After a full install from Win 32 bit to Win 64 Bit I noticed the response was non linear now. Windows drivers seem to have a small fixed amount of exponential programmed in?

I have installed the CH drivers hoping to resolve this issue and also because when my system takes a sleep, it drops the stick. I'm in the middle of trying to see if loading the CM will resolve this issue.

In short, after my reinstall to 64bit, there were defiantly some stick feel changes similar to what you are seeing. Still working on resolving these myself.

I recall some discussion on the CH forums eons ago about CH calibration. they ade it quite clear that if you intend using CH manager then don't ever calibrate directly in Windows. (It was in the time of XP mind you). A utility exists to delete the windows calibration.

I have been using CH and CH manager for years with zero issues. Having been down the Cougar trail ..Uber next mods etc I switched to CH and never looked back. The stick and throttle are at least 4 years old and never missed a beat, or spiked or reduced sensitivity.

Only changes I have made are the Ivankuturkokoffrubberband mod. A 5 min job that allows you vary spring pressure in each axis independently as the only fault imo in the CH stick is its a little to light. With this my elevator pressure is about 1/3 more than Roll pressure which i have about twice as stiff as stock anyway. The mod is "Fail passive" and I get about 6 months out of a set of bands.

hey IvanK...do you have a link to that rubberband mod?i searched in google but didnt find anything related to it except your post.

You can't do this under Win 7 64bit, it won't let you :)

i think you can....
i started a thread about the same topic over at ch-hangar and bob gave me the advice to clean the windows calibration with this tool...

quote by Bob Church:
"....
http://www.wingmanteam.com

and look on the main page for a utility called ClrCalib.exe. Download that and run it, it wipes Windows calibration data clean and should clear up the conflict."

Sure David its my mod. I will dig out some images etc tomorrow and post here.

thx very much....that would be really kind of you...thx in advance

Last night I think I found Ivan's original post with pics at http://forums.eagle.ru/showpost.php?...28&postcount=4

Yes thats it. I post again here the same stuff for those that dont want to go to the link :)

The world famous Ivankuturkokoffrubberbandmod. I came from a Cougar then Cougar ubernxt so know the issue. I knocked off the Condom mod idea and used standard Aussie newsagent rubber bands. I run 2 size 12 bands in the pitch axis and a single no 12 in the roll axis. This gives you a little more stickforce in Pitch compared to roll which is nice. In each case I put a single Double twist in each band. Just make sure that bands go inside the support. Incorrect and correct routing shown in the jpgs below. The incorrect routing works just fine btw but band failure occurs a little more often

This mod is straight forward and is fail tolerant. I get about 6 months in the Pitch axis and forever in the roll axis. There is no problem with safety or risk in damaging the stick as the bands oppose the jaws you can see this in the top A labelled jpg below..... no strange smells either. Also no issues with calibration as again the bands oppose the jaws so will auto centre everytime. Even better it is fully adjustable want more tension just add another band to suit your tastes.

Its fail tolerant so when one goes the stick still works. It takes about 5 mins from go to woe to do the mod.


Here are some images ... all you need:

You need to unscrew the bottom of the CH stick (caution if you are still under warranty you will void it). There are screws under each of the rubber feet that can be popped off with a screwdriver as they are just tacked on with glue. An additional screw is located under the "don't open me or you will void your warranty" sticker.

thx IvanK...i will definitely try your mod.
