 TIP:
When you have entered the mechanical values relating
to the swashplate as parameters for the
Rotor head
mixer, the next step is to carry out a careful calibration
of the rotor head servos in Menu K
Servo / Cali-
brate
( Î 16.1.2.). This is the only method of ensuring
accurate swashplate control. The direction of rotation of
the servos can be checked by applying collective pitch
commands. If any servo rotates in the wrong direction,
that servo must be reversed (
REV.). For the servo cali-
bration process you may find it helpful to disconnect
the pushrods between swashplate and rotor head, so
that you can set up the maximum travels (P1, P5).
The control travel settings for roll, pitch-axis and collec-
tive pitch can now be entered in Menu H
Control
(Î 14.1.6. und 14.1.10.).
 TIP: Helicopter with Heim mechanics
If you wish to fly a helicopter with HEIM mechanics,
please use this procedure:
1. Select
HELIccpm as template for the new model
2. Assign a vacant servo channel to
Pitch-axis
3. In the
Rotor head mixer set the geometry to 90°.
This ensures that the servos
HEAD le and
HEAD ri are controlled only by the transmitter
controls for roll and collective pitch
4. The servo
Head f/r is not required. This channel
should be left vacant at the receiver.
16. Main menu Servo K
What can be done in the main menu
Servo?
Calibrate
Here you can alter the direction of rotation of the ser-
vos, set the servo centre, end-points and limits.
Assignment
This menu shows you the sequence of channels and
servo outputs. Some channels can be assigned a differ-
ent control function. The servo signal format and num-
ber of calibration points can be altered for all servos.
Monitor
This menu displays the travels of all servos by means of
bar graphs and - optionally - a numerical display show-
ing % values.
Test run
You can simulate the movement of a transmitter con-
trol. The associated servos then run constantly from one
end-point to the other, at variable speed. This function
is very helpful for range-checking.
16.1. Sub-menu Calibrate
The sub-menu
Calibrate lists all channels 1 - 7 with
their names. When you select a channel / servo, the fol-
lowing display appears (example: SERVO 1 / aileron):
In this menu you can change the following:
- the direction of servo rotation
REV.
- the servo centre
P3
- the servo end-points
P1 and P5
- and - if necessary - the intermediate servo travel
points:
P2 and P4
All changes to the parameters REV. and the servo cali-
bration points
P1 ... P5 are immediately reflected in the
graph, providing a clear, easily understood means of
checking the settings.
