Concerning the connection and incorporation of
the servos and the power source
Receiver Connection
Preparation
Since the receiver is susceptible to vibration, shock, and water,
anti-vibration and waterproofing measures should be securely
implemented.
•
If the connectors become detached while flying, there will be a
risk of uncontrolled operation. Please securely insert all of the
connectors as far as they will go.
•
In the situation where relay connectors (extension leads) are
used during the installation rubber sponge should be wrapped
round the connectors to fix them.
Be absolutely sure not to leave the connectors hanging
unsupported.
•
In JR receivers, the channels for connecting servos are given names rather than numbers.
From this point onward in the manual the receiver channels are described using their names, so be careful of this when reading the manual.

Built-in Antenna
Circuit Board Face
Due to the 2.4GHz band which has a strong directionality in
its radio waves, the receiving sensitivity will greatly differ
depending on the direction against the antenna. Since the
antenna receives radio waves from the sides rather than
from the tip, please take adequate care of the antenna
direction when installing the antenna in the model.
In the case where there are two coaxial antennas in the receiver
main unit, the faces of each antenna should be installed so that
they are at right angles to each other, rather than being parallel.
Note that in order to allow certain and stable communications to
be carried out, it is recommended that each antenna should be
installed with a separation of 30mm or more.
If each antenna is installed in parallel, the
receiving efficiency will be reduced.
The built-in antenna of the remote antenna is
installed on the surface of the circuit board.
Care will be required in the situation where the
built-in antenna has been installed beside a
shielding material, since the receiving
sensitivity will be considerably degraded.
* The remote antenna receives the data and also
feeds back to the transmitter.
The antenna part should be installed
in a perfectly straight condition.
Coaxial part of the antenna can
be bent however, do not bend it
in a right angle. This will damage
the internal antenna wires.
In the situation where the antenna has been
attached directly to a shielding material such
as carbon or metal, the receiving sensitivity
of the installed antenna surface will be
considerably reduced. When the antenna is
to be installed on this kind of shielding
material, either separate the antenna as far
as possible from the material, or in the case
where the radio wave shielding material is
the aircraft body itself project the antenna
outside the aircraft body.
* Take care not to
damage the
antennas
projecting from the
aircraft body.

shielding material.
* When using a gyro, carry out the
connection according to the gyro
operation manual.
