When necessary, the selection keys can be used
to access and read the sequence of switching
times.
Application:
Measurement of (e. g.) flight phases with in-
creased motor speed, if the same switch is used
to actuate flight phase switching.
• Time2
This timer stores both the “off” and the “on” peri-
ods for the associated switch, i. e. every switch ac-
tuation in either direction will cause a record to be
written for the timer, the timer will be reset then
starts incrementing by “1” again as time passes.
Each time count can be suspended with the cent-
er ESC key of the right four-way button, without
actuating the switch itself. Activating the switch, in
turn, increments the counter by 1 and restarts the
“Time2” timer.
In order to read out the time memory with the se-
lection keys, the “Time2” timer must first be sus-
pended by using the ESC key of the right four-way
button.
A simultaneous tap on the  or  keys of the
right four-way button (CLEAR) will reset suspended
timers shown in the basic display.
Column “Sw. time”
When you switch between flight phases, it is advis-
able to use this column to program a switch time for a
“soft” transition INTO (!) the respective phase. Accord-
ingly, there is also an option for specifying a different
time for the switchover from any phase to, for exam-
ple, Phase 3 than for a switchover to Phase 1.
However, for reasons of safety, transition into the
autorotation flight phase should ALWAYS be set to
switch without any time delay. The arrow “->” in the
column labeled “Sw.time” at the end of the “Autorot”
line indicates that a delay can be set when transitio-
ning FROM (!) autorotation INTO (!) another phase.
Use the  selection key of the left or right four-way
button to move the marker frame to the right beyond
the “ph.Tim.” column:

Following a brief tap on the center SET key of the
right four-way button, the switchover time value in the
field displayed in inverse video can be changed within
a range of 0 and 9,9 s.

AutorotAuto
A delay of 5,5 s applies when switching FROM auto-
rotation into any other phase. A delay of 0,0 s always
applies when switching TO auto-rotation.
The switchover time from any other phase to Phase 1
«normal» will take 3,0 s.
When switching from e. g. Phase 1 to Phase 3, the
switch time is set to 4,0 s.
Such asymmetric transition times can be useful when,
e. g. switching between extremely different flight phas-
es, such as between aerobatics and normal flight.
A simultaneous tap on the  or  keys of the
right four-way button (CLEAR) will reset the time in
the currently active value field back to 0,1 s.
Note:
The “switch time” set here applies uniformly to all
settings that are specific to flight phases, and thus to
all mixers activated in the »Helicopter mixer« menu,
see page 188. Accordingly, the transition between
flight phase-specific mixers does not occur abruptly.
If you want individual servos to be switched without
a delay, however, define these accordingly in the
»Non-delayed channels« menu, see page 161,
which is available as standard on the
mc-20 HoTT
transmitter only.
