The maximum delay time is 25 seconds, and the
value can be set separately for both directions.. The
time statement always refers to full servo travel, -
100% to +100% (=200%). For example, if you have
set 20% elevator trim compensation for the SPOILER
mixer input, then the elevator moves to the new set-
ting in 2.5 seconds.
Example:
Compensating for an unwanted pitching moment due
to incorrect motor downthrust (model climbs when the
throttle is opened).
The mixer ELEVATOR+ has been set up with
THROTTLE as one of the inputs. This provides a
means of correcting the model’s unwanted tendency
to climb when the throttle is opened. Nothing new
there.
What is new is that the „slow“ mixer can now be
added. Naturally the model’s unwanted pitching mo-
ment builds up gradually, i.e. it follows the model’s
rate of acceleration. Even if you use a switch to open
the throttle (electric motor), it can take several sec-
onds before the pitching moment takes full effect.
The same applies when you close the throttle (or
switch off the electric motor), but this time in reverse.
In the next section you will see how to adjust the
times for „running up“ (,0.00 sec') and „running
down“ (#0.00 sec_) for the input.
To correct the power moment we wish to add and
subtract the THROTTLE input slowly relative to the
ELEVATOR+ mixer. At the same time the application
of up- or down-elevator is slowed due to the set
SLOW delay, and this allows you to adjust the re-
sponse speed of the THROTTLE input to
ELEVATOR+ exactly to match the model’s behaviour.

6.2 Transmitter control options vary-
ing with flight mode
This is how it used to work:
If you moved to „Menu 1: Adjustments“ and select the
CONTROLS point, the top line of the screen always
displayed the name of the current flight mode.
This is how it works now:
The name of the flight mode is only displayed if the
selected option can be set differently in the various
flight modes.
If the setting applies to all flight modes (SLOW, trim
travel, trim method, AUTO-TRIM) then the top line is
left blank. This gives you a visual reminder that the
settings apply to all modes.
6.3 Control switch status
displayed on the screen
This is how it used to work:
When adjusting the switching threshold you could
previously only see the % value on the screen. You
could only check where the switching point lay with
reference to the transmitter control travel if the control
switch was also assigned to a function.
This is how it works now:
In „Menu 2: Assigning SWITCHES“ an asterisk („*“)
appears next to the control’s code letter if the associ-
ated control is in the „ON“ range.

The same applies if you define the switch as a 2-
position switch.
