The advanced developments incorporated into the
transmitter as well as those now in helicopter models
and their components like gyros, speed regulators, rotor
blades, etc. make it possible to master a helicopter even
in 3D acrobatic fl ight. On the other hand, a beginner
needs only a few settings to get started with hovered
fl ight training and then can take advantage of mc-32
HoTT features, step-by-step, with increasing expertise.
The mc-32 HoTT program can operate all
conventional helicopters having 1 … 4 servos for pitch
control.
Six fl ight phases plus autorotation are available within
a model memory, see menus "Control adjust", "Phase
settings" and "Phase assignment".
As with winged aircraft, here too, in addition to the basic
screen's standard timers there are additional timers
as well as a lap counter with fl ight-phase-dependent
stopwatch functionality which are available for selection
(menus "Timers (general)" and "Fl. phase timers").
Except for pitch/throttle trimming, digital trimming can be
stored as "global" for all fl ight phases or as "fl ight phase
specifi c". C1 trim permits easy location of an idle setting.
The control assignments of inputs 5... 12 can be made
common to every fl ight phase or separate ("Control
adjust" menu).
A fl ight phase copy function is helpful during fl ight trials
("Copy / Erase" menu).
"Dual Rate" and "Exponential" functions can be coupled
for roll, nick and tail rotor and programmable in two
variations in every fl ight phase.
There are 8 freely assignable linear mixers. There are
also 4 curve mixers that can be programed and these
can also be switched on or off, depending on the fl ight
phase, in the "Mix active/Phase" menu. Beyond this,
there are also 4 dual mixers available.
Available in the "Helicopter mixer" menu are fl ight-
phase-dependent 6-point curves for pitch, throttle and
tail rotor mixer non-linear characteristics as well as two
independent swashplate mixers each for roll and nick.
Independent of this, the control curve of the channel
1 joystick can be defi ned with up to 6 points in every
fl ight phase. The beginner will initially only adapt the
hover fl ight point to the control middle for the non-linear
characteristics.
Pre-programmed mixers in the "Helicopter mixer"
menu:

Channel 1 2. ¼ Throttle (6-point curve)
Channel 1 3. ¼ Tail rotor (6-point curve)
Tail rotor 4. ¼ Throttle
Roll 5. ¼ Throttle
Roll 6. ¼ Tail rotor
Nick 7. ¼ Throttle
Nick 8. ¼ Tail rotor

Swash limiter11.
The "Throttle limit" function (input 12 in the "Control
adjust" menu) allows the motor to be started in any
fl ight phase. Control 6 – the proportional rotation control,
CTRL 6 top left – is assigned to input 12 by default. This
"throttle limiter" establishes – depending on its given
position – the maximum possible carburetor position.
This makes it possible for the motor to be controlled in
the idle range, if necessary even by the proportional
regulator. The throttle curves become effective only
when the proportional regulator is pushed toward the full
throttle direction.
