Typical collective pitch curves for different fl ight pha-
ses:
It can be very useful to adjust each individual re-
ference point independently of the adjacent points
using the rotary control!
Once you have defi ned the collective pitch curve,
switch to the fi rst screen page by pressing
ESC
, and
then select the next line (if appropriate):

In contrast to the »
Channel 1 curve
« menu this dis-
play refers only to the control curve of the throttle ser-
vo, whereas the “Channel 1 curve” applies to all the
servos which are affected by the throttle / collective
pitch stick. Note that the output signal of the “Channel
1 curve” acts as input signal for the throttle curve pro-
grammed at this point: the vertical line in the diagram,
which moves in parallel with the throttle / collective
pitch stick, follows the actual Channel 1 curve.
The throttle curve can also be defi ned using a ma-
ximum of fi ve points – termed “reference points” –
along the full stick travel; different curves can be set
for each fl ight phase.
The reference points are defi ned, adjusted and
erased in the usual way, as explained in the previous
section relating to the collective pitch curve. First de-
fi ne the throttle curve with the three points which are
already set in the software, i.e. the two end-points “L”
and “H” and Point “1” in the centre of the control arc,
then adjust the motor power curve to match the coll-
ective pitch curve:
• The throttle must be fully open at the end-point of
the throttle / collective pitch stick (exception: auto-
rotation; see below).
• The hover point is normally located at the centre
of the control travel, and the throttle setting must
be adjusted in such a way relative to the collecti-
ve pitch curve that the correct system rotational
speed is obtained at this point.
• In the minimum position of the throttle / collecti-
ve pitch stick, the throttle curve should be set up in
such a way that the motor runs at a distinctly hig-
her speed compared to the idle setting, with the
clutch reliably engaged.
In all fl ight phases the motor is started and stop-
ped using the gas limiter (see below).
If you are used to a different radio control system
which uses two separate fl ight phases for this –
“with idle-up” and “without idle-up” – please note
that this complication is now superfl uous, and for
reasons of safety we strongly recommend that you
adopt the new system.
Note:
Increasing system rotational speed below the ho-
ver point is more fl exible and easier to control
using the mc-22s program than using “idle-up” as
employed in previous mc radio control systems.
Ensure that the gas limiter is closed before you start
the motor, i.e. the throttle can only be adjusted within
the idle range using the idle trim. Please be sure to
read the safety notes on page 98 which refer to this. If
the idle is set too high when you switch the transmit-
ter on, you will see and hear a clear warning!

The following three diagrams show typical three-point
throttle curves for different fl ight phases, such as ho-
ver, aerobatics and 3-D fl ying.
Please note that trim values greater than +100% and
less than -100% cannot be displayed on the screen.

Notes on using the “Throttle limit” function:
We strongly recommend that you make use of the
throttle limit function (»
Control adjust
« menu, page
62). When you use this function, the throttle servo is
completely disconnected from the throttle / collecti-
ve pitch stick when the throttle limit slider is at its bot-
tom end-point; the motor idles and only responds to
the Ch1 trim. This feature enables you to start the
motor from within any fl ight phase. Once the motor is
running, slide the throttle limiter to the opposite end-
point, so that full control of the throttle servo is re-
turned to the throttle / collective pitch stick. It is im-
portant that the throttle limiter should not restrict the
throttle servo at its top end-point; you can avoid this
