I picked up an FGX recently and I'm having an issue where the ball in the Exotek top arms is very stiff and I cannot get it to be free. Does anyone have any suggestions on freeing this up as it looks to be creating some binding in the arm/steering.
I have warmed the arm and removed the ball and then made sure it was clean. I have even buffed the ball to be smoother but still no joy. When the arm is warmed it moves better but when cool it is stiff.
I believe the balls in it are the 3racing balls and I have not tried a Tamiya ball. Would this be the solution or is there something else?
