Mako,
check the forums about Logicrap - I got one when I first started - lasted 2 months - wouldn't hold calibration - spikey pots - had to trash it.
Unfortunate as the stick is well designed and fits and feels good- just the lousiest chapest components possible and didn't hold up at all.
I've since gone CH and there's no comparison. I originally didn't like the stick (it's a strech to grab the hat) and the motion was much "looser" than the Logi. I've since grown accustomed to both and can't praise the quality enough. I can't recall the last time I've calibrated. If the other accolades about CH products I've read here are 50% accurate - I anticipate 5-10 years of troube free service from my current rig.
Sorry, but in my opinion you prolly need to replace the stick.
Regards,
Optiker
