FrSky V8 2.4GHz Radio Control System
Instruction Manual for V8 series
Thank you for purchasing the FrSky 2.4GHz RF radio control system. In order to fully enjoy benefits of this
system, please, carefully read the instruction manual and set up the devices as described below.
1. Brief Introduction
FrSky V8 2.4GHz radio control system is a new generation of radio control product developed by FrSky RC
Technology Co., Ltd. that incorporates the most advanced 2.4GHz digital communication technology. Thanks to
the high precision, minimum latency and interference resistant, the system makes the simultaneous use of multiple
devices without the risk of interference. Combining our software with FHSS we have developed a system
presenting the highest performance available.
We are glad to introduce the FrSky 2.4GHz Radio System.
ACCST (Advanced Continuous Channel Shifting Technology) is our advanced technology. The ACCST 2.4GHz
system shifts the frequency hundreds of times per second. It means there are no signal conflicts and interruptions.

Important!
The effective range of control refers to the distance between the transmitter and the receiver clear of
obstruction. All data was tested and verified by FrSky.
However this is not guaranteed due to many factors such as the flying environment and the weather, which
can greatly affect the effective range of control.
It is extremely important to range check your models prior to each flying session!
4. Setup and Operation process
4.1 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.
4.2 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.

4.3 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 GREEN 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 additional 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.
4.4 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
second, the RED LED of the transmitter module will change into GREEN, this moment, the power of the
transmitter module will be reduced to ab. 1/10-th of the nominal value, thus effective distance will be
shortened to just above 60 meter.
e) Walk away from the model while simultaneously operating the controls on the transmitter. Have an assistant
stand to confirm that all controls are completely and correctly operational. You should be able to walk ab. 60m
from the receiver without losing control.
f) Press the “F/S Range” button again, the range check will be finished.

4.5 Safety range indicator
When the model controlled by V8 2.4GHz radio control system is close to the maximum distance of control,
the response of the model will slow down. It is the safety feature designed by FrSky. It means, the user should fly
the model closer to the transmitter as soon, as the reactions are getting slower.
4.6 Signal loss indicator
In some special circumstances, such as a strong interference, the signal can be lost.
When signal lost in a short period, the receiver continues to try to search for the transmitter, at the same time,
keeps the last command from transmitter, until a new command is received.
Failsafe:
Our receivers support all the failsafe function for every channel. Just do it as bellow:
After the receiver has been bind, press briefly the “F/S Range” button of the receiver, the GREEN LED of the
receiver will flash twice, the failsafe is set up successfully.
If you do not need the failsafe function any more, just re-bind the receiver.
Attention: Controlling distance is affected by the environment too. Please test it in an open field away from any
obstacles. The controlling distance in the air is greater than that on the ground. Our controlling range is based on a
conservative ground test.

which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following
Measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
