(The display varies according to the information you
have entered in the “Motor at Ch 1” and “Ail / Flap” lines
in the “
Basic 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 56). For
example, if your model is not fi tted with camber-chang-
ing fl aps, and you have not entered any fl ap servos in
the “
Basic settings ” menu, the software automatically
suppresses all the fl ap mixers, as are the “Brake
¼
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 fl ows 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 sup-
plied “ready-made” in the software, and just has to be
activated in the “tail” line of the “
Basic settings ” menu in
the form of “V-tail”.
The software also includes three freely programmable
linear mixers in the fi xed-wing and helicopter programs,
all of which can be used in each model memory.
