Anyone here have an x52 pro? I really like mine for all sims but I've been playing a lot of Warthunder lately and when I make really slow, fine corrections on the stick I can feel the spring popping around. It's not smooth would be the best way to describe it. Sometimes it is, sometimes it isn't. But usually it occurs the most when I'm making real fine, slow adjustments on the stick.

Anyone use grease, wd40, or candle wax or is that a no no?

I've had good results using silicone lubricant "sil-glyde compound" on the metal part that rubs on the plastic.

It's safe on plastic which is key for anything you use on that X-52pro section.

I picked mine up at the local autoparts store, but I see it online here:

picked up some Silicone grease from auto store. So far so good. MUCH smoother when making fine adjustments and small inputs and holding turns and pitch. Now I just hope it lasts long and doesn't dry out.
