Program description - Tx. output swap
This option is available as standard on the
mc-20 HoTT transmitter only.
Use the selection keys of the left or right
four-way button to scroll to the »Tx. out-
put swap« menu option in the Multi-function menu:

Fail-safe adjust

Open this menu option with a tap on the center SET
key of the right four-way button:
To ensure that receiver channel assignment is as flex-
ible as possible, the software of the
mc-20 HoTT
transmitter includes the facility to swap over any of
transmitter outputs 1 to maximum 12 as a standard
feature. On the mc-16 HoTT transmitter this option
can be unlocked as an extra-cost option.
Programming procedure
This option lets you distribute the transmitter’s 8 or
12 “control channels” to any of the transmitter outputs
1 … 8 or 12. If you do, you must remember that the
»Servo display« screen – accessible from almost any
menu option by simultaneously tapping the  and 
keys on the left four-way button – refers exclusively to
the “control channels” as preset by the receiver sock-
et assignment: it therefore does NOT take any output
swaps into account.

to be changed then briefly tap the center SET key of
the right four-way button. You can now use the right
selection keys to assign your selected (control) chan-
nel to the desired output, confirming this with the SET

… or, by tapping the  or  selection keys on the
right four-way button at the same time (CLEAR), you
can restore the original assignment.
Any subsequent changes, such as servo travel
adjustments, Dual Rate / Expo, mixers etc., must
always be performed in accordance with the origi-
nal receiver socket assignment!
Example:
In the helicopter program of the
mc-16 HoTT and
mc-20 HoTT transmitters, the outputs for a collec-
tive pitch servo and the throttle servo are swapped
around, compared to some older GRAUPNER/JR
mc units. The throttle servo now occupies transmit-
ter output “6” and the collective pitch servo output “1”.
Perhaps, however, you wish to retain the previous
configuration? In this case, you will swap over chan-
nels 1 and 6 as appropriate, so that (control) channel
6 is located on output 1 and vice versa – as shown
above:
Note:
“Channel Mapping” (channel assignment) is the
receiver-side channel correlation function integrated
into the
mc-16 HoTT and mc-20 HoTT trans-
mitter’s telemetry menu. With channel mapping, the
transmitter’s control channels (12 maximum) can be
freely distributed to multiple receivers or receiver out-
puts having the same control function, for example to
operate two servo controls per aileron surface instead
of just being able to control one servo, etc. To keep
controls manageable, however, we strongly recom-
mend using only one of the options at a time.
