Control adjust

Basic procedure for transmitter control and switch assignment

This option is available as standard on
both transmitter types.

Use the selection keys on the left or right
four-way button to scroll to the »Control

adjust« option in the multi-function menu:

Servo adjustment

Dual Rate / Expo

Stick mode

Channel 1 curve

Switch display

Control adjust

Open this menu option with a tap on the center

SET

key of the four-way button pad. On the standard
eight-channel

mc-16

HoTT transmitter this looks as

follows:

On the

mc-20

HoTT transmitter, this looks as follows:

Note:
To save space the remaining screen-shots in this sec-
tion are based on the display of the standard eight-
channel

mc-16

HoTT transmitter. The pictures also

apply in similar manner to the

mc-16

HoTT trans-

mitter with twelve channels unlocked, and the stand-
ard twelve-channel

mc-20

HoTT transmitter, since

the only difference between the transmitter displays
is the lines “In8” to “In11” located between “Gyro” and
“Lim.”.

Although the basic hardware features of the

mc-16

HoTT and

mc-20

HoTT transmitters are the same,

i. e. two dual-axis sticks for control functions 1 to 4
and the associated trim levers, the standard sup-
plementary controls fitted to the two transmitters are
different.
•

HoTT

• two 3-way switches (SW 5/6 & 11/12)
• two proportional sliders on the middle console,

designated Sl 1 & 2 in the menu

• two side-mounted “rotary sliders”, designated

Lv1 and 2 in the menu

•

mc-20

HoTT

•  three 3-way switches (SW 2/3, 5/6 & 11/12)
•  five 2-way switches (SW 4, 7, 9, 13 & 15)
•  two self-restoring 2-way switches (SW 8 & 14)
•  two unlockable 2-way switches (SW 1 & 10)
•  two push-buttons on the back-side of the trans-

mitter (SW 16 & 17 bzw. 18 & 19)

• two switch-keys (Gb5 & Gb6)
• two proportional sliders on the middle console,

designated Sl 1 & 2 in the menu

• two side-mounted “rotary sliders”, designated

Lv1 and 2 in the menu

In contrast to the two sticks which, even for a newly
initialized “Helicopter” model type will automatically
use the servos attached to receiver outputs 1 … 4
and 6, the aforementioned “other” operating ele-

ments – except for the standard assignment of servo 6
to the right-side proportional slider, designated in this
menu as Lv2 (throttle limiter) – are initially inactive.
One of the effects of this is that (as already men-
tioned on page 77) with a factory-fresh system – as
with a newly initialized model memory for a “Helicop-
ter” model type following its “binding” to the intended
receiver – only those servos connected to receiver
outputs 1 … 4 and – depending on the position of
the throttle limiter – servo 6 can be moved by the two
sticks. Any servos connected to plug-in locations 5,
7 and 8 or 5, 7 through 12, on the other hand, will
simply remain at their center positions.
While this may appear a bit awkward at first glance
… this is the only way to ensure a completely free
selection from among “additional” operating elements
while, at the same time, not requiring the “deactiva-
tion” of unused operating elements. This is because
the only way to ensure an unused operating ele-
ment can have no effect on the model, even if
operated by accident, is to make it inactive, i. e.
not assigned to any function.
All of the aforementioned operating elements can
be freely assigned in this »Control adjust« menu to
any function input, see page 66, just to accommo-
date personal requirements. Equally, this also means
that each of these operating elements can also be
assigned to multiple functions at the same time, as
needed. For example: the exact same toggle switch
assigned to an input in this menu can, at the same
time, also have an assignment in the »Timers (gen-
eral)« menu as an “On/Off” switch, etc.
Furthermore, all inputs can be selectively set to
global or flight-phase specific operation if they have
been defined for flight-phases in the »Phase set-
tings« menu, page 156, and »Phase assignment«
menu, page 158. The names assigned to given flight
phases then appear in the second-from-the-bottom
display line, e. g. «Normal».
