What is a mixer?
Basic functionality
With many models, a mix of the model’s functions
is often desirable, i. e. coupling aileron to rudder or
coupling two servos together, in cases where rudder
control surfaces with the same functionality are to be
controlled together using a single servo. In all cases,
the signal flow at the “output” of the control function
on the transmitter control-side “branches” – , this also
means: “downstream” of transmitter control options
such as e. g. »Dual Rate / Expo«, »Control adjust«,
»Channel 1 curve« etc. – in order for the signal to
have its predefined effect on the “input” of another
control channel and thus on another receiver output.

The mc-16 HoTT and mc-20 HoTT transmitter
software contains a large number of pre-programmed
coupling functions as standard, which are designed
to mix together two (or more) control channels. Ac-
cordingly, the mixer named in the example just above
can be activated in the “Tail type” line of the »Model
type« menu by selecting “V-tail”, see page 104.
In addition, for each model memory in the fixed-wing
and helicopter programs, the software makes avail-
able a total of eight freely programmable linear mix-
ers, four freely programmable curve mixers and four
dual mixers; these are available as standard on the
mc-20 HoTT only, but can also be unlocked on the
mc-16 HoTT transmitter as an extra-cost option.
Also be sure to read the general remarks about “free
mixers” in this manual, beginning on page 204.
