10.4 Adjustment of main rotor blades
The purpose of adjustment is to make the weight and gravity center of main rotor blades equally distributing and
ensure the main rotor blades are in same level during high speed spinning.
10.4.1 Color decal (tracking tape)
Two different colored blade tracking decales should be placed 20mm away from each end of blade tip,whose
purpose is to identify the position of each spinning blade in the following inspection of the blade tracking.
10.4.2 Inspection and gravity center adjustment of main rotor blades
(1) Transverse inspection and adjustment of gravity center. Use a bolt to insert the mounting hole of main rotor
blades and screw the bolt cap, and then stretch the main rotor blades in line. Hang the couple of main rotor
blades in the air using the bolt as a fulcrum. If the main rotor blades keep in a horizontal line, it means ok; if
one end of the main rotor blades is higher than the other one, please move the high end stick to the high
direction, and/ or move the low end stick to the high end until balanced.
Mounting hole of main rotor blades
(2) Longitudinal inspection of gravity center. Shown as below, take the mounting hole of main rotor blades as
the fulcrum to vertically hang in the air. If the main rotor blades are almost superposed, it means normal
(shown as Fig. A); otherwise abnormal.

10.4.3 Tracking inspection
Note: for the sake of safety, please keep the main rotor blades of helicopter at least 3 meters away from
the pilot when his inspecting the tracking problem.
Slowly push up the throttle stick of the transmitter and ensure both the line of sight of the pilot and the main
rotor baldes are in the same horizontal level.when the main rotor blades are spinning,please observe whether
or not the levels are superposed in the same level.superposition is correct , otherwise there exists tracking
problem and adjustment is required
Correct blade tracking
Incorrect blade tracking
