【Items which need to be readjusted after the test flight】
Tracking Adjustment
This is to adjust both Main Rotor Blades to the same pitch, so each produces the same amount of lift. If they are not
uniform, their trajectory is not seen as an identical line as shown in the figure below. This leads to vibrations and a
helicopter which does not fly well. When the helicopter is about to leave the ground, look at the plane of rotation of
the Main Rotor Blades from the side. No adjustment is required if the trajectory of the Main Rotor Blades is seen as an
identical line. If vertically misaligned, pitch adjustment on one blade is required. On either the 'high' or 'low' blade adjust the
Universal Link of the rod shown in the following figure in such a manner that the blade pitch is increased or decreased as
required.
Tracking adjustment is dangerous. Remain at least 5m or more from the helicopter at all times.
