diversity antennas (two antennas), the active end of the
second antenna should be at a 90° angle from the end
of the first antenna, and the distance between the active
ends should ideally be more than 125 mm.
Installing the servos
Always install the servos with the provided rubber
vibration damper as shown in the "Installation
instructions" on page 34. This is the only way to
protect them somewhat from excessive vibration.
Installing the linkages
The linkage must be installed so that it is unhindered
and can move easily. It is particularly important for all a
rudder levers to execute their entire range of movement
without any mechanical restrictions.
To make it possible for running motors to be stopped
at any time, the linkage must be adjusted so that the
carburettor is completely closed when the throttle
control stick and trim are moved into idling end position.
Make sure that no metal parts rub against each other
when moving the rudder, vibrations, rotating parts, etc.
This may produce glitches and malfunction of receiver.
Aligning the transmitter antenna
The field strength emitted from the transmitter antenna
when it is pointing in a straight line is weak. It is there-
fore incorrect to point the transmitter antenna directly to
the model in the belief that this will increase reception.
When a number of remote control systems are being
used at the same time, the pilots should stand next to
each other in a loose group. Pilots standing away from
the group pose a danger both to their own model and
those of others.
If two or more pilots are using a 2.4 GHz remote control
system and are closer than 5 m from each other, it can
cause interference with the feedback channel, and a
range warning may be generated too early. The pilots
should move away from each other until the range
warning stops.
Checklist before starting
Before turning on the receiver, make sure that the
throttle control stick is at stop/idle.
Always switch on the transmitter before the receiver.
Always switch off the receiver before
switching off the transmitter.
WARNING:
If this sequence is not observed and the
receiver is switched on while the associa-
ted transmitter is "OFF", the receiver can
respond to other transmitters, interference, etc. This
can cause the model to move in an uncontrolled
manner and cause property damage or personal
injury.
When models have a mechanical gyro, the following
holds true:
Before turning on your receiver, make sure that the
motor cannot start unintentionally by disconnecting the
power supply.
When the gyro is running down, it frequently
generates so much voltage that the receiver thinks
that the throttle signals are okay. This can cause the
motor to start unintentionally.
Range and function test
Before every use, check the range and
functioning. Firmly secure the model, and
make sure that no one is nearby.
Perform at least one complete range and function
test on the ground, and run through an entire flight
simulation to determine if there are any problems with
the system or the programming of the model. Follow the
instructions on page 77.
WARNING:
If the range and function test as well as the
flight simulation are not performed
completely and conscientiously,
malfunctions may go unrecognized and
reception may be lost which could cause a loss of
control or even cause the model to crash. This
can result in major property damage and/or
personal injury.
Operating models: Airplane, helicopter, ship and
automobile
WARNING:
•
Never fly the model over the heads
of observers or other pilots. Never
endanger people or animals. Never fly
close to power lines. In addition, never operate
your model close to locks and open nautical
traffic. Do not operate your model on open roads,
highways, paths, public walkways, etc.
•
Never switch off the transmitter while operating
the model! If this nonetheless accidentally
happens, do not panic, and wait until the
transmitter display goes dark which indicates
that the transmitter is completely off. This will
take at least 3 seconds. After this time, switch on
the transmitter again. Otherwise, the transmitter
may freeze directly after being switched on,
and you will be unable to control the model.
The transmitter may only be switched on again
after it has been switched off and the described
procedure has been correctly repeated.
Towing
WARNING:
When operating towed models, maintain a
minimum distance of approximately 50 cm
between the participating receivers. Using
the satellite receiver is an option. Otherwise,
malfunctions from the feedback channel are
possible.
Checking the transmitter and receiver batteries
Stop operation and recharge the transmitter
battery at the latest when the
transmitter battery is running low, the
message " Charge the battery!" appears in the display,
and an acoustic warning sounds.
Regularly check the battery charge, especially of the
receiver battery. Do not wait until the movements of
