Logitech G940: my personal review

Sporran asked me to translate my review of the Logitech G940, so here it is!
I hope you’ll like it and find it useful, because I already know it will take me a loooong time to write it in English…:rolleyes:

Premise: if you have always used spring-centering, non-FF sticks, I don’t see any good reason, except the dual-throttle, for which you should prefer the G940 instead of, for instance, the X-52 Pro (which I had for 6 months before switching to the Logitech).
If, instead, you are fanatics of ForceFeedback joysticks like me;), but your MS Sidewinder FF2 still works fine, keep it for bit longer and wait some months before buying the G940!

I’m not saying that I don’t like the new Logitech HOTAS (in the end I’m quite satisfied with it;)), but it still suffers from some “theething troubles”, both in the hardware and software, that will be probably - and hopefully - solved in the near future.
You can find some examples in Logitech’s Support Forum, for instance here or here. As you can see, users look happy about the product itself but everybody’s asking for improvements of the drivers and the profiler software, which anyway benefit of Logitech’s attentive support and have already been updated twice in the last month only.:slight_smile:

Below there’s a list of what I like and what I don’t about the G940.
1) The joystick has a “micro-jerky” movement. I don’t know how to properly describe it in English (some one said it’s like “moving the stick over a washboard”), but when you move the stick around you can clearly feel (and hear) that it’s movement is not continuous: instead, there are like small intervalls which correspond to the different positions. It’s not a big issue and you get quickly used to it, but nevertheless it’s a strange step backward respect to the Sidewinder FF", which provide a mush smoother feeling. Moreover, according to Logitech the G940 uses helical gears instead of straight ones, which should result in a smoother and quiter functioning, so I really can’t understand this behaviour.
2) Most of the times, when you take your hand away from the stick, it starts to emit a “crackling sound”, similar to that of a failing hard-disk. Again, it’s not a big deal since you just have to touch the stick, slightly pushing it on one side, to stop it, but it’s really annoying!:mad
Logitech explained it saying that it “comes from the small micro-responses of the motors centering the stick when it isn’t being held”. In practise, unlike the SW FF2, which deactivates the motors and becomes limp when you’re not holding it, the G940 keeps the stick centered even if you’re not using it: but since in that condition there’s no load applied on it, the motors shift back and forth rapidly and this generates the “crackling noise”. When you move the stick slightly (just a shred) off-center, I presume the very small load generated by the weight and the inclination of the stick itself becomes already enough to force the motors to push in one direction only, stopping the noise.
However, while self-centering can be nice because it mimic the behaviour of a spring-centered joystick (neutral stick whenever there’s no load applied to it), I hope Logitech will introduce an option in the profiler to deactivate this feature (I asked for that in the forum, together with other users), which otherwise can be overridden by covering the deadman switch with some tape.
3) My left throttle makes a bad noise when pushed forward from idle position, a “squawk” like if there is too much friction between the moving part of the throttle and its base. The funny thing is that I managed to reduce it to the minimum increasing the strength of the spring acting on the throttles, which doesn’t make much sense, but anyway this is a really stupid problem and I haven’t found anyone else reporting about it in the support forum.
4) The rudder pedals are very precise and sensitive, but although their movement feels great and its resistance depends on how the spring is set, the static friction (the one you experience before you actually start moving it) is a bit too high: this means that, when the pedals begin to move, the force you’re applying is too big and you’ll have a very hard time trying to get out of it just the small movement you wanted. (at least that’s my feeling, and I don’t remember to have had it with the Saitek Rudder Pedals, but it could be that I haven’t found the best settings yet…).
5) The 5 wheels (3 especially thought for trimming, on the base of the stick, plus 3 more on the right throttle) lack a “small stop/resistance” indicating the center, which means that you have to look the mark painted on the wheels to know whether they’re centered or not - not the easiest thing to do, if you fly in a completely dark room like I do to make best use of TrackIR…
6) The 2 buttons at the top of the stick are a bit too far away, thus a slight change in the position of the hand is required to push them (and my hands are not that small…;)).
7) The upper hat-switch works as a mini-stick (it has analogic axes) and everybody says it’s great for radar operation in F4:AF or LOMAC, but at this stage it can’t be used as a mini-mouse (like the one in the X-52) so it’s almost useless for IL-2 and in fact it’s the only part of the G940 I’m absolutely not using…:frowning:
8) The color of the 8 buttons on the throttles’ base can be changed (green, red, amber, or off), but not only at the moment there are no scripts to make them interact with the sims, which is normal due to the recent release of the product; the bad point is that the is just a “demo” program to set the colors, which does its work but doesn’t allow to save the settings! The results is that all the buttons go back to default green every time that the pc is rebooted…:mad: Again, I asked in the forum for the implementation of an appropriate control panel in the profiler, similar to the one of the X-52: it seems to me such an easy thing to do that I can’t understand why it’s not already there, but incredibly Logitech doesn’t seem to be keen to add this option, since they say the buttons are thought to be controlled interactively and thus they’re supporting the various software houses to implement the scripts in their sims (as if Oleg would re-work on IL-2 to add this feature…:mad:)
9) It’s not easy to reach the buttons to couple/uncouple the throttles, since they are under the grips.
10) There are 4 cables departing from the joystick’s base (1 for the throttles, 1 for the pedals, 1 for the power supply plus the USB one), and if you don’t wrap them together your desk becomes like a spider web…

