Notes:
Be sure the throttle servo does not run out
mechanically when the cut-off function is
activated.
A threshold over +100 % is reached by temporarily
increasing the travel for servo 1 in the »Servo
adjustment« menu to over 100 % then, after
storing the threshold, change servo travel back to
the original value.

When a switch, a control switch or a logical switch
is assigned in this line as described in the section
"Assigning transmitter controls, switches and control
switches" on page 60, the respective switch or control
position will be polled and an appropriate warning will
be blended into the basic display under some condi-
tions.
In combination with logical switches, almost any
switch setting can be called up for transmitter switch

The "Auto trim" option makes it possible to trim a
PPM10
model quickly and without complications, e. g. in the
context of a first-flight or even after (major) repairs, etc.

Typically such test flights are initially flown with sticks
–––
counter operated until the desired state of flight is
SET
achieved. This generally involves working the trim con-
trols during the flight to "unburden" the sticks.
This is exactly what the "Auto trim" function is for.
After the desired flight attitude has been achieved via
control functions 2 ... 4 (aileron, elevator and rudder),
the switch assigned to "Auto trim" – ideally one of the
standard-equipment momentary switches in the switch
panels – is to be activated ONCE.

Program description - Base setup models | Winged models
At the instant the switch is activated, the stick offsets
from their neutral positions will be determined and
adopted as trim values. However, this does not take
place instantaneously but rather within about 1 second.
During this period after the switch has been activated,
the sticks should be returned to their normal positions.
Important notes:
Use safety reasons by no means the "Auto
Trim" in default of "0" trim steps in the
same column of the menu "Stick mode"
0
(page 114).
Be sure that during the switch assignment,
the sticks for aileron, elevator and rudder
are in their neutral positions as otherwise
their offsets from neutral will be adopted right
away in trim memory as the trim value.
Since EVERY activation of the Auto trim
switch has a cumulative effect, after
concluding an "auto trim" flight, the
assigned auto trim switch should be deactivated
for reasons of safety. Otherwise there is a residual
danger that the "Auto trim" function could be
activated accidentally.
Never send a "normal" toggle the Auto-
trim function to or watch out embarrass-
ing that this is provided immediately after
triggering an auto-trimming process again to
"OFF"! OTHERWISE PRESS ANY SWITCH
WILL SOLVE ANOTHER AUTOTRIM OPERA-
TION.
