The new Moza Force Feedback Yoke

How’s the experience with the latest version of FFB-Bridge? I’m interested in feedback from Moza users in particular.

@EconomyArc31614 I would be very interested in learning how to apply this tweak for my AY210 Yoke. What exactly would I have to modify?

Hi @CaptainJack8155,

This approach is useful when you’re handling trim through software that expects the simulator to manage it on its end (like Moza Cockpit, based on my testing). Works only on unencrypted aircraft you can actually edit.

The trick is to change this value in the flight_model.cfg file:

elevator_trim_limit=0.1

Note that for some planes elevator_trim_up_limit and elevator_trim_down_limit are set separately. In such case both should be changed.

Caveats:

  • This makes the trim actually ineffective in the sim, so you entirely rely on the FFB device for that matter (so it has to be changed back if using a non FFB device). But this is what we want.
  • You still see the trim moving in the cockpit (wheel, indicator, …), however there is no formal guarantee that it matches where the device “thinks” the trim et set. This is a minor problem I think.
  • AFAIK it makes the autopilot ineffective at least for the vertical dimension.

To my knowledge, this is the only viable solution with the Moza Cockpit / MSFS combination (as long as hardware trim is implemented as it is now, and MSFS doesn’t handle FFB devices specifically and Moza Cockpit does not implement something to compensate the non-FFB-aware behaviour of the sim).


That being said: FFB-bridge handles this to some extent, by applying a contrary force on the pitch. There is a slider that allows (in my understanding, but this is not precisely documented afaik) to adjust to which extent this compensation should be applied, depending on the plane. In this case there is no need to apply the aforementioned flight model trick (and it should not).

It is very promising and kinda works, but for now I failed to achieve the perfect behaviour with this technique. The possible drawback is to get a reversed trim effect when it over-compensates, hence the importance of the related slider. I believe the compensation should be driven by a more complex function (as opposed to a simple ratio), because the trim effect depends on several factors, namely the TAS (see this discussion about how this is calibrated in VP-Force).


Not directly related, but about AY210’s elevator axis I still struggle with the mechanical friction of that axis on the hardware side, which is very strong and uneven along the travel (while it is very smooth on the roll axis). Currently dealing with Moza support about this, but it makes the “pitch experience” quite poor for me. Still waiting for Moza’s answer but I’m wondering if other users also experience this ?

@EconomyArc31614, Thanks Ill give it a try but to bad it breaks AP.

Also I found another option that might work. I noticed that if you activate Hardware Trim in the MOZA software it continues to work with just the FFB-Bridge software running. In the MOZA software, hardware trim requires a fairly high static spring setting to be effective but with the FFB software it seems to work with a dynamic spring force making it more realistic. For example, if you adjust the trim on the ground, the axis won’t move until there is sufficient dynamic force to push it to the trimmed position If you unbind the in game trim, it functions similar to your solution without having to edit the flight model config. Not sure if the programmer intended it to work this way, but maybe he could add official support.

As to the friction in the pitch axis, that was the first thing I noticed when I got my unit. I wrote to MOZA as well but didn’t get a clear response. I don’t think their support is so great but another owner confirmed that they had the same issue. The fact that they added the friction compensation shows that they are aware of the design flaw. Personally , I don’t really notice the friction when I am simming but I do use the compensation setting at about 80%

Interesting, although it might be a little clumsy to rely on both… But I think there are solid chances that FFB Bridge will be able to solve the problem accurately by itself.

Thanks for the details. On my side I’m still discussing with the support, but I find this friction quite annoying especially because it is not the same everywhere along the travel : at some points it is clearly more noticeable and the movement almost “sticks”.

@EconomyArc31614 and everyone else interested in trim..

Try 1.5.1beta 2. Made major improvements to trim, but need testing and feedback.

1.5.1-beta.2

This beta includes substantial work on MOZA AY210 trim handling, with particular attention to the Cessna 172 G1000 in MSFS 2024.

The aim is to make trimming feel more natural: progressively relieving the pressure needed to hold the yoke while reducing unwanted aircraft pitch changes when your hand position stays steady.

What changed

  • Improved AY210 trim input compensation while keeping spring resistance and other force effects active.
  • Corrected spring-centre handling and the delivery of small trim adjustments.
  • Added aircraft-specific compensation for the MSFS 2024 C172 G1000 Passengers variant, including compensation for changes in control response with airspeed.
  • Expanded support diagnostics to help investigate trim behaviour.
  • Improved update-check errors: connection failures, certificate problems and server challenges now provide useful details instead of a generic internet error.

The aircraft-specific compensation currently targets that C172 variant. Other aircraft receive the shared AY210 changes but do not receive the C172 calibration. A quick X-Plane C172 check found no regression.

Please help test

  1. Load the C172 G1000 in MSFS 2024 and establish steady flight with autopilot off, using your usual FFB settings.
  2. While holding the yoke reasonably steady, apply a few small nose-up trim adjustments. Stop trimming for several seconds, then try small nose-down adjustments. Fly normally whenever corrections are needed.
  3. Notice whether the holding pressure changes progressively and whether the nose moves as soon as trim changes, before you move the yoke.
  4. Pause and immediately export a support bundle from Support → Diagnostics, so the recent trace is included.

Send the bundle with your aircraft, simulator version, hardware and trim-control method, plus a short description of what you felt and what the aircraft did.

Feedback on improvements, remaining problems and behaviour in other aircraft is welcome.

Once I know the trim is working better on the C172, I can generalize it across other planes. The idea is not to be stuck on this one plane - this is just for testing :slight_smile:

Hi @StarlessLion50 thank you very much!

I tested and made a complete report in the FFB Forum.

It seems to work great :slight_smile:

Hey @EconomyArc31614 and all you other trim experts, need some help. Beta 3 is out.

In this beta, I have expanded the trim compensation to 48 more planes (101 variants in total) for MSFS 2024. I have personally tested five of these (Cessna 172, Corvallis, DA40NG, Extra, P51D) and it seems to be OK.. but I’m not a pilot.

Could you test out the trim in some of the planes and give me some feedback, please? The full list of the planes is on the beta page.

PS: If you’re an XP user as well, there are pretty big improvements on that front too. Would appreciate feedback on that as well.

Trying it out now - my flights have been so nice lately I haven’t had to pay attention so much lol. Trim was working beautifully on my last flight in Kodiak Pro - FFB-Bridge really lets me dial in what I want to feel from the telemetry. Keep up the great work.

Latest update is out. Some fun new features..

try the new trim compensation in MSFS 2024.

Pro is out :slight_smile:

Happy to answer any questions.
