"Stop (watch)" or "Motor (runtime)"
Both of these two timer variants can be started and
stopped using any of the available switches.
The timer defi ned as "Stopwatch" or "Motor runtime"
sums the "ON" times continually, so that once your
aircraft has landed, you can read off the sum of all
switch "ON" times since the timer was last reset.
"Flight (time)"
This timer is designed for measuring the fl ight time: it
can be started with an assigned switch and stopped
(once the switch has been re-opened) on the basic
display by tapping the center ESC key on the left touch
pad. Once in a stopped state, it can be reset to its
starting value by tapping the  or  keys on the
right touch pad at the same time (CLEAR).
If you wish to assign a control switch, you must fi rst
defi ne the switch on the "Control switch" menu and
specify the switching point along the travel of the
transmitter control. As an example, the timer can then
be started by "opening the throttle" or by opening the
throttle limiter for heli models.
Note:
The combination of the fl ight time timer and stopwatch
means that you can glance at the display at any time
and see how long you have been fl ying since the timers
were started, plus the total motor runtime within this
particular period of fl ight time.
"Frame(time)"
The timeframe timer is intended primarily for use by
competition pilots, who are frequently given a timeframe
within which they must complete certain tasks. The timer
is started in precisely the same way as the fl ight time
timer. To stop the timer, fi rst ensure the timer switch is
at its OFF position. Then, press and hold the arrow keys
,and then press the center
Switch assignment
Using the arrow key  on the left or right touch pad,
move the marker frame next to the triangle as shown in
the screen image shown below to the rightmost column
of the relevant line:
Model time 12:34h
Batt. time 1:23h
Top : Stop 0s
Centr : Flight 0s

Here, you assign a switch as described in the section
"Assigning transmitter controls, switches and control
switches" (page 52).
Typical application:
The "stop watch" and "fl ight timer" are both to be started
simultaneously using the C1 stick as soon as a user-
defi ned switching point is exceeded.
For this purpose, you will defi ne e.g. "C1" on the
"Control switch" menu (page 123 ). To complete the
procedure, you select this from the expanded switches
(see the section "Assigning transmitter controls,
switches and control switches" on page 52) and assign
it to both these lines:
Model time
Batt. time
ESC key.

The stopwatch will now stop when the stick is below the
switching point and resume running above the switching
point. The same is not true for the fl ight time timer,

however, which also starts the fi rst time the switching
point is exceeded. It can be stopped (by tapping the

center ESC key on the left touch pad) only once the

stopwatch is stopped; it can then be reset to its starting
value by tapping the  or  keys on the right
touch pad at the same time (CLEAR).
