16.15 STOPWATCH
The Stopwatch menu is used to set up and adjust the electro-
nic timers provided by the FX-40 transmitter. The timers are
displayed in two on-screen windows, which means that you
have constant access to two crucial times, for example: the
overall flight time and the motor run time of an electric-powe-
red model. The timers can be set up individually for each
model. The pre-set configuration is automatically loaded when
you switch from one model to another.
For each timer you can select either of two operating modes -
count-down (‘down’) and count-up (‘up’). If you choose a
count-down timer, you can enter a maximum flight time for
each model, e.g. according to the volume of the fueltank or the
capacity of the flight battery. As soon as you start the timer,
the time begins counting down, starting from the initial value
you have entered. The remaining residual time is constantly
displayed in red figures.
In contrast, the count-up timer starts at ‘0’ and displays the
time which has elapsed since it was started by operating the
switch. In this case the numbers are displayed in black. For the
last twenty seconds of the period the transmitter emits an
audible signal every two seconds. Over the last ten seconds of
the programmed time a signal sounds every second. When the
set time is reached, a continuous tone sounds for several
seconds. The timer then continues running, but with a nega-
tive prefix.
Mark the ‘Stopwatch’ option in the base menu. The screen
display now looks like this (in the screen shot certain settings
have already been entered):
Working from this main Timer function menu, you can start or
stop the selected stopwatch by touching the display field.
Operating the ‘Reset’ button resets the screen display.
However, the main purpose of the two timer frames is for pro-
gramming the stopwatches. Marking the field in the ‘Mode’
line toggles between the count-up (‘up’) and count-down
(‘down’) functions of the timer. The start or finish time of the
stopwatch can also be programmed in the same line. When
you touch the corresponding field, the arrow buttons can be
used as a convenient method of setting the required period for
a count-down timer in minutes and seconds.
With the timer configured in this way, you can move on to defi-
ning the switches which are to be used to control the timers. In
each case a switch can be assigned for:
• resetting the timer (‘Reset’)
• starting the timer
• stopping the timer, and
• recording lap times (individual time).
Marking the appropriate switch field calls up the switch select
menu on the screen. You can now define a switch and its
direction of operation using the procedure which should by
now be familiar.

The default set-up is no switch, and the screen displays
‘NONE’. The same switch can also be assigned to individual
options of the timer function.
When you define a switch for recording individual times (lap
times), an additional ‘List’ field appears. If you now operate the
‘lap time’ switch while the timer is running, the stopwatch sto-
res the elapsed time to that point. This provides a means of
recording the times for particular phases of a flight, e.g. indivi-
dual lap times in a pylon race.
The lap times can be displayed on-screen by marking the ‘List’
field in the Timer display: the ‘stopped’ times are listed in the
display which now appears. The screen-shot below shows this
display.
Marking the ‘Reset’ field of the associated timer function resets
that timer, although it is also possible to define a switch specifi-
cally for that purpose.
