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 fl ow at the "output" of the control function on
the transmitter control side "branches" – i. e. also "after"
transmitter control options such as e. g. "
Dual Rate /
Expo ", " Control adjust ", " Channel 1 curve ", etc. – in
order for the signal to have its predefi ned effect on
the "input" of a different control channel and thus on a
further receiver output.

The
mx-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. Accordingly, the mixer named in
the example just above can be activated in the "Tail" line
of the
"Model type" menu by selecting "V-tail".
In addition, for each model memory in the fi xed-wing
and heli programs, the software makes available a total
of eight freely programmable linear mixers, four freely
programmable curve mixers and four dual mixers.
Also ensure you read the general remarks on "free
mixers" in this handbook (p. 180).
