Rotate the screw clockwise -> higher spring tension

Rotate the screw anti-clockwise -> lower spring tension
The white arrows in the illustration indicate the adjustment screws;
the screws on the inside adjust the horizontal stick functions.
Throttle ratchet function
The transmitter is supplied as
standard with four self-
neutralising stick functions. The
ratchet plate is fitted in such a
way that the ratchet has no
effect. The illustration also
shows how the spring tension
adjustor screws are accessed
when the ratchet plate is fitted.
One of the two vertical control planes can be converted to ratchet
action to cope with functions for which a self-neutralising action is
not required. In this case the stick stays at any intermediate position
in the fore-and-aft plane, instead of returning automatically to the
neutral position.The ratchet is generally used to control the throttle
of a glowplug motor and similar functions.
If you wish to engage the ratchet spring, the ratchet plate must be
mounted on the corresponding stick unit as shown in the
illustrations below.
-
First undo the two screws (
A
) and remove the ratchet plate.
-
To place the throttle function on the
right stick, the plate has
to be rotated through 90º to the left, and mounted on the
left-hand stick unit
(as seen from the rear).
-
To place the throttle function on the
left stick, the plate has to
be rotated through 90º to the right, and mounted on the
right- hand stick unit
.
-
To do this, press the return rocker of the stick unit down using
the pin (retainer, on the back face of the plate). The rocker is
located directly adjacent to the outside spring adjustment
screw; it has a spring attached to it.
-
Place the ratchet plate on the stick unit screw dome in this
position, and re-fit the screws.
-
The pictures above show the final installed position of the
ratchet plate.
4.4 CAMPac model memory modules
The transmitter’s model memory capacity can be expanded by
fitting "CAMPac" modules. Various CAMPac modules are available,
offering different numbers of additional model memories:
4k
CAMPac 3 model memories
No. F 1508
16k
CAMPac 12 model memories
No. F 1509
64k
CAMPac 49 model memories
No. F 1566
The CAMPac module is plugged onto the pin row with the
appropriate legend on the circuit board inside the transmitter.
Switch the transmitter off. Carefully
insert the module with the legend and
lug on the module matching the
diagram printed on the circuit board
itself.
CAMPac modules have to be "initialised" when they are first
plugged into the transmitter.
The screen initially shows the
message "CAM 49", confirming the
memory size of the CAMPac you have
fitted.
To prevent accidental over-writing of
CAMPac data, a flashing "
OK?
"
appears on the screen, requesting
confirmation.
Press the
"S" button
to start the initialisation process.
The initialisation process commences,
and the screen counts down the
possible number of model memories
as it proceeds. In our example a 64K
CAMPac is fitted, containing 49 model
memories. Once the count-down has
reached zero, the beeper sounds to
indicate that the process is completed.
The CAMPac module is now ready for use in the FX-18.
The CAMPac module is formatted using the FX-18 format.
If you ever wish to use it in a different transmitter type, you will
need to re-initialise the module. This process erases the FX-18 data.
Individual CAMPac model
memories which have not
been
assigned a name are indicated by the
letter
"E"
and a sequential number.
The
"E"
stands for external model
memory.
4.5 Changing crystals
Within the fixed frequency band the transmitter and receiver can
be operated on different spot frequencies (channels) by changing
the plug-in crystals. The crystals are located in sockets in the
transmitter and the receiver, and must be changed together.
