This tool is to remove unwanted CCPM interactions when you move throughout your pitch range. CCPM interactions are introduced because no two servos are exactly the same, even the most high quality servos will still act very subtly different from servo to servo. With the radios of today it is easy to adjust these interactions out with this tool using end point adjustment a.k.a. travel adjust on the cyclic servos channel. This simply cannot be done accurately by eye and the difference is easily felt after using the Lightning Power Swash Plate leveling tool.
