on the "Control adjust" menu. However, you can assign
a transmitter control or switch to this input at any time
– also in a fl ight phase-dependent way – thus enabling
different fl ap settings within a fl ight phase; see also
example 2 on page 260.
EL  FL
To provide support for the elevator for tights turns
and aerobatics, this mixer can be used to make the
fl ap function follow controls sent to the elevator. The
mixer direction chosen must ensure that the fl aps are
defl ected downwards when the elevator is oriented
upwards and vice versa for a downward-oriented
elevator – i.e. in opposite directions.
For each fl ap pair, you can defi ne either a symmetrical
or an asymmetric effect. Position the transmitter control
accordingly – either centrally or to the relevant side.
Values in the range -150% to +150% are possible:

If you tap the  or  keys on the right touch
pad (CLEAR) at the same time, this will reset values
changed in the active (highlighted) fi eld back to the
default value (see screen images).
The "usual" values for this mixer are in the low two-digit
range.
Important general notice:
(Elevator  fl aps)
Do not let control surfaces and servos strike their
mechanical end-stops when large defl ections
are set! This is especially relevant in relation to
the functions "AI", "FL" and possibly
"FL2". Use the "- lim +" option (travel limit)
available on the "Servo adjustments" menu
(page 90), as required.
Notes:
• The "Brake settings" menu is switched "off" if you
entered "Motor on C1 forward / back" on the "Model
type" menu (see page 82), and entered "Yes" for the
0% currently active fl ight phase in the "Motor" column of
0%

Note:
On the "Model type" menu (see page 82), you should
also defi ne the offset, i. e. the direction of operation.
The offset should be set to about +90% of stick travel
(if the C1 stick is used, this is generally located at the
forward position of the stick). To extend the fl aps, the
stick must therefore be moved back towards the pilot.
The remaining joystick travel of around 10% then has no
effect, although it is not "lost", since the control travel is
automatically expanded back to 100%.
Use the select fi elds for the AILE, FLAP and – if present
– FL2 columns to defi ne the extent and direction to
which the corresponding pairs of fl aps are to follow
when the airbrake control (control function 1, 7, 8 or
9) is operated. If the model does not feature separate
airbrakes, leave the corresponding receiver output free
or use the "MIX-only channel" menu to set this to "MIX-
only", to be able to use it elsewhere.
Values in the range -150% to +150% are possible.
If you tap the  or  keys on the right touch
pad (CLEAR) at the same time, this will reset values
changed in the active (highlighted) fi eld back to the
default value (see screen image).
