Rotor Head (Swashplate Mixer) - Multiplex ROYALpro 7 Manual De Instrucciones

ROYAL
The Collective pitch value ( Collect. / last line) can-
not be changed, as it simply shows the current posi-
tion of the collective pitch stick, and serves as an aid
when setting-up. This value is set in the Zero point
parameter.
d. Differential yaw (rudder) travel
The purpose of the Yaw (rudder) differential para-
meter ( Rudd.Diff. ) is to reduce the tail rotor travel in
one direction. This is necessary if the model behaves
differently when yawing (yaw commands) to left and
right (angular velocity). Since the tail rotor has to
counteract the torque generated by the main rotor,
"Yaw" is usually weaker when the model is required to
turn against the direction of the main rotor.
A separate value can be set for each flight phase.

Rotor head (swashplate mixer)

16.2.4.
pro
The ROYAL features a universal swashplate mixer
(CCPM) which can be used to control all types of
swashplate fitted with three or four linkage points /
servos.
Three parameters are required to set up the mixer.
Geometry , Rotation , Lever +/- :
Note:
The main menu Mixer is a dynamic menu, i.e. it only
displays those mixers which are used for the current
model. The mixer Rotor head only appears if you
have selected the model template HELIccpm .
To ensure that the swashplate moves in the required
manner, the swashplate servos must be connected to
the receiver in the correct sequence. The channel as-
signment varies according to the selected servo con-
figuration and can be viewed at any time in the menu

the swashplate servo HEAD f/ b and the two symmet-
rically positioned servos HEAD le and HEAD ri .

Note:
The angle must be entered with a negative prefix " - "
if the servo HEAD f/b is at the front when seen from
the tail, looking forward (Example 2).

The Rotation parameter (also known as virtual swash-
plate rotation) must be used if:
a. the swashplate is positioned physically in the model
in such a way that the servo HEAD f/b is not lo-
cated on the centreline,
b. the model (typically) tends to roll when a pitch-axis
(elevator) command is given.
