Tracking adjustment

① Measure the pitch angle using a pitch gauge and make the angle same on both sides of

the main rotor by adjusting the mixing arm control rod.

② Apply the tracking tape to one of the rotor blades.

③ Start the main rotor and see if the rotor blades are tracking properly.

④ If the blade with the tracking tape is up, adjust the mixing control rod by turning its

upper ball link counterclockwise(make a half-turn for each adjustment) until the blades

are in track.

⑤ If the blade with the tracking tape is down, adjust the mixing control rod in reverse way.
