Piezo Helicopter Gyro
Item No.: 20 62 07
Intended Use
This gyro is a compact stabilising system which detects position changes thanks to a Piezo sensor.
Via integrated electronics a downstream servo is controlled to oppose the change of position.
The control commands generated by the gyro can be adjusted individually to any model using an
integrated speed controller and direction switch.
Due to the compact construction and the low weight, this system is ideal for smaller model
helicopters with electric drive.

Dear Customer,
These safety instructions are 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 Information
Caution, important note!
Operating models may cause damage to property and/or persons. Therefore, make
sure that you are properly insured when using the model, e.g. by taking out private
liability insurance.
If you already have private liability insurance, enquire whether the operation of the
model is covered before operating it.
Please note: In some countries you are required to have insurance for all model aircraft!
• The unauthorized conversion and/or modification of the product is inadmissible for safety and
approval reasons (CE).
• The product is not a toy and should be kept out of reach of children under 14 years of age.
• The product must not become damp or wet.
• Do not leave any packaging material unattended. It may become a dangerous playing material
for children!
b) Before operation
• Install the gyro in your model so that oscillation, vibrations and agitation can be prevented as best
possible.
• Check the functional reliability of your model and of the remote control system. Watch out for
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, check the settings of the trim slider on the transmitter for the different
steering directions and, if necessary, adjust them.
• Always switch on the transmitter first. Only then may the receiver with connected gyro be
launched. Otherwise the model or the servos might show unpredictable responses.
• Check the gyro before every use for correct function and secure fit in the model. A loose and
disconnected gyro makes the model uncontrollable.
c) During or after operation
• Do not take any risks! Your own safety and that of your environment is solely down to you being
responsible when dealing with the model.
• Improper operation can cause serious damage to people and property! Therefore make sure
there is sufficient safe distance to persons, animals or objects during operation.
• Select a suitable ground to operate your model.
• Fly your model only if your ability to respond is unrestricted. The influence of tiredness, alcohol
or medication can cause incorrect responses.
• Do not direct your model towards spectators or towards you.
• Never switch off the remote control (transmitter) while the model is in use. Always switch your
model off first, before switching off the remote control transmitter.
• In case of a defect or a malfunction, remove the problem before using the model again.
• Do not expose your model, the gyro and the remote control to direct sunlight or excessive heat
for longer periods of time.
Connecting the Gyro
Important information!
Do not launch your gyro before you have read the following sections in full and know
what must be observed during installation and operation. This is the only way to prevent
malfunctions or even damage.
The gyro (1) is connected to the IR socket plug (2) at the receiving output for the tail servo. The tail
servo (3) is connected to the gyro with the servo connection cable (4). This means that the gyro is
switched between the receiver and the tail servo.
Figure 1
Installation of the Gyro
When installing the gyro, make sure to select a place of installation where the gyro is well-protected
from vibrations and heat fluctuations. In many cases the manufacturers of the respective model
helicopter set the exact place of installation for the gyro.
If this is not the case on your model, select a place of installation which is close to the main rotor shaft.
The installation platform where you fit the gyro must be in a 90 degree angle to the main rotor shaft.
Only use a double-sided adhesive foam pad for attachment.
Figure 2
The stabilisation axle of the gyro (5) runs in parallel to the main rotor shaft (6) if installed correctly.
The settings regulator and the slide switches must be easily accessible from the top.
The cables connected to the gyro must be laid so that they cannot be caught in rotating parts of the
mechanics or be worn out on sharp edges. In practice, cable protection tubes have proven helpful.
Figure 2 shows an example for the installation of the gyro in a small electric helicopter with approx.
720 mm rotor diameter.
