15.7.4. Parameter: Zero point and
Collective Pitch display
Adjust. range
-100% ... 0 ... +100%
Under Zero point you can set the starting point for
the static tail rotor compensation mixer. From this col-
lective pitch angle in the direction of “climb” the collec-
tive pitch Æ tail rotor mixer is active using the value set
under
Coll.+. In the opposite direction (descent) the
mixer works with the value set under
Coll.- (Î
15.7.1.).
Procedure:
1. Move the collective pitch stick to the 0° pitch posi-
tion, using a rotor blade pitch gauge if possible.
Note that you must have set up the collective pitch
curve previously.
2. The value for
Coll. (last line) cannot be altered; it
just shows the current collective pitch stick posi-
tion, and is designed to help you when entering
this setting. Set this value in the parameter
Zero
Point
.
15.8. Mixer: Rotor head
(electronic swashplate mixer / CCPM)
for model helicopters only
The ROYALevo7 features a universal swashplate mixer
(CCPM) which caters for all swashplate types with three
linkage points / servos.
Two parameters are required to set up the mixer:
Geometry, Rotation
Note:
The main menu
Mixer is a dynamic menu; it only dis-
plays those mixers which are used in the current model.
The
Rotor head mixer only appears if you have in-
voked the model template
HELIccpm.
To ensure that the swashplate moves exactly as you
wish it to, the swashplate servos must be connected to
the receiver in the correct sequence. The channel as-
signment varies according to the servo configuration
Servo Config. you have chosen (Î 18.6.). You can
view this at any time in the Servo / Assignment menu
(Î 16.2.):

15.8.1. Parameter:
Geometry
Adjust. range
90 ... 150q / -91 ... -150q
Default 120q
The Geometry parameter defines the angle between
the swashplate servo
Head f/r and the servos Head
le
and Head ri which are arranged symmetrically to
it.
Note
The angle must be entered with a negative prefix “ - “ if
the servo
Head f/r is at the front, as seen from the
tail (example 2).

3-point 120q swashplate

Rotation
+0q
Example 2:
4-point 90q swashplate
Geometry
-90q
Rotation

15.8.2. Parameter:
Rotation
Adjust. range
Range -100° ...0° ... 100q
Default 0q
The Rotation parameter (also sometimes termed vir-
tual swashplate rotation) is required if:
x the swashplate in the model is mounted in such a
way that the
Head f/r servo does not coincide
with the flight axis;
x the model tends to roll when, for example, a pitch-
axis command is applied.
