It is extremely important to range check your models prior to each flying session!
3. Setup and Operation process
3.1 Installation of the transmitting module:
a) Remove the original transmitting module.
b) Put the FrSky 2.4GHz transmitter module into the module port of your RC transmitter and screw on the transmitting antenna.
c) Turn the transmitter power on and check the RF power indicators on the module and transmitter are working.
3.2 Installation of receivers:
The V8FR receiver incorporates two separate antennas into its design which enables it to receive the radio frequency transmission at
two different locations. The tip of the antenna cable is the receiving portion (the thinner part). If possible, please make sure that the two
antennas are placed at 90 degrees to each other.
Please note:
This is not a critical figure, however, the most important thing is to keep the antennas away from each other as much as possible. If
possible place the antennas away from metal, wires or carbon parts of the airframe to avoid signal lost. Tape or glue them in place so
they cannot move around.
As the wave length of 2.4GHz is shorter than older RC systems, its ability to go around solid obstacles is weaker than those with
frequencies that are below the 100MHz. Therefore, when you locate the antennas you must avoid objects as much as practical 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.
3.3 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) 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.
c) 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.
d) Turn off the transmitter finish the binding procedure.
e) Turn on the transmitter. Connect the battery to the receiver when ORANGE/RED LED on TX is on. The LED on the receiver will
indicate the receiver is receiving commands from the transmitter. In a few seconds system is ready to work (communication is
established).
After the steps above are completed, both the transmitter and receiver are ready to be used. Binding is required only to set up a new
link (like new or additi0onal receiver or transmitter module). Otherwise, just go to step e.
To control multi-receivers, every receiver should be programmed with the transmitter in binding state (step b). After all receivers are
binded, turn off the transmitter.
3.4 Range check:
For safe operation, it is necessary to perform pre-flight range check.
Caution must be paid when flying the unit in the neighborhood of metal fences, concrete buildings, or rows of trees. If doing so, you
may experience unexpected interferences.
Perform a range check as follows (Note: this is done with the receiver installed in the model):
a) Place the model at least two feet (60cm) above non-metal contaminated ground; for example a wooden bench.
b) Place the receiver’s antenna horizontally. Don’t let the antenna touch the ground.
c) Place the antenna of the transmitter in a vertical position.
d) Turn on the transmitter and receiver, then press and hold the “F/S Range” button of the transmitter for 4 seconds the RED LED of
the transmitter module will change into GREEN, the power of the transmitter module will be reduced to ab. 1/1000th of the nominal
value, and the effective distance will be shortened to ab. 1/30
th
of the normal value, thus effective distance will be shortened to just
