Hey Tony,

It seems like you have the first generation Kyosho Plasma. The second gen is the one with revamped parts that have dots them to locate what direction the pivot balls must be inserted into the arms ect.

I checked the bulkheads, checked the arms, checked everything and all seems OK.. I've taken all these measurements using digital calipers on a flat surface. Measured the bottom of the arms, and measure the top, measured to the top of the ball. Same result.

To compensate for this I used a 0.5 mm shim on the lowest side to rise it up 0.5 mm, this has helped with the issue. I very well may look into another set of bulkheads and see if it makes a difference or not.
