Pivot and side links are free and not binding. Any ideas i'm stumped?
Many 1/12th scale pods I've worked with develop some tweak during the assembly due to the tightening of the screws. This is most prominent on pods that use a tube across the back of the pod for bracing because you turn the right side screw down to tighten and the left side screw up. The trick is to assemble the pod on a flat pit board pushing down on it so tightening the tube doesn't tweak the pod...and also not over tightening it. Cars that use a carbon fiber rear brace with 4 screws have less of a problem but it can still be there because the screws all rotate the same direction on the back.
Old school cars had a top plate that went all the way around the pod so they didn't need the brace...make me wonder if maybe we shouldn't to back to that style pod.
