The next step is to select a name for the model me-
mory you have chosen; the name is entered in the
menu …

Your choice of “ Model name ” is entered virtually in
exactly the same way as the user name, which was
described on the left-hand page under »
Basic set-
tings «.
Once you have entered the model name, you should
again check the basic settings (“
Stick mode ” and
“ Modulation ” in the » Basic settings « menu) you
have already programmed, while you can still change
them for the model memory you have selected.
Under “ Trim steps ” set the increment size for each
“click” of the digital trim levers. In the Heli model type
the Ch1 trim
only affects the throttle servo. The thrott-
le trim has several special features (“motor cut-off
trim” etc.), but as they have already been described in
detail we will not go into them again here; please read
the sections on pages 32 and 62. Since the trims are
digital, the trim values are automatically stored when
you switch model memories.
We now come to the fi rst setting which is specifi c to
helicopters. Move to the menu ...

Under “ Swashplate type ” select the type of linkage
for the swashplate / collective pitch function; in our ex-
ample this is “3Sv(2roll)”.
In the “ Rotor direction ” line we set the direction of
rotation of the main rotor as viewed from above. This
means: clockwise or anti-clockwise – in our example
“right” (clockwise).
Check again that “ Pitch min. ” is set correctly, as it
is adopted from the » Basic settings « menu. Ensu-
re that the “forward” or “back” entry suits your perso-
nal preference.
We can safely ignore “ Expo throttle lim. ” for the mo-
ment.
At this point, if you have not already done so, the ser-
vos should be connected to the receiver in the follo-
wing order:
Please note one important difference in the mx-16s,
mc-19, mc / mx-22 and 22s and mc-24 compared

The Heli program automatically sets the mixer ratios
and mixer directions for the swashplate servos for col-
lective pitch, roll and pitch-axis to +61% in each case.

If the swashplate does not respond correctly to the
stick movements, the fi rst step is to change the mixer
directions from “+” to “–” if necessary. The second re-
course is to reverse the servo directions in the »
Ser-
vo adjustment « menu.
Now move to the menu ...

… where you can set up the travels and directions of
rotation of the individual servos.
The basic aim here should be to keep servo travels
at +/-100% wherever possible, as this maintains best
possible resolution and accuracy. Use “Rev.” if neces-
sary to reverse the direction of rotation of any ser-
vo; do check carefully that the direction you set real-
ly is correct. The tail rotor servo must operate in such
a way that the nose (!) of the helicopter moves in the
same direction as the movement of the tail rotor stick.
