Within one model memory, the 

mx-20 HoTT lets you 

program up to 6 discrete groups of settings for various 
conditions met during the fl ight. These are in addition to 
the auto-rotation fl ight phase that can be set up in the 
"Base setup model" menu. The grouped settings are 
typically termed "fl ight phases" and are programmed in 
the corresponding menus.

When you set up fl ight phases for helicopter models, 
you start with this menu. You assign individual phases 
a name and also assign a period of time for a (soft) 
transition into each phase. Note that – depending on 
your model and your settings – switch times much longer 
than the default 0.1 s have proven useful. You can also 
set up several phases with names and transition times 

Setting up fl ight phases

even if you don't currently have a use for them, since 
the decision as to which of the "occupied" phases you 
activate is made only on the "Phase assignment" menu 
(page 134) when setting "phase switches".
The "Status" column, second from the left, shows which 
one of the phases 1 … 6 has already been assigned to 
a switch, plus the current status of that switch:

–

No switch assigned

+

Phase can be accessed via switch



Indicates the phase currently active

The fi rst line, and thus the fl ight phase with top priority, 
is reserved for auto-rotation fl ight – see the "Base setup 
model" menu. Accordingly, the predefi ned name cannot 
be changed.
Use the arrow keys to move to the line "Pha1". Briefl y 
tap the center 

 key on the right touch pad and use 

the arrow keys on the left or right touch pad to assign 
each of the phases your require – phase 1 to max. 
phase 6 – an appropriate name from the selection list. 
The order in which phases 1 to max. 6 are assigned is 
entirely irrelevant and you can leave gaps as you wish. 
Nonetheless, you should always start with "Phase 1", 

the "Normal phase", which is always active if …

no phase switch is set on the "

• 

Phase assignment" 

menu or if
no phase has been assigned to specifi c combinations 

• 

of switches.

The defi nition of the phase name "Normal" could 
therefore be a useful one to adopt for "Phase 1". 
The names themselves have absolutely no technical 
signifi cance for programming; their only purpose is to 
help you to identify which phase is active at any time 
and are thus displayed in all fl ight phase-dependent 
menus and also on the transmitter's basic display.

In addition to the standard timers on the basic screen 
display, other timers are also available, whose settings 
are confi gured on the "Fl. phase timers" menu 
(page142).

 Clk 1, Clk 2, Clk 3, Lap, Time1, Time2
The fl ight phase timers "Clk 1 … 3" plus "Time1" and 
"Time2" run only in the fl ight phase to which they have 
been assigned in this menu. During other fl ight phases 
they are stopped (and hidden) and the assigned stop/
start switch then has no effect.
The lap counter, once started, continues to run through 
changes of phase, however, although it can be stopped 
during any fl ight phase via the center 

 key on the 

left touch pad.
While you can obviously record lap times using "Lap" 
and a switch (SW), the two timers "Time1" and "Time2" 
have the following meaning:
Time1 Only the times are measured at which the switch 

or control switch assigned in the "Lap timer/
timer" line of the "Fl. phase timers" menu (see
