(4) When blades are too loose in the grips, the blades shake due to excessive clearance or the blade grips are distorted.
When the main rotor blades tracking is incorrect, the ball linkage connected to the higher blade should be shortened (to reduce
blade pitch) and/or the linkage on the lower blade should be lengthened (to increase blade pitch). Take care not to unscrew the link rod too far from the ball connectors.
If the main rotor blades appear to be normal at low speed and abnormal at high speed or abnormal at low speed and normal at high speed, please check the grips for distortion or excessive clearance. If the blades are loose, please tighten the grips,if the grips are distorted please replace them immediately. Only by repeating this process and making small adjustments is it possible to avoid tracking problems.
When there is a blade tracking problem the lengths of the ball linkages need to be adjusted. If the high blade has the red decal, please decrease the length of the ball linkage of the red blade and/or increase the length of the blue blade's linkage. If the high blade has the blue decal, please decrease the length of the ball linkage of the blue blade and/or increase the length of the red blade's linkage.
