Programming, Transmitter Without Proportional Controls; Initialising The Gyro - GRAUPNER GR-24 PRO 3xG+3A+3M+Vario Bedienungsanleitung

200%). This makes it a very easy matter to match the gyro's corrective effect to the model's
airspeed. In particular, higher gyro gain can be used for the landing approach - without the need
to switch flight phases.
• Now test-fly your model and fine-tune the values one by one until your preferred stabilising effect
is achieved without the model oscillating.
• It may be sensible or easier to activate the gyro for one axis only at first, and then to establish the
optimum setting for that axis, rather than for several axes simultaneously.

• Do not select a channel (Ch5 - Ch16); this function is only relevant to transmitters with proportional
controls.
• Move on to elevator or rudder and select the desired value (or OFF).
• Leave the settings for "Factor" and "Factor D" at OFF.
• It may be sensible or easier to activate the gyro for one axis only at first, and then to establish the
optimum setting for that axis, rather than for several axes simultaneously.
Once you have found the optimum settings, you can set up a transmitter switch to control the gyro, i.e.
for switching between gain settings. For example, you could assign a three-position switch to "Factor"
and "Factor D", and then use it to switch the values between 0% (OFF), 100% and 200%.
Flight phase specific settings
It is possible to use a channel to control the factor value by setting up flight phase specific transmitter
control settings, but only if the transmitter is an MX20 / MC20 or MC32; please see the instructions
supplied with your transmitter and refer to the "Transmitter control settings" and "Flight phase settings"
menu points for more information.

4.3 Initialising the gyro

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.
Your model is now ready to fly .. !

and carry out a test-flight. If gyro stabilisation is not
sufficiently pronounced, increase the value step by step
until the level of correction is as required; if the model
already oscillates, reduce the value step by step.
