Lymark Posted April 3, 2019 Posted April 3, 2019 (edited) I sandpapered, greased(767A) as well as replaced the O-ring last month, It felt really smooth and all up until today. I've started feeling a noticeable grinding in all four directions when the stick is near the center, and it makes flying with small adjustment very uncomfortable. I can even feel the small vibration caused by the grinding when I touch the base. It was my first time doing all that, so I assume that I either didn't apply enough grease or missed some spots, in which the plastic gimbal is now grinding against the base? If so, I'd like to know which part of the gimbal is responsible for the center area, so I could be sure to grease it real nice this time. Thank you! Update#1: I just disassembled the base, the large spring seems to be the culprit, as the grinding goes away when I remove it. Maybe I needa grease the spring too? Update#2: Yep! Fixed it by greasing the large spring like there's no tomorrow. Hopefully it will last longer this time. Edited April 4, 2019 by Lymark
