Hello Fellow Avgeeks; 

Im having a very annoying issue with the Duke v2. On takeoff its doing something that it has never done before. It pulls to the right EXTREMELY. Placing left rudder does nothing at all. After takeoff all is fine, rudder response nicely. During taxi all is good too. But during takeoff its impossible to keep it center.

Many thanks for your help.  

Look outside and see if the nose wheel is turned hard to the right and locked. Then we go from there.

Hello;

No, the nose gear seems to be centered. 

Thank you

I have this problem with almost every aircraft, not just the Duke B60 v2.  I pretty much have to recalibrate my saitek joystick before takeoff and that helps a little.  I do not know why it loses its calibration everytime I shutdown or start up FSX/P3D.  Still, that does not completely solve the problem.  I read somewhere that the solution is to make sure there is no winds in your default weather program and no winds (turbulence) in any addon weather program.  Still there is some difficulty keeping any and all aircraft centered on the runway at takeoff but it is a lot easier to go down the runway for the takeoff (or land).  I do not know who's fault this is.  The joystick, the weather programs (including the default), or the aircraft modelling.  It definitely is not as real as it gets and it's very frustrating.

 

Best regards,

Hello Jim;

Yes I know what you are talking about and I have accepted that some time ago. But the issue that I having now is even worse. Imagine that during takeoff somebody or someone is just pushing the right rudder and doesn't let go It doesn't respond to left rudder at all...... . 

Thank you. 

When it happens to me I turn on autopilot and set heading hold. Once stabilized, I turn it off and proceed as normal.

The problem does not occur with any of the RealAir planes on my PC but it does with several others.

Recently, I stopped using FSX calibration and went to FSUIPC. So far, that is working well.

Hello OldFlyBoy;

I dont use FSX calibration either, I like you,I use FSUIPC and calibrate from there. 

I have uninstalled and reinstalled the Duke, but that doesnt help. Just calibrated again, but still the same issue. 

grrrrrr......

Well, it clearly is not torque or it would pull to the left. I also doubt that the wind is ALWAYS from the left. This may sound absurd, but is it possible that the right wheel brake is dragging? I cannot think of anything else that might cause it.

I nearly lost my mind on this one awhile back. It seems there is a section called [CONTROL]  in FSX.cfg. There is a line in there that goes something like this (can't remember exactly)  controls=standard or something like that. When we calibrate controllers it creates another line controls=current. It seems that unless controls=standard is no-oped with // when FSX starts up it reverts to controls=standard and it appears the entire calibration is lost.

Hope that helps

Well, I decided to try the Duke again with all turbulence settings in FSX weather settings and turbulence turned off in ASN.  It goes straight down the center of the runway.  No problems whatsoever.  I will miss the wind buffeting all of my aircraft but at least I can go down the center of the runways with little or no effort. 

 

I have checked my calibration and it is now working so my comments above where I lost it occasionally are no longer valid.

I can say without a shadow of a doubt that whatever you are seeing is nothing whatever to do with the Duke. There is nothing in the flight model or aircraft cfg that could possibly trigger what you are seeing. I am absolutely certain that it is either your controls or some other unknown addon. The Duke was tested for hundreds if hours and not a single time did it ever deviate from where it should be.

 

There will of course be some drift because of torque and p factor but you can switch these off with your realism sliders.

Robert;

I have never said that the Duke is a bad aircraft or a faulty product.I know that it is a great aircraft and thats why Im using it All Im saying is that I started to hav issues with it and asking if anyone else has experienced the same and how did they fix it. 

 

Thanks,

Ok, 

Just tried Jims advise on turning off the weather. All working good lol. Hmmmmm, not sure why this happens, but okay. Very strange too, it happens when the power goes right above 50 percent the aircraft just turns to the right.

I guess I just have to accept that I cant fly VFR with weather. I have another weather engine called FSGRW, I will try using that one and see if its just ASN and the Duke, or if its all weather engines and the Duke that dont get along on my system. 

Robert;

I appreciate that. I assume you are talking of the piston Duke? (This might apply to the T Duke as well). Being a twin one likely cause of excessive drift on the ground is that either the power on each side is assymetrical or the props are set at different angles. This points to calibration. Have you tried switching off all controls and just for a while pressing f4 for full power then double checking that one or other lever is dead level with its twin lever, or using the mouse? It sounds to me like you have assymetrical power set somehow.

 

Obviously if there is a strong cross wind this can weathervane any aircraft into said wind. Have you tried it with zero surface wind, zero torque and p factor then checking the levers are equal?

Well, it clearly is not torque or it would pull to the left. I also doubt that the wind is ALWAYS from the left. This may sound absurd, but is it possible that the right wheel brake is dragging? I cannot think of anything else that might cause it.

 

I have these issue my self and maybe its related to ASN. But again the wind is from left and the planes nose still goes right. 

 

When the wind is comming from left the plane´s nose also has to go left btw ? (because of the push on your Tail/stabilizer)

Do you have wake turbulence enabled in ASN? That causes issues like you describe
