Normally a non-linear control function, if applicable, is
used for the aileron (channel 2), elevator (channel 3)
and rudder (channel 4). These channel defaults also
correspond to the factory settings.
BUT CAUTION:
This assignment only applies when, on the
transmitter side, neither “2HRSv3+8” is speci-
fied in the “Tail type” line nor is “2AIL” or “2AIL
2FL” specified in the “Aileron/camber flaps” line of the
»Model type« menu, page 126. Otherwise, assign-
ments will have already been made in the transmitter
for control function3 (elevator), which will then be split
between control channels 3 & 8, or control function 2
(aileron), which will then be split between control chan-
nels 2 & 5 for the left and right ailerons. The corre-
sponding control channels (INPUT CH) in the receiver
would in both cases be channels 03 & 08 or 02 & 05.
Therefore if, for example, “2AIL” has been specified
on the transmitter side and the intent here is to utilize
the RX CURVE option instead of the
mc-16 HoTT
or mc-20 HoTT transmitter’s individually adjustable
»Dual Rate / Expo« menu, see page 126 or 130,
then two curves must be set. Otherwise, the left and
right ailerons have different control characteristics:

CURVE1 CH : 02
TYPE : A
CURVE2 CH : 05
TYPE : B
CURVE3 CH : 04
With the RX CURVE function you can manage the con-
trol characteristics for up to three servos:
• CURVE 1, 2 or 3 CH
Select the desired control channel (INPUT CH) of
the first servo.
The following setting in TYPE only pertains to the
channel selected here.
TYPE
Select the servo curve:
A: EXPO = -100 % and DUAL RATE = 125 %
The servo reacts strongly to movements of the stick
around the neutral position. As the rudder throw in-
creases, the curve becomes flatter.
B: Linear setting.
The servo follows the stick movement linearly.
C: EXPO = +100 % and DUAL RATE = 70 %
The servo reacts weakly to the stick movements
around the neutral position. As the rudder throw in-
creases, the curve becomes steeper.
Note:
The control characteristics programmed here
also affect the mapped receiver outputs.

5CH FUNCTION:SERVO
Some receivers have a specific servo connection which
has been made switchable rather than an independent
telemetry connection. Thus, for example, on the GR-12
receiver included with the mc-16 HoTT and mc-
20 sets, No. 33112, servo connector 5 has an extra
“T” mark and can be alternatively connected …

Sensor
OR
No.S1012
L
… not only via an No. 7168.6S adapter cable to up-
grade the receiver but also connected to a tele metry
sensor.
However, in order for the receiver to correctly recog nize
the given connected device correctly, servo connection
5 (in this case) MUST be appropriately set for either
“SERVO” or “SENSOR”.
