D) The First Landing; Changing Quartz - Reely Christen Eagle Bedienungsanleitung

d) The First Landing

As with the start, the landing must always take place against the wind. Reduce the motor speed and fly in large flat circles. Do not pull too hard on the elevator,
this allows you to reduce the flying altitude selectively.
Fly the last curve before the approach for a landing in such a manner that in case of an emergency you will have sufficient room for landing and so that you will
not have to effect considerable corrections to the course during the approach for a landing. When the model is flying on the planned landing line, reduce the
motor speed further and hold it horizontal using the elevator controls. Now the model must continue to lose altitude and must fly towards the planned touch-down
point at the end of the imaginary landing line.
In this critical flying phase, ensure sufficient flight speed and do not slow down the model by reducing the motor speed too much or by pulling too hard on the
elevator.
Only shortly before the touch-down should you stop the motor and land the model with fully drawn elevator.
After the landing, you can re-adjust, if necessary, the linkages for the rudder and the elevator so that the model flies in a straight line and that the trim lever at the
transmitter is in the center position again.

13. Changing the Quartz Crystal
In order to avoid double channel assignment it may be necessary to change the quartz crystals on your remote control system.
For operational safety reasons, you should only use quartz crystals that are explicitly recommended by the supplier for use in your remote control
system.
To change the quartz crystal, proceed as follows:
• Ensure that the transmitter is switched off and pull the transmitter crystal holder from the rear side of the transmitter casing (fig. 2, Pos. 8).
• Take the transmitter crystal out of its plastic holder. Insert the replacement crystal with a different channel in the same frequency band. Please make sure that
you place the right crystal in the holder. Transmitter crystals are normally marked with the letter T or TX (T = "transmitter"). Put the crystal holder back into the
transmitter.
• Ensure the flight battery is disconnected and remove the receiver (1)
from the holder in the model and remove the receiver crystal (2).
• The suitable crystal for the receiver has to be marked with the same
channel number as the transmitter crystal. In addition, it is marked with
the letter code R or RX (R = receiver).
? Insert the replacement crystal with the suitable frequency for the
transmitter into the receiver.
• Switch on the transmitter and then the receiver and check the function
of the system.