1) It’s the only HOTAS system provided with ForceFeedback!:cool: After passing from the Sidewinder FF2 to the X-52 Pro I can easily say that FF is mandatory for IL-2, but also the convenience of having a separate throttle (2, in this case;)) and a plethora of buttons and hat-switches is a great advantage: the G940 has them both, and this will remain its exclusive feature in the near future. That’s the main reason why I spent 300€ more after buying the X-52 Pro (and its pedals) just 6 moths ago…
2) There are TWO throttles!:cool:
3) The product is very sturdy and the materials are nice for both the sight and the touch, except the 2 cross-shaped hat-switch which are solid but look a bit too “made of plastic”. Anyway, the overall “hardware quality” is very high.:slight_smile:
4) The stick is very very precise: even with the “jerky” feeling, it allows to aim and shoot better than what was possible with the SW FF2. In fact, the is still a quite big “play” around the central position, where the motors don’t oppose almost any resistance as it was in Sidewinder, but the G940 responds perfectly to any movement made in that area, without any dead-zone, while I can’t say the same for my old Microsoft joystick. Moreover, the shake/vibration effects reproduced when shooting don’t alter the aim, even if you keep then powerful.
5) The throttles, apart from the “bad noise” and the impratical couple/uncouple buttons, are simply perfect!:slight_smile: Comfortable (more than the X-52’s one), sturdy, precise, DOUBLE, with 4 buttons and 2 hat-switches placed in ergonomic positions, and the 8 big colored buttons on its base which are much more practical than the 3 2-position switches on the base of X-52’s stick, since you don’t have to cross your arms to use them, if you don’t want to get your right hand off the stick, as usually happens. Then, the “blocks” that separate “idle” and “full” positions from the main travel are less pronounced than in the X-52, where there is almost a “step” that doesn’t allow to set the engine at an intermediate regime inside it, which is better for controlling piston-engined airplanes not provided with afterburners or thrust-reverser.:wink:
6) It’s much easier to trim the aircraft using the wheels of the G940 than those of the X-52 Pro, which by the way are just 2 and thus force to control one trim axis via keyboard. Moreover, if the sim allows it (as Black Shark does, for example), since the stick is a FF one without any fixed centering spring, it is possible to trim the plane to have “zero force” on the stick for the the desired attitude, like in real airplanes, instead of trimming looking at the monitor and trying to make our plane go the way we want. It’s a pity that IL-2 doesn’t allow this, because it’s a really cool feature!:cool:
7) Between the stick and the throttles, it’s really plenty of buttons (20, compared to the 16 of the X-52 Pro) and hat-switches (4) and auxiliary axes/wheels (6, counting the additional throttle, whereas the X-52 has just 3): you really can’t ask for more, and in fact consider that I still don’t know what to use one hat-switch and one wheel for… they are simply too many!:smiley:
8) It is possible to set up 4 different parameters affecting the FF: strength of the centering spring, strength of the effects, “damping” and “artificial centering spring”. The first 2 are the normal actions usually found in FF joysticks, while “damping” is used to smooth the other effect (for example, like if the stick were immerged in oil, instead of air - a feature that I found completely useless, but which is anyway there and might be good for some specific use) and the “artificial centering spring” overrides the dynamic FF centering and makes the G940 behave like a normal spring-centered stick, with a much smaller “play” around the central position. This given, the “central play” typical of normal operations (as described at point 3) doesn’t seem to be a hardware feature, and it is also possible that Logitech will introduce the option to control it via software.:slight_smile:
9) The profiler is very user-friendly and it’s much easier to use than Saitek’s one.
10) It is possible to calibrate EACH single axis.

