How To Change Frequencies; Corrective Action - Carson APACHE 4 CH Manual De Instrucciones

How to change frequencies

Make sure that nobody else is transmitting in the proximity of your frequency!
Interfering signals on the same frequency can make you lose control over your model.
If you are flying with other RC users, it might be necessary to change the frequency.
Transmitter
A rapid change of frequencies is possible simply by unplugging an interchangeable crystal on the back of the transmitter and
then plugging in another one.
For reasons of operational safety, employ only crystals recommended by the suppliers explicitly for use in your remote
control system.
Transmitter
Remove the holder for the transmitter crystal from the back of the transmitter housing of a switched-off transmitter.
Set the crystal replacement with another channel of the same frequency band. Pay attention that the correct crystal is
employed. Transmitter crystals are as a rule characterized with the letters T or TX (T = Transmitter).
Receiver
Plug in an interchangeable crystal into the receiver for a rapid change of frequencies.
The suitable receiver crystal with the frequency suitable to the transmitter must be labelled with the same channel number
as the transmitter crystal. It additionally bears the identification letter R or RX (R = Receiver).
Now take the transmitter and subsequently the receiver into operation and check the functioning of the equipment.
Do not mix up the transmitter and receiver crystals!
The transmitter and receiver crystals must be of an identical frequency.
Make sure that the crystal is fully inserted in the transmitter and receiver, not partially.

Corrective action

The rotor blades of the two principal rotors have the largest influence on the flight characteristics of the helicopter.
Very often one can attain a major improvement of flight behaviour simply by exchanging one or more rotor blades. There is
an especially serious difference between balanced and non-balanced rotor blades. If the model does not show a balanced
flight behaviour, then at first the balancing state of the rotor blades should be inspected and corrected and if necessary the
respective blade should be replaced.
The track running of the rotor blades also has an influence on the flight behaviour apart from the balancing state. Both
rotor blades of a rotor rotation travel exactly in one plane if their track running is correct. If this is not the case, vibrations
arise which adversely affect the flight behaviour.
To check the track running, mark a blade tip with colour and observe the corresponding rotor rotation from the side.
If the marked and the unmarked blade apparently "overlap", then the track
running is correct (1).
Otherwise you will see both points at different heights (2).
