• "Gyro Suppression" line

Notice

This option may normally not be used for cur-
rent standard gyro systems. You therefore
need to consult your gyro setting instructions

since otherwise you may make it impossible to fly
your helicopter. Nonetheless, this sub-menu was re-
tained to satisfy all requirements and conventions.

This option can influence the effect of the gyro
sensor (gyroscope) as the tail rotor control stick
is moved, assuming that a gyro system is used in
which the gyro's effect can be set by the transmit-
ter using an additional channel, channel 7 in the

Graupner

remote-control system

The gyro sup-

pression reduces the gyro's effect in a linear man-
ner in proportion to the deflection of the tail rotor
control stick corresponding to the set value. If the
gyro has not been suppressed (at a value of 0%),
the gyro's effect remains independent of the con-
trol stick deflection.
The gyro's effect can however be additionally var-
ied smoothly between a minimum and maximum
using a control assigned in the "Gyro" line in the
"

CTL Set

" menu, for example with one of the pro-

portional dials DVx. More on this subject can be
found in the section "

Gyro/governor

• "Gyro Gain" line

Most of the current gyro systems can be adjust-
ed for a smooth, proportional effect; you can also
choose between two different modes of action by
the transmitter.

If the gyro that you are using also has one of these
options, the alternative offset setting enables both
the normal gyro gain and "heading lock mode" as
well as flying with maximum stabilization in normal,
slow fights within this selected mode, and reduc-
ing the gyro gain in fast roundtrips and aerobatics.
Values up to ±125% are possible, for example:

Based on these phase specific settings (offset) the
gyro gain can also be proportionally varied with a
control assigned in the line "C7" in the sub-menu
"

CTL Set

", as for example the proportional dial

DVx.

Attention

• You therefore need to consult your gyro

setting instructions since otherwise you
may make it impossible to fly your helicop-
ter.

• Note that the offset values entered in this

option as well as in the line "CH 7" of the
sub-menu "

CTL Set

" add up! For the

sake of clarity, make sure to only enter or
change an offset value in one of the two
options.

• "Governor ACT" line

In contrast to speed

controllers

that only regulate

performance like a carburetor,

governors

maintain

a constant speed in the system that they are mon-
itoring by independently regulating the provided
output. Like the cruise control in cars, a governor
controls in case of ice engine helicopter the throt-
tle servo in the same way as the speed controller
of an electric motor helicopter.

Governors there-

fore only require a speed setting and not a classic
throttle curve.

A deviation from the set speed oc-

curs when the required output exceeds the maxi-
mum available output.
To change the current value, touch the desired
button in the "Governor ACR" line. The display
switches from "

OFF

" to "

" and vice versa, for

example:

• "Governor RATE" line

In the "GOVERNOR" line, in case you have
switched on the function "Governor at CH8". In the
"Governor RATE" line, enter the appropriate offset
value for the desired rotor speed. The value to be
set depends on the governor that is used as well
as the desired target speed, and can of course be
varied for specific phases, for example:
