Operating the timers using transmitter controls or external switches
Programming examples – Fixed-wing models
If you have followed the model programming descri-
bed on the preceding pages for
Example 1 on page
126 or Example 4 on page 129, or – in contrast to
the programming examples – you are using the Ch1
stick (throttle / brake stick) for power control, then you
can use a control switch to start and stop the stop-
watch automatically.
To assign the desired timer to one of the control swit-
ches G1 to G4, you move to the menu ...

… and select the appropriate line with the rotary con-
trol pressed in. Assign the desired timer to the trans-
mitter control switch you wish to use as described on
page 30.
You should now call up the menu ...

… and select the line for this control switch with the
rotary control pressed in. Press the rotary control with
the left-hand
SEL fi eld displayed in inverse video,
then simply select the corresponding transmitter cont-
rol, e.g. control 1 (= Ch1).
Use the rotary control to shift to the STO fi eld …
… and move the corresponding transmitter control in
the direction of motor “OFF” (e.g. stick back towards
you). Give a brief press on the rotary control to defi ne
the switching point. The right-hand column displays
the status of the switch: above the switching point
the G1 switch (in our example) is “closed”, below that
point it is “open”. The stopwatch in the basic display
now starts when you move the Ch1 stick towards full-
throttle, and stops when you pull the stick back again.
In contrast, if you are controlling your motor with an
external switch as described in
Example 2 or 3 , you
do not need the control switches described above. It
is quite suffi cient simply to assign the stopwatch to
the same switch, so that the timer starts running auto-
matically when the motor is switched on.
Tip:
When using an electric motor, the motor run is usu-
ally limited by the capacity of the battery, and in this
case you would normally set the stopwatch to “count
down”. Simply enter the maximum permitted motor
run in the “Timer” column, e.g. “5 min.”, and set the pi-
ezo buzzer to emit warning tones shortly before the
permissible time has elapsed, e.g. “30 sec” before-
hand.

With the stopwatch halted, press the CLEAR button
from the basic display, so that the stopwatch switches
to the “Timer” function. The timer can now be started
and stopped using the motor control stick.
