Receiv
er
Interchanging receiver outputs with PCM20 and
SPCM20 receivers
The receiver assignment stated below should be
used for both tail types in order to avoid servos 9 and
10 running jerkily. Carry out the following steps in the
»
Receiver output swap « menu:
• assign servo 9 to output 1, and,
• assign servo 10 to output 8.
Moreover, if you …
• … assign servo 1 to output 9, then receiver output
9 is available for other purposes, perhaps for air-
brakes, or for throttle using the throttle / airbrake
stick, and
• … assign servo 8 to output 10, then a servo con-
nected to output 10, if present, can be operated by
a transmitter control assigned to input 8 (»
Trans-
mitter control adjust « menu), typically for cont-
rolling an auxiliary function.
Servos connected to these two outputs (9 + 10) do
run smoothly provided that they are not affected by
mixers.
The » Receiver output swap « menu (page 153)
should therefore be programmed as follows:

Tip:
You should also select this “PCM sequence” for a six-
fl ap wing if you are using a PPM receiver with only
eight or nine servo sockets.
Important notes:
• If you re-assign the receiver outputs, please note
that any subsequent changes, such as servo tra-
vel adjustment, Dual Rates / Expo, mixers etc.,
must still refer to the basic receiver sequence.
• If you swap over the receiver outputs, please note
that the Fail-Safe programming (“hold” or “pos.”) in
SPCM20 and APCM24 mode always relates to the
default receiver socket numbers; in PCM20 mode,
battery fail-safe always affects receiver output 1.
How are the pairs of ailerons and fl aps cont-
rolled?
1. Both pairs of fl aps are controlled with the aile-
ron function using the aileron stick
• By default, the aileron stick only controls the
two aileron servos 2 + 5. Values other than
zero for the fl aps FL and (if present) FL2 can
be entered individually in the “Multi-fl ap menu”
of the »
Wing mixers « menu.
2. The ailerons are controlled by the fl ap function
using input 6 (e. g. using the INC / DEC buttons
CTRL 5 or 6)
• By default, a transmitter control which is as-
signed to “Input 6” in the » Control adjust «
menu controls the flaps and (if present) FL2
with 100% travel. Values other than zero for
the ailerons, and – if wished – reduced travels
for the flaps, can be entered individually in the
“Multi-flap menu” of the »
Wing mixers « menu.
• If you choose “2 AIL 2 FL” in the “Ailerons /
fl aps” line of the » Model type « menu, a trans-
mitter control assigned to “Input 7” is de-cou-
pled in the software in order to avoid control er-
