mitter control assigned to “Input 6” in the »Con-
trol adjust« menu, page 118, and if desired
by also selecting flight-phase dependency “PH”
in the “Type” column.
The selected transmitter control directly con-
trols the two flap servos located on receiver
outputs 6 and 7 and, as required, also the two
FL2 servos connected to outputs 9 and 10 – as-
suming that corresponding flaps have been
specified on the “Aileron/camber flaps” line in
the »Model type« menu. This transmitter con-
trol indirectly controls the flap position of the ai-
lerons via the percentage value entered in the
“AILE” (and “AIL2”) column on the “FLAP” line
of the multi-flap menu.
The two INC/DEC buttons, CTL 5 or 6, are vir-
tually ideal for this type of task, since their posi-
tion is automatically stored. These buttons are
fitted as standard on the
mc-20 HoTT trans-
mitter, but can be fitted to the mc-16 HoTT at
extra cost.
The particular advantage of these two trans-
mitter controls – especially if you select the
“PH” setting – lies in the fact that you can use
one and the same INC/DEC button as flap trim
controls in all the programmed flight phases,
but – in contrast to a position-related propor-
tional control – the trim values are retained even
if you switch models.
However, in order to improve control sensitivi-
ty for flap settings, travel should be reduced to
about 25 % in “Input 6” line of the »Control ad-
just« menu.
c) … alternatively, you can also leave the default
entry of “0 %” in the “AILE” (and “AIL2”) column
on the “FLAP” line of the multi-flap menu, and
use the »Control adjust« menu to assign both
input 6 and input 5 to the same transmitter con-
trol. You can then set the degree to which both
Assigning switches
Wing mixers “AI  RU” and “FL  EL” can be made
optionally on/off switchable by way of a switch or
expanded switch. Accordingly, when the respective
line is selected, the familiar switch symbol (
) will
appear on the lower edge of the screen.
A switch can be assigned as described in the section
entitled “Physical control, switch and control switch
assignments” on page 68.
Switching delays
The delay time or switch time configured on the
»Phase settings« menu, page 152, for the respec-
tive flight phase also affects all wing mixers and thus
avoids abrupt changes to flap configurations when
switching between the flight phases.
Mixer neutral points (Offset)
For all mixers on the “Brake settings” sub-menu, the
“brake offset” to be set on the »Model type« menu is
to be configured to the transmitter control position at
which the airbrakes are retracted.
For this reason you should define which of the inputs
1, 7 or 8 you wish to use as the brake control, and
enter the appropriate offset, in the “Brake offset” line
of the »Model type« menu on the standard eight-
channel
mc-16 HoTT transmitter, corresponding to
your personal preference; see page 105. The same
procedure is used with the mc-16 HoTT transmit-
ter with twelve channels unlocked, and the standard
twelve-channel mc-20 HoTT transmitter, with the
exception that Input 9 is also available as an alterna-
tive. When selecting “input 1”, please note also that
you may need to specify your desired “Throttle min”
position “forward/back” before establishing the offset
point in the “Motor at C1” line.
Note:
If the offset is not set right at the end of the transmit-
ter travel, the rest of the travel is a “dead zone”, i. e.
flap pairs are affected, optionally making this
flight phase-dependent by selecting “PH” in the
“Type” column, with the respective travel adjust-
ment.
Basic programming procedure
1. Select the desired line with the  selection keys
of the left or right four-way button.
Depending on the line selected, the bottom line of
the display will either show the “Next page” (
)
icon or a switch icon.
2. Depending on the line selected, you will either
switch to the next page – on which you carry out
the same procedure as below – or the desired va-
lue field is activated by tapping the center SET key
of the right four-way button.
3. Use the selection keys to set the mixer ratio or de-
gree of differential.
To configure symmetrical mixer values, move the
transmitter control or stick to its center position, so
that the marker frame surrounds both value fields.
To configure asymmetric values, move the trans-
mitter control/stick to the corresponding side.
Negative and positive parameter values are pos-
sible, in order to be able to adjust the respective
function to the direction of servo rotation or flap
orientation.
4. A simultaneous tap on the  or  keys of the
right four-way button (CLEAR) will reset the entry
value in the given active (inverse video) field back
to its default value.
5. Complete the entry with a tap on the center ESC
key of the left four-way button or the center SET
key of the right four-way button.
