This is an optional upgraded Align Counter Thread Main Linkage Rod Set. The linkage set works like a typical turnbuckle linkage in that you can make adjustments to the length of the linkage rod when installed without needing to remove the linkage rod from the helicopter. This adjustment is done by holding the center square part of the rod, and rotating clockwise or counterclockwise to shorten or lengthen the linkage.
