after about 1800 hrs the joystick seems to be developing some new features - the "neutral" return position has developed a lot of play and when resting my hand on the stick it now slips into a roll, like there are 2 home positions - one a left roll, the other a pitch and right roll - with no real feel for the neutral position anymore. I've watched the complete disassembly on youtube and the O-ring looks easy. I'm sure I could get the gimbal apart, but I wouldn't want to bet on getting it back together. Does this sound like a O-ring prblm or should I be looking for a replacement stick?, $300 a pop for a stick is a bit steep.
