(The display varies according to the information you
have entered in the “Motor at Ch 1” and “Ail / Flap” lines
in the “
Base settings ” menu. The selection above shows
the maximum number of options, and equates to the
setting “No (motor)” and “2AIL 2FL”).
The
mx-16
HoTT transmitter’s program contains a se-
ries of pre-programmed coupling functions, and all you
have to do is set the mixer ratios and (optionally) assign
a switch. The number of pre-programmed mixer func-
tions in the mixer list will vary according to the pre-set
“model type” (tail type, number of wing servos, with or
without motor - see the section starting on page 74). For
example, if your model is not fitted with camber-chang-
ing flaps, and you have not entered any flap servos in
the “
Base settings
” menu, the software automatically
suppresses all the flap mixers, as are the “Brake  NN
*“ mixers if you enter “Idle forward” or “Idle back” in the
“Motor at Ch 1” line. This makes the menus clearer and
easier to understand, and also avoids potential program-
ming errors.
What is a mixer?
The basic function
In many models it is often desirable to use a mixer to
couple various control systems, e. g. to link the ailerons
and rudder, or to inter-connect a pair of servos where
two control surfaces are actuated by separate servos. In
all these cases the signal which flows directly from the
“output” of a transmitter stick to the associated servo
is “bled off” at a particular point - this effect can also
be “concealed” in transmitter control options such as
“
D/R Expo
” or “
Transmitter control settings
” - and
the derived signal is then processed in such a way that
it affects the “input” of another control channel, and
therefore eventually another receiver output.

The mx-16 HoTT transmitter software contains a
large number of pre-programmed coupling functions as
standard, designed to mix together two (or more) control
channels. The mixer required in this example is supplied
“ready-made” in the software, and just has to be acti-
vated in the “tail” line of the “
Base settings ” menu in the
form of “V-tail”.
The software also includes three freely programmable
linear mixers in the fixed-wing and helicopter programs,
all of which can be used in each model memory.
