Trimming Problems.

[VanjaB]

I never got into the habbit of trimming frequently in the Huey, but with the Mi-8 I found that its not only essential but it allows for buttery smooth rides and has made me a better pilot.

 

Recently I got back into the Huey (after spending a lot of hours in the Mi-8) and found that I have a significant problem when I tried to trim it.

 

Basically in the Mi-8 I would push the trim button, hold it down get my control inputs in the position I want them and then release the trim button. Rinse and repeat, works great.

 

Back in the Huey though, I ran into a HUGE problem with this method. For some reason after I press and hold the trim button there is a siginifcant delay of at least a second before my inputs are accepted and corrected, with catastrophic results. (Jerky jumpy movements resulting in a loss of control)

 

Am I doing something wrong or is this is a bug??

Compare your settings under Options/Special/<helo>/Central Position Trimmer Mode for both helos.

[VanjaB]

Checked the options, the setting is unchecked for both helos.

 

 

Would you like me to post a .trk?

That would not hurt, yes.

 

Both unchecked - that could probably explain why you experience a delay. The sim waits for a second (or so) until it takes your input into account. The idea is, that you use the time to re-center your (non-FFB) joystick after trim. With the option set to ON, there should be no delay, but the sim waits for you to re-center the stick (that could lead to situations where it seems that the sim completely ignores your inputs if you fail to properly re-center).

 

But anyhow ... if both helos use the same option settings ... they should at least behave the same way. Strange.

 

What joystick do you use? With force feedback or regular?

I use ingame FFB for Mi-8 and FFBSIM for Uh-1H for the same reason Vanja mentioned.

FFB Input delay fix:

Some notes on v.1.2.6

[VanjaB]

Saitek X52. So it should not be a ffb issue, since I dont have...ffb. :music_whistling:

 

Very strange. Ill try checking the option with the Huey, if that doesnt work Ill post a track.

[VanjaB]

Ok this is getting really weird. Now Im getting jerking motions with the option checked, although they happen after i release the button.

 

Here are two track files, first is option unchecked, second CPT checked.

CPTunchecked.trk

CPThecked.trk

[TimeKilla]

Got the same issue with my X52 and the Huey its like theres a small delay and its making it harder to trim was not there before.

[Flagrum]

What about PeterP's solution? Have you tried that?

[jay43]

PeterP's solution works just adjust the time to centre to your liking up if you want more time or lower it if you want it instant.

[VanjaB]

PeterP's solution did not work. I tried experimenting with lowering the delay to 0 and increasing it to 1 and even 2. I still get either a delay in registering axis movements after pressing trim (CPT unchecked) or a sudden jump in the axis movement after trim is released.

 

(Please see attached .trk files posted previously)

 

 

Could one of the mods/admins please move this thread to the appropriate bug subforum? It appears to be a genuine bug.

I will try today and post back was set to 0.5 in the file so it might work fingers crossed.

Not a bug Vanjb i watched your tracks and closely watched the animation of the stick you need to let it re-centre that jump is happening because you are keeping the stick pushed in the direction of force trim once you have applied it.

 

The only way i could replicate whats happening to you was by pushing forward on the stick then applying force trim and holding the stick in the position in which i applied it.

 

If i do the above but allow the stick to re-centre there is no jump what so ever.

 

What stick are you using and have you calibrated it in joy.cpl.

[VanjaB]

Jay, please re-read my original post. The trim method that Im using works flawlessly in the Mi8, wouldnt the same error register in the Mi8 if the method was incorrect?

[skouras]

just a thought

you dont have to press and hold the trim button adjust the controls and then release the trim button

what i do is to adjust

my controls and then press the trim

remember that in the UH-1 once you do that you have to recenter your stick with the new updates[this was not the case in 1.2.5]in 1.2.6 this is a bug

that is not the case with the MI-8 either

[lorenzoj]

Yes.... I was about to say that the "trim" does operate differently in both aircraft

[jay43]

Tried to help ya go and read the manual for both aircraft it works different one is made by Russians no disrespect and the other is made by Americans no disrespect so there fore the trim will not work the same way.

 

You are applying it wrong...

 

I have almost 200 hours in the Huey now so i know how it works.

 

I did read all your posts including the first and watched both tracks clearly you are applying it wrong.

Ok thanks for clarifying that, its obvious in retrospect that maybe just maybe the two systems cant be used in the same way. What is strange is that it took two pages of comments before someone mentioned that fact. I dont know why I thought that the trim systems wouldnt be modeled accurately but anyway. Thanks. :thumbup:

No worries VanjaB i haven't flowen the MI8 much i find it to be like flying an oil tanker with rotor blades she is a heavy old barge and not as nimble on her toes as the Huey.

 

Glad you got it sorted.

[159th_Falcon]

Didn't read the whole thread, but you guys are aware of the option under the special tab of each airframe called;

 

"use central position trimmer mode" ?

 

Cause if for one AC its on and the other its off you will see different system behaviour.

 

I have all AC set to the same setting here and they all trim the same in game.

VanjaB, the two systems are modeled differently because they are technically different in each aircraft and used differently in each. It's not just lazy programming......

 

Edit: PS 159th Falcon's tips is a good thing to check also for consistancy

I still get some delay when using PeterP's fix with FFB. I prefer to go with FFBSIM.

I never said it was, it just never occured to me that the systems are modeled differently. Anyway with the gracious help of other forum members, Ive got the Huey trim working correctly now. All it takes is a change in the method, I have to move cyclic first, press trim, release cyclic. Rinse and repeat, its different than how I do it in the Mi8 but it works.
