d) Checking and setting the tail rotor
For an exact description of the correct fine-tuning of the tail rotor, refer to the documentation of your piezo gyro. If
necessary, you can optimise the setting by simply shifting the tail rotor servo on the tail pipe.
13. Care and maintenance
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 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 besides the rotor blades. Always check the smooth running of the ball bearings in this context.
The screw attachments may become loose due to vibrations. Therefore, check their tight fit after each flight day.
Experience has shown that this effect often occurs with metal screw attachments.
Also check hard to access components like the toothed belt for the tail rotor drive. The belt may neither be frayed and
all teeth must be tight. You have achieved the right belt tension if you can press one side of the drive belt with a small
screwdriver inwards towards the center starting at the front edge of the tail pipe without using excessive force (also
see ill. 7).
Important!
If you have to replace damaged or worn parts, only use original replacement parts in your helicopter.
