6.1.2 Installation of receivers:
The D8R receiver incorporates two separate antennas which enable them to
receive the radio signal at two different locations. Please make sure that the two
antennas are placed apart and oriented 90 degrees to each other.
Please note:
As the wave length of 2.4GHz is shorter than older RC systems, its ability to go
around solid obstacles is weaker than 72 or 36 MHz. So the antennas must avoid
objects with high conductivity, such as metal parts, servos, ESC’s, battery packs, wires,
and carbon fiber structures. If possible put the tip of the antennas outside of the fuselage
for maximum reception.
6.1.3 Receiver and Transmitter Setup Instructions:
Follow the steps below to properly set up your system.
a) Turn your FUTABA or JR transmitter on and switch it to PPM mode, power off the
TX.
b) Check the working mode of the Tx module.
c) Turn the transmitter on while holding the programming button. Release it a few
seconds later. The RED LED on the transmitter module will flash indicating the
transmitter is ready to bind the receivers.
d) Connect the battery to the receiver while holding the receiver’s button. The LED on
the receiver will flash indicating the binding process is complete. Turn off the receiver.
e) Turn off the transmitter and receiver to finish the binding procedure.
f) Turn on the transmitter.
g) Connect the battery to the receiver, the Green LED on the receiver will indicate the
receiver is receiving commands from the transmitter.
After the steps above are completed, both the transmitter and receiver are ready to
be used.
