case that works you may fly!!! Otherwise
you will have a destabilisation, instead of
stabilisation and will have to set the servo-
reverse on some or on all servos:
The servo-reverse is made in the setup-
mode by nick-, roll- and sense-commands
from your transmitter. If you do not have a
free channel for sense, you can disconnect
the tail servo and use its channel for sense
during the settings, after that connect the
tail servo again.
1. The sense cable of the Stabilizer must be
connected to the receiver. If you do not
have a free channel for the sense, discon-
nect the tail servo and use its channel for
the sense during the settings. No mixers
should be programmed on the sense chan-
nel. If you have already programmed mixers
on sense, you can use the tail servo chan-
nel for sense during the settings.
2. Switch the transmitter on.
3. Push the button on the sensor unit and hold
it pushed down.
4. Switch on the receiver, hold for min. 5sec
the button pushed and than release it. The
LED will blink 3-times with pauses. You are
now in the setup mode for the servo
reverse.
5. By giving of Sense-command from your
transmitter (changing the sense value) you
mirror only the nick-corrections of Roll2, the
second roll-servo referable to Roll, the first
roll-servo. The nick-corrections of the two
roll servos servos must be opposite to the
nick corrections of the nick servo, but this
is set under point 6. Point 5. is is not rele-
vant for 90° swashplates.
6. If the direction of the nick-servo corrections
must be reversed – give once a full nick
command, than go back again to the nick
middle position, the LED blinks 1-time or 2-
times, depending on the side you have
moved the nick-stick to. After ca. 3sec the
LED will blink 3-times (double blink) with
pauses again.

1.single blinking: all 3 servos are
reversed (mirrored) if you have 120°
swashplate; if you have a 90°
swashplate with one roll- and one
nick-servo - only the one nick-servo
will be reversed (mirrored).

7. If the direction of the roll-servo-corrections
must be reversed – give once a full roll com-
mand, than go back again to the roll middle
position, the LED blinks 4-times or 5-times,
depending on the side you have moved the
roll-stick to. After ca. 3sec the LED will blink
2-times (double blink) with pauses again.

the 5-times blinking not relevant, no
changes are made.
8. Switch off the receiver, the settings will be
permanently saved. You can repeat the
points 5. to 7. as long as necessary.
Tipp:
If you are not sure, what has to be done to
have all servos work properly, than make
only one servo reverse and try what the
result is. After that make the next servo
reverse, if necessary and try again the
result.
5.2. Sense
1. If there is a free channel on transmitter and
receiver, you can connect the sense cable
to this channel and change the sense of the
Stabilizer during the flight (0% - channel
middle, no stabilisation; +100% - max. sta-
bilisation.) The area from -100% to -75% is
used for horizon calibration in the air and
have to be used only if explicit desired, no
corrections from the Stabilizer are mixed to
the commands of the pilot in that sense
range. This is a good way to set the propor-
tion of the influence of Stabilizer during the
flight.
2. For aerobatic flight the sense of the Stabili-
zer must be reduced from the set value (for
example +65%) with increasing roll- and/or
nick- commands. Otherwise the electronics
will always try to keep the helicopter in hori-
zontal position. This is achieved with pro-
