reversal aileron and elevator trim

hi ,

all axes are correctly assigned ( also graphically : in cockpit and on the plane ) but when I want to use trim elevator I am obliged to use aileron elevator and each other .

only rudder trim is ok .

Stick??

- joystick ffb2 microsoft ( x , y )

- trim rudder + trim aileron on saitek pro flight quadrant throttle

- trim elevator on saitek x45 ( throttle ) , 3 axes joystick x45 desactived

- saitek rudder pedal ( rz )

- simwheel for buttons ( axes desactived )

all that run well with DCS A10 , BS2 .

I wanna see your come back to that list Joey ;)

I wanna see your come back to that list Joey ;)

Is this good enough for you...:)

Reverse the trim n see what happens??

nothing

Do this:

DCS Options > Controls > select P-51D Real / Axis Commands > click inside the MSFFB2 row > click on the "FF Tune" Box > Check "Swap Axis"

It is working in the A-10/Ka-50 because you must have done it already some time ago , but you probably forgot to do the same for the P-51D.

thank ,

Now I haven' t reversal beetween aileron trim and elevator trim , it's ok .

But the action of each trim is not good :

- the plane go down when it must go up

- the plane go at right when it must go at left .

Also I note that only one trim-aileron on the wings-aircraft move instead of two-aileron ( usually : on up and the other down )

and the action on trim elevator only run if I take the joy in my hand .

please do now the obvious : invert the axis in the options .

It's not that I want to said :

The action of each trim ( when I take the joy ) is not good when I look at the aircraft ailerons .

For exemple if I see the trim-elevator go down on the aircraft , the plane must go down also but it's the other way actually .

Now the action on trim aileron run ( the plane move ) if I take the joy in my hand also as I had describe for trim elevator in the next message .

Without touch the ffb stick the plane should move when I use trim , usually it's run like that on other plane-sim !!

On your aircraft the two trim-aileron move or not ?

now also trim-rudder is inverted .

First things first:

Are the controls behaving like they should in flight?

Means:

Turning elevator trim forward = nose down and stick FFB forward (when having enough airflow)?

Turning aileron trim left = left wing down and FFB stick Left (when having enough airflow)?

Turning rudder-trim right = turning right in flight ?

Is this how it works now for you? Did you got it sorted in the controllers options ?

About what you see:

moving nose down = Trim Tabs up

Seems you have to read/think a little about the basic concept of trim-tabs...

Trim-tabs aren't chained to your stick.

Means they only move the controllable surface via drag. Here is a Image:

As you can see - the tabs (small parts at the end of the elevator in this schematic image) are have to deflect in the opposite direction - so they "drag" the elevator in the wanted position that is changing your flight path.

Once again:

Moving the trim-tab in the Airflow = produces drag that Moves the whole control surface opposite to the deflection of the trim-tab.

This also moves your stick.

About other sims/airplanes:

What air-planes what other simulations?

You have to distinguish how the control-surfaces are moved in a specific plane.

If a air-plane moves the control surfaces via hydraulic and/or motors ,

your trim moves the e.g. aileron directly and you use the trim-tabs only in emergencies. (hydraulic failure / loose of energy)

This method will result that you have a moving stick/horn according your trim even on ground when there is no airflow.

Have a look here:

But if you are flying a plane that moves the surfaces only via pulleys and wires - you will move the surfaces like described at the beginning at my post.

This method will result that you have a moving stick/horn according your trim only when there is enough airflow.

(BTW: DCS has the best FFB-Trim implementation I ever saw in a Flight-Sim)

Also I note that only one trim-aileron on the wings-aircraft move instead of two-aileron ( usually : on up and the other down )

and the action on trim elevator only run if I take the joy in my hand .

No, I can't acknowledge this - both trim-tabs at the wings moving as they should.

See attached track.

thank very much ,

I make a big mistake about the working of the trim , and it's run like as you say in your '' first things first ''

(conclusion : ffb must run for trim aileron and elevator ( not for ruddder trim , of course ) but not all the time !!!? and you can never let the stick as in real life )

As you show in your track yours two trim-tabs moving ( but your plane d' ont move ) , and not for me my right trim-tabs d' ont move since I Check Swap Axis , and I can' t re-establish it for the moment .

... I try again ( stopped on the runway ) and now I see that right trim-tab move only when I move the stick ( rolling ) .

at last I understand nothing
