15.6.1. Parameter: Mode
The ROYALevo7 offers 3 different gyro modes:
Control mode
Application:
Normal or heading-hold gyro, featuring gyro gain ad-
justment via a separate control channel. This is the sim-
plest gyro mode.
You can adjust gyro gain manually using the “gyro”
transmitter control (slider E), regardless of the position
of the flight phase switch.
Damping mode
Application:
Standard gyro, featuring gyro gain adjustment via a
separate control channel.
The gain of the gyro is adjusted using the
Damping pa-
rameter. For each flight phase you can set a separate %
value for gyro gain. In this way the gyro can be set up
accurately to suit any flight task or flight phase.
Heading mode
Application:
Modern heading-hold gyro, featuring gyro gain adjust-
ment via a separate control channel.
The gain and mode of operation (damping / heading
hold) of the gyro are adjusted using the
Damping /
Heading
parameter. The gyro gain and mode of opera-
tion can be set separately for each flight phase. In this
way the gyro can be set up accurately to suit any flight
phase.
15.6.2. Parameter:
Heading / Damping
(gyro gain)
In
Control gyro mode:
Gyro gain can only be set manually using the “gyro”
transmitter control
(Î 15.6.1.).
Note: % values for gyro gain entered under
Damping or
Heading have no effect in Control mode.
In
Damping gyro mode:
Adjust. range
OFF (= gyro OFF)
... + 100% (= max. gain)

Separate values can be set for each
flight phase
F
Value can be assigned to a 3D digi-
adjustor
(Î 11.2.2.)
The set value for the Damping parameter (gyro gain)
can be entered separately for each flight phase. The
gyro transmitter control has no influence on the set
values.
In
Heading gyro mode:
Adjust. range
1% ... +100%
 The gyro operates in damping
mode
-1% ... -100%
 The gyro works in heading mode

Separate values can be set for each
flight phase
F
The value can be assigned to a 3D
digi-adjustor
(Î 11.2.2.)
If you set a gain value in the range 0 ... –100% ( Head-
ing
mode), the yaw trim is switched off. Trim changes
affect a separate heading yaw trim memory. This trim
value is applied in all flight phases which work in
Head-
ing
mode, allowing you to carry out minor corrections
(compensating for temperature drift). This trim is dis-
played in status display 1 - 3.
In Damping mode the
Trim parameter (Î 14.1.2.) con-
tinues to display the trim according to flight phase.
At the same time the static tail rotor compensation
mixer
Tail ( Î 15.7.) is switched off.
! Note
If you are using a heading-hold gyro system in Heading
mode, you must check before flying the model that the
gyro is working with the gain you have selected and is
set to the appropriate mode of operation:
1. Activate a flight phase in which gyro gain is set
within the range 0 ... -100% (
Heading).
2. Move the yaw / tail rotor stick to either end-point,
then back to the neutral position (centre).
If the yaw / tail rotor servo immediately moves back to
its starting position, the gyro is operating in damping
mode:
 in this case the direction of rotation of the
Gyro
channel must be reversed! (Î 16.1.)
15.6.3. Parameter: Suppression
Adjust. range
OFF (= no suppression)
... 200% (= max. suppression)
Many gyros reduce their gain automatically when a tail
rotor command is given; without this suppression the
gyro would damp out deliberate control commands. If
you are using a gyro without its own automatic sup-
pression, you should activate this function (but please
read the notes in the operating instructions supplied
with your gyro!).
In model helicopters the suppression is applied when
the pilot operates the “yaw” (tail rotor) stick; with fixed-
wing models the suppression is applied when the pilot
moves the “aileron” stick.
