Main rotor blades that are out of track with one another can cause vibration, instability and a loss of power due to
additional drag.

at eye level from a safe distance (approximately 15 to 20 feet (4.7 to 6 meters)).
Note which blade is running low (by colored tracking tape) and increase the pitch of the low blade one turn of the
ball link at a time until each blade runs in track (on the same plane).
Please refer to the diagrams on the following page to identify the dierent tracking situations, as well as methods to
mark each rotor blade for tracking identication.
