f) Setting the effective direction of the gyro
For the gyro to prevent the model helicopter from turning around the vertical axis (rotor shaft), it must
constantly give a tail servo control command to generate the opposite steering moment.
First switch on the transmitter, and then switch on the model.
If you use an electric model helicopter, disconnect the engine from the regulator in order
to prevent uncontrolled start-up of the rotors.
If the tail is now pushed to the left by hand as seen
from above, the tail servo must perform a control
movement to turn the tail back to the right. The rotary
motion of the tail servo must be in the same direction
as when the control stick for the tail function is moved
to the left (illustration 10 A) on the transmitter.
If the tail is now pushed to the right by hand as seen
from above, the tail servo must perform a control
movement to turn the tail back to the left.
The rotary motion of the tail servo must be in the same direction as when the control stick for the
tail function is moved to the right (illustration 10 B) on the transmitter.
If the rotational direction for the tail servo created by the gyro is exactly opposite to illustration 10,
you can change the rotational direction of the gyro.
However, the toggle switch only responds to the control pulses generated by the gyro. The control
pulses emitted by the transmitter and transferred by the receiver to the tail servo via the gyro are
not affected.
The toggle switch for servo direction (8) is the lower
micro switch at the right hand side of the gyro.
If needed, you can switch the rotational direction
from NOR (normal) to REV (reverse).
Take a small adjustment screwdriver to operate the
switch.
g) Setting maximum tail servo throw
To prevent the tail servo from being mechanically obstructed or limited when the control stick on the
transmitter is pushed all the way, maximum servo travel can be limited via a control dial.
Please note that these settings can only be made after the correct basic settings of the tail rotor
control rods have been made.
Move the control stick for the tail function all the way
to the right and all the way to the left alternately and
set the "ATV" control dial (6) so that the regulating
distance of the tail rotor is as great as possible. Note
that neither the servo nor the control rods must be
obstructed in their movement.
If the control dial is turned to the right, servo throw
increases.
If the control dial is turned to the left, servo throw
decreases.
Take a small adjustment screwdriver to make
adjustments.

Checking gyro sensitivity when flying
Before you launch the model on the airfield, allow the gyro to warm up to ambient temperature with
the receiver turned on. Switch off the receiver after approx. 5 minutes and then switch it on again.
Your gyro is now ready for use.
Operate the gyro in "head lock" mode at 100% gyro sensitivity and perform test flights at the same
rotor head rotation speed at which you will later fly.
a) Determining maximum gyro sensitivity
First fly your model helicopter forward as fast as possible. Then slightly deflect the control stick for
the tail function and let go of it suddenly so that it bounces around centre position.
If the tail straightens out without swinging up, gyro sensitivity can be increased. However, if the tail
swings up further, sensitivity is too high. The best sensitivity is achieved if the tail is just about to
swing.
Please note:
The maximum adjustable gyro sensitivity depends on the rotation speed of the main
rotor.
The higher the set main rotor speed, the lower the maximum flyable gyro sensitivity.

b) Determining optimal servo lever length
The length of the tail servo lever (see illustration 3, position 4) is directly linked to the maximum
possible gyro sensitivity.
If the servo lever is too long, the maximum possible gyro sensitivity is too low.
If the servo lever is too short, the maximum possible gyro sensitivity is too high.
If gyro sensitivity is below 70%, the servo lever should be shortened or the control rod should be
installed further to the inside of the servo lever.
If gyro sensitivity is above 100%, the servo lever should be extended or the control rod should be
installed further to the outside of the servo lever.
Once you have adjusted the length the tail servo lever, the maximum possible servo
travel must be readjusted using the "ATV" control dial (see illustration 12, position 6).
Otherwise there is a risk that the tail servo is damaged by overload.
c) Determining optimal vertical axis rotation speed
Fly a 540-degree turn with your model helicopter pushing the tail rotor control stick all the way.
How fast the model rotates around the vertical axis solely depends on the ATV value (transmitter
settings menu for maximum servo throw). If needed, you can decrease or increase this value via the
"dual rate" or the "exponential function" to adjust it to your individual control habits.

Care and maintenance

The exterior of the gyro may be cleaned with a soft, dry cloth only. Never use aggressive cleaning
agents or chemical solutions as these may damage the surfaces.
