I think the "permanent fix" is going to be an aftermarket upgrade in the same vain as the Cougar. As a follow up to my post a few days ago, the pots are now totally shot. They have zero response at full throttle, and are jumpy at low throttle. This is disappointing to say the least. Upon opening the upper right hand throttle, I saw root cause of the issue: The pot for the R2 trim has wiggle room. Poking this Pot caused the trim to jump all over the place in the calibration software, recreating the issue so many have complained about. It's not a case of defective product, it's defective engineering. The best fix I can think of would be to solder in an extension to the entire wire bundle. Then glue a section of the wire to the inner housing of the throttle lever, and another section to the throttle housing. The result would be to isolate the movement of the wire down to just the wire extension.


Of course, I'm open to other suggestions.

An email I received 4 days after I sent my inital complaint into "logitech" (in quotes b/c they out source all their tech support)

"Thank you for contacting our Logitech Technical Support. We are sorry to hear that you are experiencing problems with our product.

From your description of the issue, it appears that your G940 is defective (hardware fault).

In this case, if the product is still within warranty, we advise you to contact your reseller (the shop in which the mouse was purchased) to claim warranty replacement (in the UK reseller's warranty is limited to 12 months and the reseller is required by law to replace any defective products within this period of time). If it is out of the reseller's warranty, you can still make a warranty claim on the basis of the manufacturer's warranty.

Your G940 has a 2-year manufacturer warranty.
If you have any other concerns regarding your product or you have any further questions, please feel free to email us back."

Not sure what my mouse has to do with all this...

Another fun fact: Apparently the English break things a lot, since it only has half the warranty there...

I can also confirm that removing the screw holding the r1&2 pot wires down solved my spiking issues. Mine began a week or two after I got it and grew to a point where almost any change in the throttle sent the pot flickering wildly, which was really annoying in fc2 as I used the pot on the side of the right throttle for zoom. Now it is perfect, and noone would even know I'd been in there. Shame we had to solve this little blunder ourselves, but I didn't feel like sending my throttle back and waiting 6-8 weeks for another unit that might do the same thing within a week. Atleast this way I threw the can in the trash.

Good luck this time, mates!

pato.

Thanks Cason, Thud and Hrvje for your "fix". I had no problems with my G940 but decided to look at the R1 and R2 Wheels. I saw what the rest of the people here saw. When I idled the throttles the two wheels spiked badly. It took all of ten minutes or less to fix the throttle and put it back together. If you can follow instructions and use a screwdriver(get one with the right tip) you can do this. Hrvje's excellent illustrated instructions are awesome and should be a sticky.

There is my two cents for the day.

Thanks guys.

Nice fix! Bye bye spiking!!

Damn! The spiking is back. I am thinking of making the wire longer so it dont pull on the white connector....

Fixed my spiking, thanks a lot for instructions.
