Program description - Wing mixers
control function input 1 (throttle/brake stick) on the
»Mix-only channel« menu, which is available as
standard on the
mc-20 HoTT transmitter only,
see page 216, and use it for another purpose
with the help of a “free mixer”, see page 205. On
the mc-16 HoTT transmitter this option can be
unlocked as an extra-cost option.
• If “2AIL” is set in the »Model type« menu, page
104, then flight-phase dependent flap functio-
nality can be achieved with appropriate offset set-
tings for input 5 in the »Control adjust« menu,
page 160, or alternatively can be achieved by
setting appropriate values in the “Offset” column
for Input 5 in the »Control adjust« menu, see
page 118. However, in the interests of clarity you
should always make use of only one of the two fa-
cilities.
• For almost any menu option, you have the option
of checking your settings by switching to the ser-
vo display screen, which is accessed with a simul-
taneous tap on the  selection keys of the left
four-way button.
Caution:
With aileron actuation the bars of the »Servo dis-
play« move in the same manner and in the oppo-
site manner with camber changing flap actuation.
• Note that if two flap servos have been selected,
any transmitter control assigned to input 7 will be
decoupled in the software in order to avoid errors
in operating the flaps. The same applies to input
10 if you select “2/4AIL 4FL” on the
mc-16 HoTT
transmitter with twelve channels unlocked, as well
as the standard twelve-channel mc-20 HoTT
transmitter.
• A range of options are available for positioning
flaps. You can …
a) … simply accept one position per flight phase,
by setting only the corresponding trim values.
b) … vary the flaps positioned by a) with a trans-

All options can then also be programmed specific to a
flight phase.
Comments:
• In the »Model type« menu, see page 104, the
airbrake mixer control can be re-programmed from
control input 1 to 7 or 8 on the standard eight-
channel
mc-16 HoTT transmitter, and from
1 to 7, 8 or 9 on the mc-16 HoTT transmitter
with twelve channels unlocked and the standard
twelve-channel mc-20 HoTT transmitter. In all
three variants it is also possible to define the asso-
ciated Offset point.
• Braking with raised ailerons and, if present, low-
ered flaps (crow system) can be implemented by
making appropriate settings on the “Crow” line of
the “Brake settings” sub-menu.
• If you would like to alternate between the C1 stick
controlling an electric drive system and a butterfly
system, then you can use the options in the “Mo-
tor” column on the »Phase settings« menu – see
page 152 or refer to the example on page 291.
• You can also use the opportunity to set switch
times for a “soft” transition from flight phase to
flight phase on the »Phase settings« menu, see
page 152.
• If your model features multiple wing flaps and a
“crow / butterfly system” (see below), but without
additional airbrakes, then you can separate out-
put 1 (usually freed up by the above system) from
