The here mentioned sub-menu offers the possibility
of phase specifi c settings. Recognizable on the top
left side of the display in green color is displayed the
phase name. As standard is displayed the name of the
phase 1, which is indicated by the name "NORMAL"
or "PHASE 1". As soon as you will have defi ned one
or many other phases in the "PHASE" menu, you will
be able to switch among those phases. Activate the
corresponding switch or switches if desired to switch
between the phases.

This option may normally not be used for current

consult your gyro setting instructions since other-

This option can infl uence the effect of the gyro sensor

Sequence
suming that a gyro system is used in which the gyro's
effect can be set by the transmitter using an additional
channel, channel 7 in the Graupner/JR and Graupner
remote-control system. The gyro suppression reduc-
es the gyro's effect in a linear manner in proportion
to the defl ection of the tail rotor control stick corre-
sponding to the set value. If the gyro has not been
suppressed (at a value of 0%), the gyro's effect re-
mains independent of the control stick defl ection.
The gyro's effect can however be additionally varied
smoothly (depending on the phase if desired) between
a minimum and maximum using a control assigned in
the "Gyro" line in the
ple with one of the side proportional dials SL1 or SL2.
The maximum gyro gain occurs at the full defl ection of
the control and is zero at the opposite limit.

In the program, you are of course free to restrict the
effective range to both sides by setting the control
travel.
Depending on the position of the control, the gyro
gain is as follows in response to the full defl ection of
the tail rotor control control stick:
"Momentary control position
minus
the value of the gyro suppression".
If the gyro is in the neutral position and gyro suppres-
sion is set, the gyro's effect is accordingly reduced
from 100% to zero with increasing tail rotor excursion.
For values between 100% and a maximum of 199%,
full gyro suppression is achievable before full tail rotor
excursion (depending on the control position) (see the
fi gure after the next).
With the Graupner/JR-Gyro NEJ-120 BB, No. 3277,
both the bottom and top value are set: control 1 sets
the minimum gyro gain in the bottom position of the
servo, control 2 sets the maximum effect in the top
end position of the servo. The switch between these
two values occurs approximately in the center of the
servo travel.
The gyro systems PIEZO 900, PIEZO 2000 and PIEZO
3000 contrastingly feature proportional, infi nitely vari-
able adjustment of gyro gain (see the following exam-
ple graphs).
As an example, the option to confi gure phase-specifi c
– and static – gyro gain gives you the opportunity to
exploit maximum stabilization for normal, slow fl ying,
but to reduce gyro gain for fast circuits and aerobat-
ics.
