The collective pitch curve for model helicopters is set up
in the menu H Control / Coll.P. For each flight
phase a separate collective pitch curve can be set up in
the ROYALevo7, each with six curve points P1...P6, so
that the best possible match of collective pitch control
can be obtained for each flight phase. As an aid to set-
ting up, a vertical dotted line appears in the graph of
the curve showing the current position of the collective
pitch stick.
Example 1: Collective pitch curve, flight phase HOVER
A "flatter" collective pitch curve from hover collective /
stick centre to min. collective / descent is intended to
provide finer control at the hover and at touch-down.
Example 2: Collective pitch curve, flight phase CRUISE
Linear, symmetrical collective pitch curve for constant
collective pitch control in climb and descent modes.
Overall higher max. collective pitch values, as generally
a higher system speed is set (throttle curve), so that
higher rates of climb are possible.
For the first time the ROYALevo includes a 6-point col-
lective pitch curve. The advantage, especially for mod-
ern, high-power 3-D helicopters with a broad collective
pitch range (up to 10...12 ), is the ability to set "pla-
teaux" in the "normal" and "inverted" areas, giving fine
control at the hover.
Example:
Note:
It is only ever possible to display the collective pitch
curve for the active flight phase. If you wish to make
changes to a collective pitch curve, ensure that you first
set the desired flight phase.

( 11.2.2.)
The throttle curve for model helicopters is set up in
menu H Control / Throttle. For each flight phase
(F-PH 1-3) a separate 5-point throttle curve can be set, in
order to obtain the best possible matching of motor
power to the collective pitch curve setting for the flight
phase in question. The aim is to achieve a constant sys-
tem rotational speed over the entire range of collective
pitch. The throttle curve can only be fine-tuned accu-
rately when the model is in flight, as it varies according
to many parameters (motor power, motor setting,
power characteristics, collective pitch curve, rotor
blades installed, etc.). If any one parameter is changed,
the throttle curve generally needs to be adjusted anew.
As an aid to setting up, a vertical dotted line appears in
the graph of the curve showing the current position of
the collective pitch stick.
Example 1: Throttle curve, flight phase HOVER
Simple throttle curve for the hover. At negative collective
pitch (= descent) least motor power is required (in our exam-
ple P1 = 35%). At positive collective pitch (= climb) maximum
power is required (in our example P5 = 85%).
Example 2: Throttle curve, flight phase 3D
Symmetrical, V-shaped throttle curve, opens the throt-
tle setting when climbing either upright or inverted.
