Initialising The Gyro (Plane); Free Mixer - GRAUPNER GR-18 Notice D'utilisation

initialising the gyro (plane)

After switching on the model of the gyroscope is immediately active but not yet initialized. To initialize it, you keep your
model when switching quiet and straight in level flight - the best place it on the flat ground or a flat table. After about 2
seconds, the ailerons move up and down just once. This "wiggle" signaled the successful initialization, the end of the
calibration, only then the model may be moved again.
All sticks are to be kept strictly in neutral!
WARNING: during the initialisation phase the gyro detects the model's neutral attitude, and for this reason it
is absolutely essential to leave the model in its 'normal flight attitude' during the activation phase, and avoid
moving it! If you neglect this, the gyro may detect an incorrect flight attitude, with the result that the model will not fly
as you expect it to. It may be difficult to control, and could even crash!
During the initialisation phase the receiver also detects the centre points of the individual control channels; this
information is used for gyro suppression. Gyro suppression reduces the stabilising action progressively as the
transmitter controls are deflected away from centre; at +/- 100% the gyro is completely disabled.

MIXER: up to four mixers can be programmed simultaneously. You can switch between Mixer 1, Mixer 2, ... and mixer
4 in the "Mixer" line.
The following settings only affect the mixer selected in this line.
FROM CHANNEL: the signal present at the signal source (or source channel) is mixed in to the target channel (TO
CHANNEL) to an extent which can be set by the user. The method of setting up the values is analogous to the "Free
mixers" menu in HoTT transmitters.
TO CHANNEL: part of the source channel signal (FROM CHANNEL) is mixed into the target channel (TO CHANNEL).
The mixer ratio is determined by the percentage values entered in the "TRAVEL-" and "TRAVEL+" lines. Select "0" if
you do not require the mixer.
Mixer ratio (TRAVEL-/+): in these two lines you can define the mixer ratio in relation to the source channel (FROM
CHANNEL); the value is set separately for both directions.

these control surfaces, since the gyro stabilisation system will have no effect

the gyros. If you have already programmed mixer functions in the "Wing

that those mixers do not overlap with those available in this menu!
