The GYRO MASTER is the new standard Ikarus gyro for RC models. This
gyro is the improved successor of our successful type Mini Gyro.
Progressive microprocessor technology together with an integrated
automatic internal stick authority system facilitate outstanding gyro action.
Gyro systems automatically compensate external forces (wind gusts) as
well as torque fluctuations acting on the model. They maintain the
momentary airplane flight position as far as possible unchanged. The gyros
are simply hooked up between the receiver output and the servo,
furthermore they are mechanically aligned parallel to the required correction
axis. The sensitivity is adjustable
potentiometer.
SPECIFICATIONS
The single channel GYRO MASTER comprises 1 input and 1 output. It is
assigned to stabilize 1 axis of your model.

CONNECTORS
The GYRO MASTER is equipped with the following connectors:

WIRING SCHEMATIC
The gyro is linked between servo and receiver. Plug the receiver connector of
the GYRO MASTER into one of the receiver output sockets. Connect the
servo to output 1 of the GYRO MASTER.

INSTALLATION
Choose a position of the GYRO MASTER far enough of vibrating or hot parts.
In order to inhibit vibrations stick the gyro with a relatively thick double sided
foam tape to a smooth surface.Cables to motor, speed controller and battery
should be routed as far away as possible of the GYRO MASTER. The gyro
compensates angular movements about the correction axis by means of
corresponding counter steering and must therefore be installed in correct
position referring to the axis about which the compensation takes place. In
order to achieve this effect the GYRO MASTER must be installed so that it´s
correction axis will be parallel with the demanded correction axis of the model
(see figures).
Alignment of the gyro axis in a HELICOPTER
In a helicopter the gyro usually controlls the tail rotor. Accordingly the tail
stands still even in strong side winds.

Vertical axis/tail control
Attention: Before first flight attempts check the direction of the gyro effect. In
case of a reversed direction of gyro effect your model may crash due to
uncontrollable pirouettes. If you rotate the helicopter clockwise about it´s
vertical axis the gyro must produce a tail rotor deflection which on the other hand
would produce an anticlockwise rotation of the model and vice versa.
Alignment of the gyro axis in a wing airplane
In this case the gyro is utilized to control the elevator or rudder. For beginners
the gyro is helpful in controlling the nose landing gear. The model in side wind
behaves similarly to no wind conditions.
Lateral axis/elevator
Alignment of the gyro axis in cars/boats
GYRO MASTER safely holds your model on it´s track. Drifting becomes much
safer. Unnecessary spin outs are avoided. Control during fast and straight runs
improves thanks to GYRO MASTER.

Operating instructions
Switch on the transmitter first and subsequently the power supply of the
receiver. After switching-on the GYRO MASTER executes an automatic
temperature compensation. During this period it is very important not to move
the gyro. At the end of this period (approx. 3 sec.) the LED lights up permanently
and the connected servo executes a short twitch. The gyro is ready for
operation.
Servo Reverse Jumper
With the aid of the reverse jumper the gyro effect can be reversed, with each
switching-on the microprocessor inquires the presence of a jumper.
Alternatively, the gyro operation can be reversed also by turning the gyro
rotation axis by 180 degrees.
Warranty
This quality product has been thoroughly checked before delivery. Nevertheless, in case of complaints your
warranty claims will be handled in accordance with our current General Sales Conditions. If equipment
returned for warranty repair shows full functionality during the entry inspection, handling charge will be
DM40,-. According to our experience the product works well with all current R/C systems. On the other hand
we cannot grant functionality with a specific R/C system due to the fact that control pulse conditions of
receivers are not liable to standardization. We must as well reject any responsibility for consequential
damage arisen from the use of our products since we are not able to supervise their appropriate
application.
Safety directions
The CE-label is no allowance for negligent handling of the equipment. Avoid dangerous areas of motors,
propellers, gears and rotor blades. Always consider electric systems as potentially dangerous. Always
remove the battery if you intend to work on the system. Avoid direct and condensed humidity. The product is
not protected against reversal of polarity. Reversing polarity or cables can entail irreparable damages.
Plugs and sockets must always fit perfectly. Improvisations can give rise to damages. Care about the power
consumption of the power supply, especially with regard to the gyro. A higher power consumption than
assigned for can damage the power supply and other equipment connected to it. Never disconnect an
electrical appliance from the battery as long as it is operating.
Operating directions
The transmitter must always be switched on first and subsequently the receiver. Make sre that the throttle
stick is in the low throttle position. In any case verify that you are exclusive user of the selected frequency
and nobody else is using it. Pay attention to the CE-labels of other components. Provide motors with at least
2 noise suppressing ceramic capacitors 10 - 100 nF/63 - 100 V and optional with further noise suppressing
means (filters, chokes). Route the antenna at least 1" away of motor, battery, speed controller and their
cables. Install the receiver as far away as possible of motor, battery and speed controller. Keep cables as
short as possible. Motor and battery cables should be twisted. For the purpose of storing your model remove
the batteries and store it at a dry place with normal air humidity. Should the system act erratically, disconnect
the flight battery from the system and reconnect it again after a waiting period of 5 - 10 s.
