A little question about the Rudder Trimmer...

[Skulleader]

Hello ;)

 

I have a question about this option: Rudder Trimmer...

 

If I choose this option I can use my trim with my rudders it's more easy but it's not real, no ?

 

For the real flight I must not choose this option, right ?

If I not choose this option when I use my trim this device work just with my roll & pitch but not my rudder, exact ?

 

Please can you confirm me this constatation ?

 

A great thanks in advance for you help, Skull.

 

PS:

I join you one screenshot of this option:

I use it because I don't have pedals. There's no way I'm twisting a stick for an hour straight :)

Man you have to get yourself some good pedals...... the helicopter flying experience is like night and day with pedals. Put them at the top of your holiday wish list :joystick:

it's more easy but it's not real, no

 

I don`t know about the Mi-8 but in the UH-1 Rudder Trim is very real

[xxJohnxx]

Rudder Trim is also more realistic in the Mi-8.

[Weta43]

If you have no pedals, is it more or less realistic to not have to twist the stick all the time you're flying ?

 

If you have no pedals, it's a useful compensation for the unrealistic need to keep the stick twisted while in flight.

Hello guys,

 

I would like to thank you for your answers,

 

If I've well understand your explanations it's better to used this option, it's more realist ?

In the real life do you think that the pilot obtain this same result, always in the real life for the Huey or Mi-8 the pilot have the same sensation that us when we use the Rudder Trimmer ?

 

It's not easy to make a choice, I use the Saitek Pro Rudder + Warthog Hotas.

 

Once again a great thanks for yous help, best regards. Skull

Hi Skull,

 

what to say...use whatever fits your style of flying best..In reallity there is Rudder Trim, and the Pilots may use it..but you know..DCS is a Computer Game:joystick:

[skouras]

so in real life

the UH-1 and MI-8 does have a trim rudder or not:joystick:

i though that UH-1 didn't have any trim for rudder in RL

wow

thanks i didn't knew that...

can anyone confirm about the trim rudder for the MI-8 as well

According to the linked doc, the answer is yes, rudder is also included in the trim system IRL (page 55, sect. 2-33). However IRL there is no recentering after trim, only the forces are removed.

thanks but what do you mean only the forces move

[agentkgb]

thanks but what do you mean only the forces move

It means, that if you for exampe move the cyclic to the right, and you want to keep it there, more force will be needed to do that. After you trim, the cyclic will remain there, and will not return to the center (as for us, if you release your joy, it will go back to the center), and the force which you apply to the cyclic until you trim will be neutralized.

Just watch your virtual cyclic in the cockpit. You move it, you trim, and your stick on the desk will go back to the center, or you have to center it. But your virtual cyclic in the game will not go back to the center, it will remain in the new position. That's it.

This is what happens when you trim with force-trim rudders , they hold their position without the need to center them:

 

 

The same happens with the cyclic:

thanks guys exactly as i knew it always

 

so enabling the rudder trim option for both helicopters in special tab is the realistic option as it is in RL correct....

No, apparently not.

It's physically more realistic to keep your feet where they are when hitting the trimmer (same what a RL pilot is doing), instead to re-center them.

Read more about it here >>> Can we have this little Huey feature in our BS?

[Lizzard]

the Problem is..a usual Joystick does not know that you did some Trimming in DCS..so if you Trimm 10% forward the Game says..o.k. 10% Forward is my new neutral..but if you hold your Joystick in that Position it will keep sending a 10% forward Movement Signal..and DCS says ah o.k. i have to put 10% forward movement to my new neutral Position (overcompensation)..so you end up with 20% forward movement. This is why you have to release your Cyclic right after releasing the Trimmer button! In real life or with a FFB Joystick the Cyclic would just remain in that Position..so no need for centering the Controls..

[skouras]

ok so here a quick question again

assume that a real life UH-1H pilot

applies 10% of right rudder and press the trimm button

now he takes his feet away from the rudder

what is going to happen....

1. the rudder will remain at the 10% right position or

2. the rudder will re-center again

thanks buddy that was asking about..:thumbup:

Hello,

 

So for resume, we can say that for one person like me with the "Warthog" Hotas + Saitek Pro Rudder" I must not select the "Rudder Trimmer" because for the Mi-8 it's one cheat option, no ?

 

The second question concern the Huey, must I select the "Rudder Trimmer" ?

 

For the Huey I do not found one book or manual who talk of the Trimmer for the Rudder.

 

This question is a real nightmare for many reason, if you have other ideas it's very cool...

 

Thanks again, Skull.

[Skulleader]

Still me, I've found one video incredible and maybe one good tutorial...

For my part I've download this video because it's a good answer for my questions about this mysterious helicopter.

 

Link of this fabulous video:

 

If you watch this video at time code: 53:17 the pilot flying above the river and after turn on the right and operate one hover.

 

During this hover phase we can watch the feet and the rudder of the pilot, the rudder is turn to the right side at time code: 53:40 and the helicopter is perfectly hover.

 

So if we compare with our Mi-8 for have the same situation we must no select the RUDDER TRIMMER ?

 

 

At the time code 1:14:13 the pilot repeat the same situation with his rudder and of course the copter is hover.

 

Maybe we can learn one thing concerning the "RUDDER TRIMMER" and the goal of this thread, no ?

 

Well it's very late and I must sleeping, bye and see you later. Skull

Hi Skull,

 

in real Life, both the UH-1 and the Mi-8 have Rudder Trimmers. So to make it "real" you should enable them both (in order to get the pure function of rudder trimming). The Problem is...if you don`t have a FFB Joystick or Pedals..the pure physical mechanics differ from Real Life! So at your PC you have to do other things than in Real Life to achieve the same...a trimmed Rudder or cyclic. On your PC you have to center the Controls again, to not confuse DCS (you can fool that behaviour a bit with the "center after Trim" Option at the Special TAB), in Real Life the Trimmer System just "hold" the Controls na..better "center" the controls in the position you to told it to do.. In DCS you can even see how the System works...just look at your Cyclic and Rudders when you trimm. So if you want it as real at it can be, you would need FFB Controls (don`t know whether there are FFB Rudder Pedals out there). Finally we can come to a conclusion..use whatever fits your flying Style best:)

Hello dear Lizzard,

 

I can see that it's not so easy, we must make some choice but never we can obtain the same result than the real life.

I dream of one FFB rudder and HOTAS but it's nor for tomorrow..

 

I think that it's more easy with the airplanes because with our helicopter it's not easy because I really love the hardcore and to be the more realist as I can...

 

Thanks for your answer, bye. Skull
