Yes, for AAR, just like for a helicopter or any time you want the most precise joystick control, any FFB stick will tend to be better than a sprung stick because they are so light and easy to move around the center point (no X or Y crossing notches which cause hesitation as you move the stick). So regarding the G940, the issues are not precision for movement (x/y pickup by the pots or hall effect sensors). The issues are lack of precision for the FFB which is a little frustrating when it comes to holding the stick with magnetic brake on a helicopter. But in AAR, you will have your hand on the stick constantly and sloppy FFB isn't an issue.

For the POV, not sure which you one you mean. The lower POV hat is a 4 way button like most POV hats, and you can assign anything you want to it either in DCS, or in the Logitech Profiler software (v5.10.127 is the last version to support the G940). For the upper POV (called the mini-joystick), this is an analog X/Y mini-joystick. You can assign it to any DCS control that works with an analog axis (many DCS aircraft allow analog axis to control targeting cursors, etc.), or in the Logitech Profiler software, you can assign zones which will perform keyboard keypresses which turns the analog mini-joystick into a 4 way hat.


yes sorry i intended the pov axis...i wish to use that as a trim in the f18
....so i should use the logitech profiler to achieve that..thanks

... i just registered to share my latest firmware patch, which aims to fix the strange hyterese behavoir of all the 8-bit axes (reversal bug) and to remove the rudder firmware deadzone.

If someone want to give it a try?

https://github.com/fred41/G940-firmware-fixes

This patch is based on the latest inofficial firmware 1.42 and you need logitechs firmeware updater 'G940_Update_FW0142.exe' for uploading.


Please let me know how it works, thanks.

Hi fred, I recognized that reversal bug mostly with the throttle axis. I just gave it a try. The throttle seems to be pretty precicse now. Thank you very much. Did it took a lot effort to fix this?

Hi,


thanks for testing and feedback.

Yes it was a challenge to understand the machine code and its problems. But it was a very interesting lesson too.

As for the throttle, there is a simple mechanical modification, to significantly improve the precision:

There are 2 holes in the plastic with a diameter to big for the axes (M5 screws). I just used a 0.8mm wire, to bend a ring from.
This ring fits exactly between the M5 screew's and the plastic holes. Works very good for me.

Fred - you are awesome!

I have been using the G940 since it came out and fixed the cable way back when and applied 1.42. Since then I have been using it as there are no other alternatives for us that reqire FFB (I naturally have an MSFFB2 in my closet). As an old IRL pilot of gliders and small prop planes I simply cannot live without FFB...

But after looking for new fw patches for years after 1.42 I realized that I had to live with the throttle reversal bug. Just yesterday I started thinking about getting a Warthog throttle and keep the G940 stick - and came to this forum to see what other alternatives that might be available. Found this thread and got your patch smoking from the oven

And it really does a big difference! Now the throttle is GOOD! To better see the input I loaded up IL2 where you see the % of throttle when changing. I have previously been trying to set it to exactly 80% for formation flying etc. It has been a royal pain in the ... Now I just sat there with a smile going from 70% to 80% to 90% and then quickly back to 70% And I can nail it directly. Sat like a silly child doing it for 10 minutes! And have not realized the problem with the hardware deadzone of the rudders. Love that you have removed that as well.

This REALLY needs a separate post in every flight sim forum for the few of us that still use the G940. But please - wait until I have bought a few on eBay that I can sell expensively after the news get out

Again - a really big thank you for your effort!

Hey fred41!


That are really awesome news! For years I was holding out for the next force feedback stick. Last month I caved in and pre-ordered a VPC gimbal and bought a Warthog HOTAS. Now you are coming out with a fix for my main issue with the G940. Bad timing, story of my life!
Nevertheless I'm more than happy that the G940 finally gets that bit of love it deserved all along!


Now the only thing left to optimize is the center play. Any of you guys have a fix for that? Flying helicopters I mostly do all my movement within the center play of the stick. Curves and deadzones are now solution since DCS doesn't account for the moving center position when trimming, as far as I can tell.


Once again, great work Fred!
