d) Checking and Setting the Tracking
Once you have made all the necessary settings on the transmitter and the mechanics, you can now check the tracking.
Tracking is best checked during flight. Mark one rotor blade at the end of the blade with dark or luminescent tape.
During hover flight at head height, you can see which rotor blade must be corrected. Adjust the accurate tracking of the
auxiliary paddle and rotor blades for the two linkage rods "B".

For display reasons, figure 15 shows a sketch only. With the rotor head used, the control rods "A" are
predefined and cannot be adjusted.

Maintenance and Care
a) General Information
You have to perform regular checks and maintenance work on your model helicopter to ensure its operational safety.
Check the tail rotor at regular intervals. In case of contact with grass or soil, completely remove any residues from the
rotor blades. After each ground contact, check the tail rotor blades for visible damage.
Oil the sliding sleeve on the tail rotor at regular intervals. Test the smooth running of the tail rotor drive as well as the
control.
Check the main rotor head after each flight. The rubber rings in the rotor head lose their elasticity over time and must
be exchanged.
The joint socket of the control may become loose and jump off after a short time in case of improper installation.
Therefore, check its tight fit before each flight day.
If the main rotor comes into contact with the ground, you also have to exchange the main rotor shaft and the blade
bearing shaft in addition to the rotor blades. Always check the smooth running of the ball bearings in this context.
The screw attachments may become loose due to vibration. Therefore, check their tight fit after each flight day. Expe-
rience has shown that this effect often occurs with metal screw attachments.
Ensure that the tooth belt is undamaged and well-tensioned and that the tooth flank play for the engine/main drive
gear wheel is well adjusted. For control and adjustment of the drive parts, observe the following notes.
