GRAUPNER mx-20 Hott, Programming Manual

Page: 146 / 296

146 Detail program description - Control adjust
" MIX-only channel " (see page 193) and use it for
another purpose with the help of a "free mixer" (see
page 190).
If you set "2AIL" on the "
• Model type " menu (page
82), then the fl ight phase-dependent fl ap functionality
can be achieved by making appropriate offset
settings for input 5 on the "
Control adjust " menu
(page 96).
For almost any menu option, you have the option
•
of checking your settings by switching to the servo
display screen, which is accessed by simultaneously
tapping the arrow keys

on the left touch pad.
Caution:
The vertical lines on the " Servo display " move in
the same direction for ailerons and in the opposite
direction for fl aps.
Note that if two fl ap 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 fl aps. The same applies to input 10 and
the selection "2AIL 4FL".
A range of options are available for positioning fl aps.
•
You can …
a) … simply accept one position per fl ight phase, by
setting only the corresponding trim values.
b) … vary the fl aps positioned as at a) by using any
transmitter control, assigned to "Input 6" on the
"
Control adjust " menu (page 96) – possibly also
made fl ight phase-dependent by selecting "PH" in
the "Type" column. Preferably, this should be one
of the CTRL 6 … 8 proportional rotary controls.
The selected transmitter control directly controls
the two fl ap servos located on receiver outputs 6
and 7 and, as required, also the two FL2 servos
then the fl ight phase name, e. g. "Normal", will appear on
the lower edge of the display:
Aile.diff.
Brake settings
0%
AI 0%
WING MIXERS
EL AI 0% 0%

All options can then also be programmed specifi c to a
fl ight phase.
Comments:
Using the menu " • Model type " (page 82), control
of the airbrake mixers can be reprogrammed from
control input 1 to 7 or 8 to 9, and the associated
offset point can also be set.
If you wish to set up a "butterfl y" system, with the
•
ailerons raised and the fl aps (if present) lowered, this
is achieved by entering the appropriate settings on
the "Butterfl y" line on the "Brake settings" sub-menu.
If you would like to alternate between the C1 stick
•
controlling an electric drive system and a butterfl y
system, then you can use the options in the "Motor"
column on the "
Phase settings " menu – see the
example on page 248.
You can also use the opportunity to set switch times
•
for a "soft" transition from fl ight phase to fl ight phase
on the "
Phase settings " menu (see page 128).
If your model features multiple wing fl aps and a •
"crow / butterfl y system" (see below), but without
additional airbrakes, then you can separate output
1 (usually freed up by the above system) from
control function input 1 (throttle/brake stick) on the

… which means that the only settings listed are the
ones that can actually be confi gured. This not only
makes the menu more compact but also avoids potential
programming errors.
