non-linear fi ve-point collective pitch curve, AR throttle position (-125% ... +125%) and
tail rotor offset (AR), gyro suppression and swashplate rotation.
• • Free mixers Select linear mixer 1 ... 4 or curve mixer 5 or 6 with the rotary control pressed in. Defi ne mixer input (any control
function) in “from / to” column; select “from” and output “to” using associated
SEL function and rotary control. If a
constant control function is required as input, e.g. motor ON / OFF, then select letter “S” in the “from” column (cor-
responds to DUMMY mixer in the mc-20), and assign mixer switch in column 4. Include preceding mixers (symbol
“
”) and / or trim (“Tr”) of stick 1 ... 4, after setting mixer input in the “Type” column. Select corresponding symbol
“ ”, “Tr” or “Tr ” using rotary control. An (optional) switch can be assigned to any mixer.
Setting mixer ratio and direction with linear mixers:
switch to “Setup” column on the screen page with brief press on rotary control. Select ASY or SYM and set mixer
ratio within the range 0 to +/-150% using the rotary control. To set asymmetrical values, select the side of neutral
using the input channel (vertical line on graph), or by operating the switch in the case of the switched channel “S”.
Setting non-linear mixer curves with curve mixers 5 and 6:
three additional reference points can be defi ned between the two end-points “L” (low) and “H” (high). Basic opera-
ting instructions: see »
Channel 1 curve « menu on page 68 / 70.
Shifting the offset point (mixer neutral point):
use the transmitter control to move the bar in the graph to the appropriate position, select STO and press the ro-
tary control briefl y. Press the bottom CLR fi eld to move the offset point back to centre.
Notes:
DUAL RATE may limit the offset range of the vertical line!
Mixers may be suppressed in the »
MIX active / phase « menu!

• • MIX active / phase The mixers 1 ... 6 can be disabled separately for each fl ight phase. In the » Free mixers « menu they are then sup-
pressed separately for each fl ight phase!
108
• • Mix-only channel This function separates the link between transmitter control 1 ... 10 and the associated servo, i.e. the control only
affects the relevant channel as a mixer input. In this case the de-coupled servo is only accessible via a mixer. 108
• • Dual mixer Two mixers designed for coupling two channels in such a way that they work in the same direction and in opposed
directions. Example: camber-changing fl aps (receiver outputs 8 and 9) with aileron function: defi ne dual mix „
8
, 9 “. In the » Control adjust « menu assign a (free) transmitter control, e.g. control 7, to input 8 for the fl ap
function, and in the » Free mixers « menu defi ne the mixer „AIL 9“ to provide an aileron function. If necessa-
ry reverse the direction of rotation in the » Servo adjustment « menu, and set the required aileron differential (0 ...
100%) in the last column “Diff”. Also suitable for other applications, e.g. differential rudder defl ection with a V-tail.
In this case “EL” is defi ned as a same-direction mixer:
EL , and “RU” as an opposed mixer:, RU “, Ple-
ase note that in this case the tail type must be entered as “normal” in the » Model type « menu!
