Trim is strange

Hi,

I just flown a bit with the gazelle and noticed the trimmer does not fix the cyclic at the current position, but it seems to scale on both axes. Is this intended?

To me (as FFB user), it looks like FFB is not implemented, yet, and the trimming acts always as if in "central position trimmer mode". That means, I can't even use SimFFB here...

This could be the problem. Im on FFB too.

We plan on implementing FFB in the future. It's on our list of things to work on. The issue we ran into is that none of us actually have a FF joystick. So were working on getting one for testing.

A sort of work around I found for the time being: I un-mapped the trim button of the cyclic but (still) have it mapped within SimFFB. That way SimFFB takes care of the stick position and it does not interfere with the current central position trim logic - as I don't actually use the magnetic brake of the helo.

Caveat: the the trimming by using the hat on the stick does not move the RL joystick.

So the gazelle has a dual trim system. Here's the info from the manual:

The magnetic brake maintains the cyclic in a defined position. Pressing the magnetic brake  button at the pilot stick will define a new position to  hold.

The trim actuator will allow fine trimming, it can be set with the pilot cyclic china hat. Its main purpose is to allow the pilot to finely set the aircraft attitude,  bring small modifications to the speed etc ... It may be used complementary with the  magnetic brake system.

So Magnetic brake is sort of like the Huey/Mi-8 trim system. The trim part is more like an A-10C trim.

Basically I follow what the manual stated. Since I don't have a FFB I don't use the magnetic brake, just the trim. And like they mentioned FFB isn't implemented yet anyway.

Is it possible to have the magnetic break option to behave like Huey or Mi-8? Meaning when you press the button and release the stock it remains in it position? Currently when I do that fit example with the stick forward, the stock first jumps even more forward before going back to the position where I wanted it to be and causes the Gazelle to violently pitch down.

Just so you are aware, the latest version of SimFFB allows both classic trimmer and progressive trim at the same time.

I don't have an FFB and it wasn't my point.

I'm just asked the devs to have the magnetic brake button acting like the Huey and Mi8

Yes, I am aware of that.

.... the thing is ... what is that? how does it work? I enabled that option ocassionally ... but was never able to notice any difference ...? (compared to what btw?)

Then I don't understand your point here (probably due to my lack of non-ffb experience in helos).

Atm, even with a FFB stick, you have to re-center the stick after trimming so that there is no double-input into the controls. That is how it works for non-ffb in the other helos as well ... or isn't it?

My point is when I hit the button and recenter the virtual stick jumps in the opposite direction first. It seems that there is not enough interval between when you hit the button and when it lets you recenter it.

I'm after the same thing, I use Center Position Trimmer options in the special tabs of the of helos to avoid the "hump" or "Double Input" effect.

Definitely need that here with the Gazelle being so damn twitchy :(

Non-FFB user here btw.

having same issues, trim doesnt seem to work as it does in huey or mi8. it seems to me like it doesnt adjust the trim in anyway when pressing it.

I really miss the rudder trim while we're at it, I'm not a pedal guy so it's a wrist saver :)

didnt need any ruder input in forward flight tho. went pretty damn straight then

Once you get her over 100 you don't need any rudder at all.

gotta try that

The Gazelle is beautiful, but the trim does seem very broken. There has to be an implementation of central position mode with the magnetic trim for non-ffb users. Using the other graduated trim is fine tuning only, and doesn't have full authority.

Right now the mag trim is spiking when you click. Rather then giving you a delay to allow you to recenter.

Can we confirm if this is as intended or is it just something that will come right in time?

Same problem here.

Also the trim seems to not be able to over come high airspeed. You can full nose down trim and it still needs trimmer to be used.

But ya the trimmer not working is a pain.

Also the rudder authority is crazy.

The manual clearly states that the magnetic brake is for ffb joysticks and not recommended for non ffb and also recommends non ffb users use the trim button

This is all outlined in section 2.5 of the manual

And we clearly stated that the trim does not work with ffb joysticks.;)

Also... not really good enough.

No disrespect meant.

The KA-50, Mi-8 and UH1 all have similar electro-mechanical systems that zero forces. They all have implementations that allow it to be simulated for non-ffb users.

You need to be able to set the pitch, hit the trimmer, center the stick and carry on. Like in any other module.

The other method is for fine tuning only. Right now when you trim, it spikes the input and causes you to bounce around. As an aside, the KA50 used to do this too, before it was fixed. Also, using the other method in conjunction with mag trim, (as also stated in the manual Rocky) resets the mag trim...

I will completely understand if it's on the list of things to be fixed, or is something that got inadvertently broken, and will patiently wait for it to be fixed in due course. However if it is by design that a major control and stability system can only be used by a tiny fraction of flight sim hardware, that's a problem.
