[ALREADY REPORTED] Uncommanded trim/roll

[ST0RM]

Took up the Hornet from Tbilisi to a carrier off the coast. Set the A/P and immediately noticed a constant left bank, combined with a right rudder drift.

 

Checked the FCS page and the rudder was trimmed to <--4 on both. Tried manual adjustment, but it didnt remove the trim.

 

Additionally, no aileron trim would stop the A/P left bank.

 

What happened?

[DDSSTT]

Did you set HSEL or ATTH on A/P? (could cause unintentional banking)

 

Were you flying asymmetric load? (will effect BALT/RALT A/P if not trimmed)

 

Does your Stick have a proper deadzone set? (could effect BALT/RALT A/P from engaging)

 

Does your Rudder center properly? (will cause perceived trim error on FCS as all control surface input displays a value)

 

 

This would probably be best asked in the General F/A-18 Page, until this is determined to be a bug. Also, Mods will ask for track files and stuff here.

They can move it there, if they determine it.

But yes, I checked all my controls.

No asymmetric load.

Did select HSEL after a time to see of the jet would trim itself out, but it did not.

FCS showed no errors when running through the on ground test.

[ST0RM]

Ok, I flew it again and can replicate it. The screens have a tilt because VR screen shots the left eye and I wanted to ensure I got the DDI and HUD.

 

On the ground, FCS checks ok and controls set for takeoff

 

After takeoff

 

 

Rudders set to 4 Left by FCS

 

A/P Set, jet banks left HSEL set to 270

I'd say its your controller calibration or you're unaware of a duplication axis defined by a random controller?

[ST0RM]

It wasnt there prior to the latest OB update. Calibration is fine. On the ground it would turn if my rudders were out of cal. Ailerons would indicate it as well.

 

Can we get someone from ED to check this out?

Have you re-checked your calibration? Check that out, and make sure your axis mappings are correct. I have had to redo mine after updates, or they have randomly gotten messed up (can not replicate). Easy to check, just don't assume it's fine.

[DDSSTT]

This has to be a calibration, incorrect key bindings (rudder trim), or double bound axis for rudder.

 

Can you post a screen shot of the Controls Indicators, before startup, just spawn in cold and move your control surfaces around and let recenter. This will tell us if its an axis problem.

[Eldur]

Next time you see this, save a track and up it here, this sure will help the devs in case there really is an issue that's not on your controllers' side.

[Alphamale]

What stick? If something like a CH Fighterstick which has its own throttle, and TRIM wheels...you may have inadvertently bumped the roll trim wheel

[ST0RM]

Ok, so more testing tonight. I wasnt thinking that a CAP-9M and a TCTS pod were that different in weight, to warrant calling it asymmetric. But I was wrong. With that config (CAP-9M on left/TCTS right) the jet will add rudder trim and aileron roll the compensate. This is new, as in 2.5.2, a single CAP-9 would not induce much.

[Raz_Specter]

I have also experienced this on a random basis, flying and just letting go of the stick and the aircraft will just start to lean to the left, then because your leaning left it will start to nose dive

[Flamin_Squirrel]

I may have an idea what's wrong as I have the same issue some times. Hopefully others can replicate.

 

I think if you move either stick or rudder away from centre as you're loading into the aircraft, wherever you're holding it becomes the new centre point. Can anyone else try and see if they get the same result?

its happened to me when just taking off of the carrier then flying to some point. last time it happened I was not able to A2A re-fuel due to this issue

[macedk]

For testing, set is high deadzone if on a analog axis controller.

[Doum76]

On my side only time i ever have turning issues it'S whne i select A/P HSEL, even though i'm mostly facong straight my HSEL setup. But again been quite a while i haven'T used HSEL, i most of the time only use ATTH and BALT.

Funny. I'm flying right now and just noticed this. Thought it was me until I hopped on my phone and found this post. Even with HSEL, the thing keeps a slight left roll past the heading bug. The FCS page shows the ailerons are zeroed out, but still holds a slight left hand bank.

[Eldur]

If it's just slight, go and check your fuel page. There might be an imbalance in L and R wing tanks, had that once and don't actually know why, but it happens.

[drmorrish]

Same issue. Today. Multiple flights. But I’m a new pilot. Please help. Severe un commanded roll sometime left, sometime right. Depends on which direction I’m facing which is weird. Can trim it out but then I make a maneuver and it’s borked again. Dead zone 4 on tm warthog.

[JumpinK]

I just thought I had the same problem on my last flight...

 

...found the thread here and now I'm thinking even more that this problem occued during my last flight...

...will go for further testing now...

 

 

 

 

Edit: tested. couldn't replicate.

Calibration on TMWH Grip for me. Center was off by over 3000

[Darcaem]

Did anyone find any solution/cause to this?

 

I have just updated to 2.5.4.28090 open beta and it is happening to me. I'm attaching a pair of tracks from the Free Flight mission on Caucasus. I am experiencing this either when dark and cold, hot start, starting from the catapult and spawning on the air. Always with symetric loadout or empty.

 

 

EDIT: it is only happening with the Hornet to me

 

 

EDIT2: it seems that the aircrafts banks to the opposite direction of the latest "long enough" turn. If I do a 90 degree left turn, it banks right after leveling, and vice versa.

Also experiencing this, almost as if theres a runaway trim. Uncommanded roll both left and right at all flight regimes

Thanks. Didn't see it.
