That is all nice and well but 99% of us don’t have that kind of equipment and are pushing against a spring for most of the flight time. Therefore simple solution would be for Asobo to add trim to this helicopter (as they have done for all other default helicopters). If you don’t find it realistic, then don’t bind those controls and don’t use it. This is one of the only choppers to use in career mode and is close to unflyable with a normal joystick.
In real life there seem to be different systems, and even with the same systems, pilots use them differently. From what I have read, in the H145 some pilots prefer to press TR, move the cyclic, and then release TR. Others move the cyclic to where they want it and then press TR to allow the trim to catch up. The new implementation in MSFS2024 caters more to the second variant.
I agree with the first posted method for desktop joysticks. That way you are less likely to have unwanted inputs when releasing the trim.
The real force trim systems use magnetic brakes. There is an electromagnetic coil powered to create the magnetic force to hold the cyclic in its current position. Pushing the force trim reset button interrupts the power to the coil, disengaging the brake and allowing you to move the cyclic easier. When the button is released power is restored to the coil and the brake then holds the cyclic in the new position.
Beep trim with a top hat has actuators that physically move the cyclic in the direction you are clicking the top hat (MD500E has this)
The forces felt through the cyclic aren’t like the forces you would feel through the airflow pushing an aileron back to the yoke, for example.
The hinge system in the rotor absorbs a lot of the aerodynamic feedback…but at cruise, the rotor wants to slow down. So there is force against pushing it forward. There is also a roll tendency due to dissymmetry of lift (left roll for CCW, right for CW). It’s not strong, but you have to hold a little pressure against it.
Trim in the sim (which I think, incidentally, I’m going to title all of my videos now 
) is purely an accessibility feature and realism has no place in the discussion.
The developer team have wrote this in the h125 trim doesn’t function bug thread.
Okay, an update on this after further discussion with the development team:
It is normal that the trim release button on the cyclic in the H125 is not functional as there is no Automatic Flight Control System (AFCS) in the H125 modelled in MSFS 2024. The cyclic has this button modelled as the cyclic remains the same across the Airbus fleet.
The “Quick Trim” button has been implemented as a way to have trim release functionality but does not rely on the AFCS systems, which as noted above are not modelled in the H125 in MSFS 2024.
Keep an eye on the Release Notes for the patch scheduled for next week to see if the next update helps to resolve. Please feel free to report back in here if the Quick Trim button is working as intended after the next patch!
Thanks
The MSFS Team
Yes, but that would require a force-feedback joystick. Since most people don’t own those, the alternate method used by sims makes perfect sense.
“Quick Trim” seems to be either bugged or confusing to use, so we’ll see.
I’ve seen a few different claims of “insta-death” in cases where it’s been used in other helicopters in MSFS2024. Could be user error but I haven’t seen anyone explain how to use it properly.
Asobo’s response to this is nonsensical. The H125 clearly has a trim release button on the cyclic. So even without rotor trim, it should have SOMETHING. Yet,nothing works.
By contrast, the R66 implementation does NOT have the rotor trim hat on its cyclic (even though some R44s and R66s do have it), but it works just fine anyway via the control binding.
No logical consistency whatsoever, and thus a nonsensical answer to this bug from them. No one with a spring-loaded controller (or an XBOX controller) will ever want to fly this helicopter for more than a few minutes. It’s simply a requirement of simulated helicopters that trim be available. What a stupid place to lean into “realism” with all the other things that have been neglected in other aircraft.
The way I use the force trim button in the sim is to get the stick to a position where you’re flying straight and level, then press and hold the button you’ve mapped for trim release and return the stick to the center. Once you’ve centered the stick you release the button and your stick position when you pressed the button becomes the new center. Pressing the trim release button immediately zeroes all the trim so yes you need to be prepared for a wild change in attitude, but I have yet to crash doing it.
No it wouldn’t, I use it with a normal centering stick.
To be fair, cyclic controls often have additional buttons across the range that are not necessarily implemented or ‘spare’. See the H145 grip.
Sure, but that doesn’t work as well with non-FFB joysticks. The current method is a decent compromise, and should be in every helicopter in the game.
Actually, it can, and does work very well with non-FFB sticks in the system that DCS uses for trim release.
If a 20 story building with 39 giant rocket engines can be caught by a pair of metal chopsticks, I’d really think twice before so quickly declaring things to be impossible…
Is there really a need to make this complicated? With all the bugs needing to be addressed in this sim, wouldn’t it make sense to ask for the simplest action by Asobo to fix this problem?
Asobo has already implemented force trim release in many helicopters.
All we need to ask for is to have this existing feature enabled for the H-125.
I agree. I don’t understand why some users are making this complicated. The developer should add a normal trim function and everyone will be happy.
Helicopters are almost an afterthought, which is why the helicopter missions usually have approaches as if they are airplanes.
This makes the H125 a hanger queen.
For those who have a Microsoft FFB2, you can use simFFB wich offers force trim (instant trim) for helos. It’s free, open source and compatible with DCS.
It works great but it’s not perfect: sometimes it requires “reconnecting” the app via shortcut to reactivate the effect. It’s not a bad solution while we wait for better FFB support.
I can confirm it works well in FS2020 for the Westland Scout and Wasp too.
This lack of trim drive me crazy, and is pretty painful for the wrist on my warthog
indeed in DCS which is a sim, you can force trim helicopters,
For example, In the UH, you move the cyclic, set trim and let your joystick recenter immediatly to avoid “doubling” the “direction /forces”.
It takes some practice, but is a very nice solution to be able to play with normal joysticks.
In the KA-50, you press / move / relase to set a new position.
Another solution is to use a joystick that allows “dead stick” ( no springs ) but, it’s expensive / need a dedicated one to helicopters …
