This idle path ensures that all brake settings remain 
at "neutral", even with minor deviations from the 
limit of the brake fl ap control. At the same time, 
the effective control path is automatically spread to 
100 %.
For this reason, in the next step it must be ensured 
that the infl uence of the C1 joystick on the motor can 
be infl uenced. For this purpose, switch to the menu 
»Phase settings« 
(page 142)
... and assign a meaningful name, such as "Normal", 
from the list for "Phase 1" after activation of the 
selection fi eld in the "Name" column. The asterisk 
in the second column indicates which phase is 
currently active. As long as no phase switch has 
been assigned, this is always Phase 1. "Phase 2" 
can be given, appropriate to the example, the name 
«Landing».
In the "Ph.Tim" column you can assign a so-called 
fl ight phase timer for the measurement of the motor 
running time and/or the gliding times as necessary 
for each phase. You could, for example, assign one 
of the "Timers 1 … 3" to the "Normal" fl ight phase in 
order to measure the total motor runtime via the C1 
joystick:
»Model type«
(beginning page 94)
Here you fi rst specify in the "motor" line whether the 
throttle minimum position (= Motor "OFF" position) 
should be at the "front" or "rear" - as already 
discussed: In the following programming example, 
"Motor OFF" and "Brake OFF" are combined at "front":

Note:
With the selection of "Throttle min front/rear" the 
trimming will then only have an effect in the "idle" 
direction of the motor and is not the same as with the 
"none" entry, having the same effect at every position 
of the C1 joystick. Since the C1 trimming is not 
normally used with electric drives, however, this has 
no further relevance.
You adjust the "according to your model, in this case 
"normal".
In the "Aileron/fl aps" line you enter the correct 
number of aileron and fl ap servos – in this example 
"2 AIL".
In the last line you leave the standard entries for the 
selection of "Brake retracted = front". On the other 
hand, if the preference is for "Brake retracted = rear", 
select the "Brake offset" line and defi ne the offset 
point – as described on page 95 – as "rear". In the 
process, if the offset point is not placed completely 
at the end of the control travel, the remainder of the 
travel is "idle" up to this limit.

Example 4
Before we discuss the programming of this fourth 
example or turn the to the expansion of the previously 
described basic programming, a few words should be 
said about the position of the throttle/brake joystick 
with "Motor OFF" or "Brake OFF". Normally the C1 
control joystick is moved forward for the throttle 
control and backward for the extension of the brake. 
However, if for this type of "traditional" assignment, 
for example, a switchover of the brake system is to 
take place for the "Motor OFF" condition (joystick 
"back") then a switchover to "full brake" would take 
place immediately after the pre-set switchover time 
specifi ed in the »Phase settings« menu, and the 
opposite will take place when "brakes retracted" is 
switched over to propulsion causing the motor to 
switch over to "full power" within this time range …
A "glider pilot" can make the best of this 
"Emergency" – normally with "brake retracted = 
front" – by switching to motor "ON" only if necessary 
so that power decreases, if applicable (and hopefully 
not forgetting to push the C1 joystick "forward" again 
when switching back). A typical "motor pilot", on the 
other hand, operates in the opposite manner, only 
switching to the brake if necessary, etc... You can 
also combine the "Zero point" of both systems to 
avoid confusion, whereby a "glider pilot" would tend 
prefer the "front" and a "motor pilot", on the other 
hand", would likely prefer the "rear". 
Whichever the case may be, the 
mc-20
 HoTT 
transmitter permits both variants. In the following text, 
however, the combination of the two "OFF" positions 
to "front" is assumed. However, if you have a different 
preference, it is not a problem: The only difference 
from the described version lies in the logical selection 
of "Throttle min rear/front" and, if applicable, of a 
corresponding brake offset in the menu …
