In some special cases, such as retracts, the normally
fast transit time of a servo does not look right.
With code 79, the transit time of a servo connected to
any of the channels may be slowed-down from 0.5s to
30s when moving from one end point to the opposite
end point.
After activation of code 79, the desired channel has to
be selected using keys 1 … 9 .
Transit time is slowed down by the INC key, with
steps being very small for short transit times and
larger with longer ones. Below 1.5s the steps are so
small that the display only changes after several
steps. In all some 50 intermediate values are
provided. Pressing the DEC key reduces the transit
time and the CLEAR key cancels the deceleration
completely.
This function is not compatible with retract servos
such as G503 (order N° 3977) and C2003
(order N° 3890).

Control travel resulting from actuating an operating
element on function inputs 6 – 8 is adjusted by code
16.
The range of adjustments amounts to 0 – 150% of the
normal range. Unlike code 12 (servo travel adjust),
these adjustments refer to the operating element
(slider, rotary control or switch) independent of the
latter acting directly on a single servo or via a
complex mixing and coupling function on several
servos.
After calling code 16 and input of the function
concerned via keys 6 … 8 , the adjusted control
range will be indicated with a prefix + or – indicating
the side. For adjustment and display the operating
element concerned has to be moved to the end point
in question. The control range is then adjusted using
the INC and DEC keys, or set to the normal (100%)
via the CLEAR key.

Code 31 permits changing the characteristics of the
servo connected to channel 1 (throttle/spoiler) at
neutral position of the stick without affecting the end
position.
This setting can be used to compensate for non-linear
throttle response, or to intentionally obtain a non-
linear function of the spoilers, for example.
After calling code 31 adjustment of servo travel is
performed using the INC and DEC keys, while
directional changes can be made via the TURN key.