Ok, that’s it!:wink: (after I don’t know how many hours…)
Waiting for comments and eventual questions.:slight_smile:

Thank you so much BANZAI, i had read reviews on other sites but a hands on review by an EAF’er carries a lot more weight for me.


Was looking at this when my X45 craps out, where is the cheapest and how much does it cost?

259 quid on Amazon I might be slightly mad but I’m not certifiable. Not yet anyway :slight_smile:

Ooops forgot the main one, I’m left handed most joysticks are right handed, could I use this one?

Splash :banana:

I found some info that helped me a lot to adjust the force settings:

These force settings settings work fine for IL-2 :slight_smile:
I run the latest drivers 5.08, but 5.09 will be out in a few weeks.

A stupid thing is that the force functions disapears when Alt-tabing in IL-2… Returns only after restarting IL-2

The first slider, Overall Force or what it is called, is the only one that controls stuff like vibrations, including gun shake, buffeting, getting hit, bomb release and so on. Important to note that is also acts as the ultimate multiplier of the other two sliders as well, spring and damping. It’s the head honcho slider. If set very low, it doesn’t matter what you set spring and damping to, the stick will be lifeless. And if set over 100% just the same, it will also make spring and damper stronger. Something to keep in mind when tweaking.

The second one, spring, is pulling/centering forces, that get stronger the further you move the stick from where it wants to be. In IL-2, this affects how strongly it will resist movement as the plane travels faster (more air resistance on control surfaces).

The third one, damper, is in force feedback a simple effect that is just ‘resistance to movement’, with no necessary center. Imagine that the cables/wires in the control column leading to the wing surfaces has friction no matter what speed you are traveling, then this ‘damper’ effect would simulate the resistance that this friction is giving. (When checking out that test program and reading about effects, I saw that the stick also supports ‘friction’ and several other neat sounding effects that I got to try out. Friction was a variation of damper but slightly different. Doesn’t seem to be used in IL-2 and the force feedback editor (which is from 1999) doesn’t even support that effect. Either way, I have not ever found proof that ‘damper’ as an effect does anything in IL-2. There’s no resistance what so ever when flying up into the air and going below 120km/h no matter what damper is set to.

Lastly there’s the self-centering force. It adds the equivalent of a mechanical spring that only wants it to center all the time, without exception, and it adds to the effects that are already taking place. It does not work well in any form with IL-2 and I don’t recommend trying to.

From having tinkered around, I find that the following setup is ideal for me, at least.

Overall Force: 112%. This adds much more sting to the general effects like MG, Cannon, bomb, buffeting/turbulence and such things, without being overbearing or very loud. For some reason there’s a HUGE difference between the default 100% (very, very anemic) and even 112%.

