I had been flying with a saitek x52, I loved it, but I decided to upgrade. I got a Logitech G940, I love the system and it flies well, I only have 2 problems with it, both are just irritants. The first is that the stick keeps losing it's calibration, a lot more than my X-52 ever did. The second is the auto pilots will not stay engaged, it will stay on for a few seconds and then kick out. Even if I trim it out and get the turn and bank indicator centered with the ball not moving. Any help would be great.

most likely your stick is spiking. Open the "map controllers" section then click on the joystick in the drop down. Watch the numbers along side of the x,y, and z axises. if they are jumping all over the place thats your trouble.
Increasing the "deadband" might help clear it up.
This was the biggest reason I threw away my logicrap stick years ago and vowed never to buy another. They are "sloppy" out of the box and just never stayed calibrated for me.

Thanks Fugi I will try that as soon as I get back to the house. That was one he'll of a fur ball last night huh?

I died in a bunch of them last night, which one you talking about? :devil
Had a few good fights last night :aok

I don't have any calibration issues with my G940 but the auto pilot problem is because it doesn't have a centering spring action. The slop in the center makes it difficult to have the stick centered well enough to keep in in range of auto pilot operation. Unfortunately there is no way to adjust how much the stick can move before it turns off auto pilot in Aces High so you're stuck with this problem.
That used to annoy the heck out of me when I first got it but now I've gotten used to it.. it's just a matter of balancing the stick in just the right position and looking one last time as you walk out of the room to get a beverage to make sure you aren't pointing nose down into the ground...
When you calibrate it make sure you actually have the stick centered (and not just let go of it) otherwise it will calibrate the wrong position as being center.
Also make sure you have the newest firmware installed (Located HERE (http://forums.logitech.com/t5/PC-Gaming/G940-firmware-1-42-is-now-available/td-p/542496)) as it almost completely removes the hysteresis (also known as the reversal bug) from the stick's X/Y however this will still happen in all other axes (including trims, rudder, throttles, etc). If you don't know what I'm talking about refer to this demonstration video: http://www.youtube.com/watch?v=SZlUWwOJUN0 (http://www.youtube.com/watch?v=SZlUWwOJUN0)
If/when (with emphasis on the WHEN) you start seeing spiking issues in the throttle plan on rewiring the throttle. It starts out with the throttle trims dropping out as you move the throttle and eventually makes buttons quit working, etc. Its wiring is a little to fine and the harness is a little too short and they all tend to break.
Also if your rudders spike you can replace its pot with a quality CH pot. It's a pretty easy replacement.
If the hysteresis becomes too annoying you can always rewire your stick and rudders through a third party controller (I used a Bodnar BU0836 board). The hysteresis is a failed attempt by Logitech's engineers put in place at the firmware level to help to compensate for gradual wear and jitter/flicker from the pots. Unfortunately they failed miserably and accuracy takes a huge hit in the process. If you want to see more details about my modification feel free to read about it HERE (http://simhq.com/forum/ubbthreads.php/topics/3323724/G940_MOD_Warning_large_picture.html).
I will warn you this stick is really neat but has a lot of well known problems and Logitech quit supporting and developing it completely. After they released the final firmware almost a year ago to this day no updates have been released and no one will talk about it. It's kind of like they just want it to go away. They'll still honor the warranty and replace your unit with another flawed product but don't expect anything else from them.
While I love mine unless you want a project my advice is to return it for a refund if you can and run away... as fast as you can! If you want to play around with it some then it can become a very nice stick.

I really wish I had seen this info before I bought the Logitech G940. I thut I had done some really good research. So far I am not having throttle problems yet. Since I have had it for a year, I guess that I am going to start looking forward to doing this. Good thing that I kept my X52. So I can still fly while I am working on the 940. The X-52 is just bullet proof I guess.

I went from an X-52 to the G940 as well. My five year old X-52 is sitting in the closet but still working just fine (especially after doing the magnet mod) but the force feedback with the G940 was just too cool to give up on it.
I waited a whole year until my warranty was up before tearing into my G940 and making it right. I wish I had done it sooner. I paid about $40 for the Bodnar controller board and about $10 for various adapters, wires, solder, etc and just went at it. I left the buttons alone but rerouted the throttle and rudder axes to the Bodnar board. I didn't touch the stick itself.
About a week after doing the modification my throttle started acting wonky. I suppose disturbing and rerouting some of its wires caused too much fatigue and then the wires started breaking - my biggest symptom was losing the buttons behind the throttle unless it was less than 90% (or so) throttle. I tore it apart again and replaced the main harness with two strips from a floppy cable and soldered it all together. This was also the time I mounted my Bodnar board into the throttle base itself so I now have a cable coming out of my stick (that goes to the throttle), another cable coming out of my stick (that plugs into USB) and a 9 pin connector at the stick that my rudder pedals plug into.
It's also cool because since the buttons still go through the stick they can all still be programmed with the Logitech software.
Anyway let me know if/when you decide to do the mod I'll be more than happy to offer my assistance.

Thanks a lot trigger I will let you know, the write up at the link was great.
