mode once again. Once in the
setup mode, scroll though the
various setup screens until the
display shows:
The first screen shows
current values for the activity
and torque of the aileron servo
with an underline under the
present setting of activity. A
typical screen might show:
Turn the encoder knob to
set the activity level to the
desired value for the particular
aircraft. Any value between 0
and 12 may be chosen. In this
example, the value of 4 will be
selected.
Once activity is set to the
desired value, press and release
the knob to confirm and enter
the selected value into storage.
The underline (cursor) will now
move to the torque setting:
In a manner similar to
activity, use the encoder knob to
select the desired value of pitch
servo torque. This value should
be between 75 and 250. A
default value is set at the factory
but may need to be modified to
suit a particular aircraft. The
value chosen should be
sufficient to fly the aircraft, but
not so much that it is difficult to
override the autopilot if
necessary.
Having selected the desired
torque level, again press and
release the encoder knob to
confirm and enter the selected
torque value into storage. The
next screen will show:
Use the encoder knob to
select the minimum airspeed at
which the autopilot will fly the
aircraft. This speed should be a
safe margin above a stall. Press
the knob to enter the minimum
airspeed into storage.
The final screen in the
setup procedure is the
STATIC
LAG
setup screen. This setting
should only be changed if
autopilot tends to oscillate in
pitch during altitude hold, due
to lag in the static system. The
display will show:
Rotating the encoder knob will
change the number as in
previous setup screens. Having
selected the desired value, press
and release the encoder knob to
enter the value into memory.
This concludes the
Digiflight 200 and 200VS
setup.
