What is the best type of grease to use on this if the joystick squeaks
I bought my T Flight 4 HOTAS a little under a year ago and it's been great; however, it has begun to squeak quite a bit during gameplay. Considering that the majority of time spent using it is when the kids and the gf are asleep, this presents a problem. I've looked up other question/answer forums regarding this subject and some suggest lithium grease, others suggest plain old WD-40. I do know how to get to the joint in the joystick to apply the grease but I don't want to kill my device by applying the wrong stuff. Any suggestions? Thank you for your assistance.
