Safety notices
transmitter's antenna directly toward the model will not
produce good reception but rather degrade reception.
When multiple remote controls are operating
simultaneously, pilots should position themselves in a
loose group. Pilots standing off to themselves not only
endanger their own models but those of others as well.
However, when 2 or more pilots using 2.4 GHz remote
control systems are closer than 5 m to one another this
can lead to return channel overdrive which, in turn, will
trigger a range warning much too early. Increase your
distance between one another until the range warning
ceases.

Pre-start checks
Before switching the receiver on, ensure that the gas
control is at its Stop/Idle position.
Before switching the receiver on, ensure that the gas
control is at its Stop/Idle position.
Always switch the transmitter on fi rst and then the
receiver.
Always switch the receiver off fi rst and then the
transmitter.
If this sequence is not maintained, such that the receiver
is still switched on when the corresponding transmitter
is switched to "OFF", then the receiver may respond to
other transmitters or general radio frequency noise. This
can cause the model to execute uncontrolled operations
that may cause personal injuries and/or property
damage.
In particular, for models equipped with a mechanical
gyro:
before switching off the receiver, disconnect the model's
power supply to prevent the motor from revving up
unintentionally.

The residual spin of a gyro often produces so much
voltage that the receiver may falsely interpret a
throttle signal! This will then cause the motor to
start up unexpectedly.

Range test
Perform checks for proper operation and range before
every session. Secure the model adequately in place
and ensure that no one is in front of the model.
Perform a complete functional test on the ground and
execute a complete simulated fl ight to exclude the
possibility of system faults or problems with the model's
programming. When doing this, be sure to follow the
notices provided on pages 71 and77.
Never operate the transmitter in Model mode, i.e.
for fl ying or driving, without an antenna. Be sure the
antenna is fi rmly seated in its socket.

Operating a winged aircraft, helicopter, ship or car
Never fl y over spectators or other pilots. Never endanger
humans or animals. Never fl y in the vicinity of high-
voltage wires. Do not operate the model in the vicinity of
sluice locks or where real boats or ships are operating.
Do not operate a model on public streets or highways,
paths or plazas, etc.

Monitoring transmitter and receiver batteries
You must stop running the model to recharge the
transmitter's battery no later than when low transmitter
battery voltage triggers the "Batt must be recharged!!"
display and acoustic signal.
Check the charge in batteries routinely, particularly the
receiver's battery. Do not wait until the movements of
controlled mechanisms are noticeably slower. Replace
expended batteries before they cause problems.

Routing the receiver's antenna
The receiver and its antennas must be positioned as far
away as possible from drives of any kind. If the model's
hull is made of carbon fi ber material, the ends of the
antennas must extend outside of the hull.
The orientation of antennas is not critical. Nevertheless,
a vertical (upright) installation of receiver antennas is
advantageous. In the case of diversity antennas (two
antennas), the second antenna should be oriented at a
90° angle to the fi rst antenna.

Servo installation
Always mount servos with the provided rubber vibration-
damper parts. Only in this manner can these parts be
protected against excessively hard vibrations.

damper parts. Only in this manner can these parts be

Installing control rods
Control rods must be installed such that they operate
freely and smoothly. It is particularly important that all
rudder levers are able to move to their full limits, i.e. not
otherwise mechanically blocked.
In order to be able to stop a running motor at any time,
control rods must be adjusted such that the carburetor
tap is completely closed when the joystick and trim lever
are brought into their end idle position.
Pay attention that no metal parts, e. g. as a result of
rudder actuation, vibration, rotating parts, etc., rub
against one another. Metal-to-metal contact causes
electrical "noise" which can interfere with the correct
operation of the receiver.
