Intended use
This gyro system is a compact stabilising system which detects position changes thanks to a Piezo
sensor. The integrated electronics controls a downstream servo to work against changes in
position. Due to its compact construction, this system is ideal for small electric helicopters.
The gyro can be used either in "normal" mode or in "head lock" mode.
In "normal" mode, the downstream servo is corrected as long as the rotary movement of the model
is recognised by the gyro.
In "head lock" mode, the downstream servo is corrected until the original starting position (angular
position) of the gyro has been reached again.
The gyroscopic effect is adjustable either via the transmitter or the built-in control dial.
The gyro with order no. 206484 is designed for use with analogue servos; the gyro with order no.
206485 is designed for use with analogue or digital servos.

Safety instructions

The guarantee/warranty will be void if damage is incurred resulting from non-
compliance with these operating instructions. We assume no liability for any
consequential damage!
We do not assume liability for personal injury or material damage resulting from
improper use or disregarding the safety instructions! In such cases the warranty/
guarantee is voided.
Normal wear and tear as well as damage caused by accidents or crashes are also
excluded from the guarantee and warranty.
Dear Customer,
These safety instructions are intended not only for the protection of the product, but also
for your own safety and the safety of others. Therefore read this chapter very carefully
before putting the product into operation!
a) General
• The unauthorized conversion and/or modification of the product is inadmissible because of safety
and approval reasons (CE).
• The product is not a toy. It is not suitable for children under 14 years of age.
• The product must not get damp or wet.
• Taking out private liability insurance is recommended. If you already have insurance, enquire
whether the operation of the model is covered.
• Do not leave packaging material lying around unattended. It can become a dangerous toy for
children.
b) Before operation
• Install the gyro in your model so that oscillation, vibration and agitation can be reduced as
effectively as possible.
• Check the functional reliability of your model and of the remote control system. When doing so,
make sure there is no visible damage such as defective plug connections or damaged cables. All
moving parts of the model must run smoothly, but should not have any play in their bearings.
• Before each operation, control the settings of the trims on the transmitter for the different steering
directions and, if necessary, adjust them.
• Always switch the transmitter on first. Then the receiver with the gyro connected to it may be
switched on. Otherwise the model or the servos might show unpredictable responses.
• Before every use, check the gyro for correct function and make sure it sits properly in the model.
The model cannot be controlled if the gyro is loose or disconnected.
c) During or after operation
• Do not take any risks! Your own safety and that of your surroundings depend on your responsible
handling of the model.
• Improper operation can cause serious damage to people and property! Therefore, during
operation, make sure there is sufficient safe distance to persons, animals or objects.
• Select a suitable area to operate your model.
• Do not steer your model towards spectators or towards yourself.
• Always leave the remote control (transmitter) turned on as long as the model is in operation.
Always switch off your model first before switching off the remote control.
• In case of a fault or a malfunction, solve the problem before using the model again.
• Do not expose your model, the gyro and the remote control to direct sunlight or excessive heat
over a longer period of time.

Connections and control elements

Important information!
Do not operate the gyro before you have read the following chapters completely and
know what has to be observed during installation and operation. This is the only way to
prevent malfunctions or even damage.

The gyro is connected to the receiver output for the
tail servo. The tail servo itself is connected to the gyro
system directly. This means that the gyro is connected
between the receiver and the tail servo. In addition,
the gyro is connected to another receiver output

which is used later to set the sensitivity.
1 Receiver connection for gyro sensitivity*
2 Receiver connection for the tail servo
3 Gyro
4 Double-sided adhesive foam
5 Connection pins for the tail servo
6 Control dial for maximum servo throw
7 Toggle switch for analogue/digital servos (only
applies to the gyro with order no. 206485)
8 Toggle switch for servo direction
9 LED display
10 Control dial for gyro sensitivity
*) If this connection is plugged into the receiver, the gyro will operate in dual mode. In this mode,
gyro sensitivity is set via the transmitter. The gyro can then be used either in "normal" mode or in
"head lock" mode.
If this connection is not used, gyro sensitivity is set via the "GAIN" control dial on the gyro. The gyro
will then operate in "head lock" mode only.

Installation of the gyro
When installing the gyro, ensure that you select a place of installation where the gyro is well
protected from vibrations and heat variations. In many cases, the manufacturers of model
helicopters predefine the exact place of installation for the gyro.
If this is not the case with your model, select a place
of installation which is close to the main rotor shaft
(11). The installation platform (12) where you install
the gyro must be in a 90° angle to the main rotor
shaft. Only use the provided double-sided adhesive
foam (4) for installation.
The stabilising axle (13) of the gyro then runs parallel
to the main rotor shaft.
The control dials and the trims have to be easily
accessible from the side.
The cables connected to the gyro must be laid so that they cannot get in contact with moving parts
or be worn by sharp edges.
Illustration 2 shows the correct installation of the gyro with order no. 206485 in a small electric
helicopter of approx. 720 mm rotor diameter.

Installation of the tail servo
The installation of the tail servo (14) and the
adjustment of the tail rotor are normally set out
precisely in the instructions of the model helicopter.
Important information!
In order for the gyro to work most
effectively, the servo lever (15) and the
linkage rod (16) must be in a 90° angle to
one another (neutral position).
The distance (A) depends on the model size and is
normally stated in the documents of the model
helicopter.
Ensure an absolutely smooth and free-of-play control of the tail rotor. The gyro will only work ideally
if even small servo throws cause a control response on the model.
