard to control:  P51 test Normandy 2.0.trk

Thanks I will take a look.

Do you have curves set on your controls? Your movements are extreme and erratic it seems when I bring up the control display.

Hi NinLine. I use a warthog set, and since a month crosswind pedals v3.

Tuning yes, but quite minimal;

for Roll: Deadzone 3, saturation X and Y 100, curvature 11.

for Pitch the same but curvature 21.

Rudder (crosswind) Deadzone 0, Sat X and Y 100, Curvature 31.

 

PS a mission created on the Channel map with the p51 works fine, same settings. De-installed all mods (installed via JSGME), ran slow repair ... same behavior. Can it be some P51 settings to check?

Enable the data bar with LCtrl+Y and look at the Angle of Attack. If it's reaching high values (like 15 degrees and more) then it's normal that the plane starts shaking.

That's not it, only when you take a sharp dive it gets past 15, and then shakes more and too much.

A similar P51 job on the channel map shakes too when diving etc, but a lot less, and there i could not get AOA past 15. But i am still experimenting.

A spitfire setup behaves the same way more or less. I now begin to think it has to do with the map since 2.9 (updated DCS to the latest version).

[Art-J]

Different maps in DCS don't (and shouldn't) affect flight models apart from results of different density altitudes (via airbase elevations and ambient temps and pressures set in mission editor). These wouldn't cause different critical AoA, though.

In either case, If Nineline's vid from your track shows what you were asking about, then it indeed is buffeting caused by stall and, to answer your first question, no, it cannot be turned off in flight sim mode.

I have the same set up as you, but the control inputs I am seeing are much to drastic for the P-51. Its a high performance fighter but movements need to be smooth and steady. You also mention the Spitfire, I can only imagine you having more trouble there as the Spitfire controls are even more sensitive. You cannot slam the stick and expect the plane to respond smoothly.

@jackd
Usually no need for deadzones on your Warthog stick unless it's something wrong with it. Get an extension!

Thanks all, guess i must live with riding a DCS p51 ..

Soften those hands and it will be more like this:

You can lower saturation, it will transform stick movement to shorter elevator range. In those planes elevator movement range is much larger then it is used in flying.

Only cone from this will be shorten max deflection of elevator which in case of elevator damage may lead to lost control over plane.

Anyway if you complain about P-51 you should try Spitfire

The problem is we don't feel the accelerations in a simulation. Were you in the real one you'd probably stop immediately those inputs because of how uncomfortable it is. It takes time to interpret the visual and audio cues the simulation gives to you. Quite a lot of time I would say. That cockpit shaking is an important part of those cues in fact. It tells you the wings are starting to struggle to generate the lift you are demanding with the stick.

[NineLine]

practice practice practice. 

[jackd]

Well, been practicing a lot, but i guess i must fine tune the setup of my warthog set per individual plane. Do you use the T.A.R.G.E.T shell stuff?

Gave that up some years ago as being too confusing for me at my age ...

[Art-J]

Same here. Folks who want to have everything mapped on HOTAS and love using fancy input macros do use TARGET and good for them. For all the others, stock DCS customization options are plenty. Individual axis tuning was a must when I was using standard length Warthog years ago. I use extension nowadays but still add a bit of curvature here and there in more  pitch-sensitive planes like Spit, Thunderbolt, Mossie.