Spring: 90%. I tried setting to 150% and thereabouts to get a more ‘real’ feeling, but two bad things happen instead - Firstly, it’s even harder to feel how fast one is going based on airspeed, because the airspeed effect seems to go from no resistance around 120-140km/h, to full force by about 300km/h+. With increased spring tension, it feels like this threshold is even narrower, with it being ‘very tense’ by something like 200-260, making the whole range smaller. Even going relatively slow at 250 gives the impression of being much faster. Secondly, the point of travel when stick goes from ‘slop’ to force feedback effects is even more pronounced when the forces are stronger, and it feels even more unnatural - to ‘break’ into this force one has to pull somewhat hard, and it makes it suddenly ‘jump’ too far as one puts enough force to make it start moving past this point (often all the way to the edge of travel). With spring at 100% it’s more progressive and the range when it goes from loose to firm (that sounds naughty) seems larger and more useful, and the ‘end’ result, max force, is about the same anyway. In my case, I set it to about 90%, because it’s multiplied by the 112% of the overall force slider above to be about 100%.

Damper: 90% I leave it at 90% like spring, not being able to tell any difference. Can’t hurt.

And no self-centering, of course.

I also bought one of these about 2 weeks ago and am still getting used to it. I think Hans has covered the system very well. Things I’d emphasise:


  • FFB OK but not as good as the MS2; the jerky movement seems to be a point around 20 degrees deflection, especially in pitch, when the motors kick in quite suddenly and can lead to you ‘snatching’ the stick backwards more than you meant. This is annoying in a low speed turn near the stall but you can get used to it and it is not catastrophic.
  • FFB sometimes stops, usually if you have to alt-tab. This makes the stick completely limp and flying quite tricky
  • No centring indent for the trim can lead to slight difficulties. Also, the rudder trim can be hard to find without looking
  • mini-stick useless in IL-2 so far though the throttle one I use for views
  • Top buttons usage runs danger of accidentally activating the lower buttons so you have to think carefully what to assign that is not critical (ie don’t assign ‘map’ above ‘bombs’ :()


  • The twin set-up is great for setting RPM and boost, allowing better optimal performance. This should become more important for SoW
  • Lots of buttons, all easily accessible, on the throttle including hats and wheels
  • 8 buttons on throttle base though as Hans noted they do not yet change colour to reflect function (a bizarre oversight from Logitech)


  • Widly spaced and feature braking as well as rudder axis
  • Variable tension though as Hans mentioned this does not seem to be terribly progressive and it is difficult to input small movements (these are my first pedals, though, so it may also be me)
  • I find the breaking quite difficult but again this is probably me

Overall; for £250 it’s quite a good deal. The throttle is the best part of the system and the pedals very serviceable though could use some work. If the stick had the MS2 characteristics it would be brilliant but as Hans said there are lots of variable to play with so I’m happy to play with settings over time :slight_smile:

IL-2 has only one brake function (same for all wheels). So I have the same brake on both pedals. Meaning that I did not assign this via the IL-2 HOTAS panel (that handles only one command for one axis), but rather via the Logitech programming menu for both pedals (via an assigned key “b” on the keyboard).

I am happy with it, but after alt-tabbing forces will dissapear, as we said. Then it feels as sloppy as my old Saitek X-52 Pro.
I went back to the X-52 to compare, but I prefer the G 940 anytime. Especially with the force settings I suggested in my post above, then it feels very realistic in IL-2.

Just keeping my fingers crossed that the alt-tab bug will be fixed with next drivers.

Anyone out there has seen the Saitek X-65 yet. They are going into another world price-wise. X-52 pro is as much as I will spend on a stick. But the features and build quality of the X-65?

Simhq review Saitek X65:

Simhq review G 940:

This weekend I’ll try changing the input settings for all axes.

As regards braking, I have set the little finger button to brakes so now you hold that and apply rudder as was standard in RAF and Russian aircraft at this time. Works pretty well :slight_smile:

I seem to have lost FFB and cannot find how to switch it on and off in the profiler. Can anyone point out where this is? :confused:

Check the slider of the FFB strenght in the control panel of the stick.
And check also that the power supply cable is properly plugged to the stick itself: I’ve found it several times to be not fully plugged, with the result that, although it seems connected, in reality the engines in the stick are not supplied with electricity, so the stick works but the FFB doesn’t…

Thanks, Banzai, I’ll have a look. Is that under ‘Axis Assignment’?
