Trim not functional (AY210 / MSFS / C172)

Hi,

After updating to 1.5.0 (from 1.4.1, I believe), I noticed that the trim handling was not working anymore.

At some point I felt like it was almost solved by FFB-Bridge, and that it was possible to achieve the correct behaviour. That is, trimming without moving the yoke should have no other effect than changing the perceived pressure on the pilot's hands (not easy to put in a few words but I'm sure you get it).

With the latest version (1.5.0), whatever I use in FFB-Bridge's trim settings, moving the trim without moving the yoke does actually change the plane attitude.

I believe that in the previous version, you did apply an artificial counter-effect on the yoke to cancel the trim effect and generate adverse pressure feedback. But it seems it does not happen anymore.

I think the trim subject is very important for FFB device users, as this is one of the main outcome you can expect from such devices. And unfortunately Moza Cockpit does not handle it very well.

Didn't try the 1.5.1 beta yet, but it's not mentioned in the changes.

I have made many changes and improvements to the trim in Beta2. Test it out and provide your feedback, please.

https://ffb-bridge.com/beta

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

  • Load the C172 G1000 in MSFS 2024 and establish steady flight with autopilot off, using your usual FFB settings.
  • 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.
  • Notice whether the holding pressure changes progressively and whether the nose moves as soon as trim changes, before you move the yoke.
  • 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.
