Instruction Manual for FrSky TWIN X14/X14S
DUAL 2.4G RADIO SYSTEM
The TWIN X14/X14S stands out as a robust radio system, boasting the capability of utilizing dual 2.4G frequen-
cies simultaneously on the same receiver in TW mode. Different from standard active-standby redundancy
solutions, the TW active-active protocol ensures both 2.4G frequency bands are actively engaged on the TWIN
series RF module and receiver simultaneously.
Equipped with two internal 2.4G RF antennas, the TWIN X14/X14S offers expansive multi-directional coverage
for transmitting signals. Leveraging these attributes alongside the exterior antenna mounting frame, the Twin
system provides less latency, higher reliability, and faster data rates with confidence. In addition to the TW mode,
TWIN X14/X14S also supports ACCST D16 and ACCESS modes, this means users can benefit from a wide
range of compatible receiver options to choose from and bind to when building the RC model.
ERGONOMIC, COMPACT & FLEXIBLE DESIGN
In alignment with the form factor concept of TANDEM X18, the TWIN X14/X14S has been crafted to enhance its
portability, reduce weight, and streamline its design. The ergonomic layout ensures that the momentary buttons,
shoulder sliders, and switches on the top are effortlessly accessible.
The TWIN X14/X14S offers 4 customizable buttons, thoughtfully placed at the radio panel center for real-time and
frequent operations. Take, for instance, when flying an RC glider, to configure these buttons as additional Trim
functions by ETHOS, these buttons become invaluable for on-the-fly adjustments then, allowing pilots to adapt
the angle of the flaps/surface according to the real-time air environment.
BUILT-IN FLASH STORAGE AND RECHARGING SYSTEM | STAND HOLDER ATTACHABLE STRUCTURE
DESIGN
Eliminating the need for users to fret over storage decisions, the TWIN X14/X14S boasts built-in 128MB/512MB
flash storage, providing ample space for your file storage requirements. Its practicality extends to a battery bay
accommodating a 2600mAh Li Battery, easily replaceable and featuring a Type-C port for recharging.
Further enhancing its user-friendly design, the TWIN X14/X14S introduces an attachable and foldable structure
on the rear shell. This design allows for the easy installation of an additional stand holder accessory, transforming
the TWIN X14/X14S not only can be conveniently carried but it can also to be positioned anywhere, offering
operational flexibility without having to hold the radio in your hands.

Note:
● If the failsafe is not set, the model will always work with the last working status before the signal is
lost. That could cause potential damage.
● When the failsafe is disabled on the RF module side, the failsafe set on the receiver side will be
applied.
● SBUS port does not support the failsafe setting in No Pulses mode and always outputs signal.
Please set "Hold" or "Custom" mode for the SBUS port.
There are 3 failsafe modes when the setting is enabled: No Pulse, Hold, and Custom mode.
● No Pulses Mode: On loss of signal, the receiver produces no pulses on any channel. To use this mode, select
it in the menu and wait 9 seconds for the failsafe to take effect.
● Hold Mode: The receiver continues to output the last positions before the signal was lost. To use this mode,
select it in the menu and wait 9 seconds for the failsafe to take effect.
● Custom Mode: Pre-set to required positions on the lost signal. Move the cursor to the failsafe mode of the
channel and press Encoder, then choose the Custom mode. Move the cursor to the channel you want to set
failsafe On and press Encoder. Then rotate the Encoder to set your failsafe for each channel and short-press
the Encoder to finish the setting. Wait 9 seconds for the failsafe to take effect.
How to set Failsafe
A pre-flight range check should be done before every flight, in case the signal loss is caused by the reflection of
the signal by the nearby metal fence or concrete, and the shading of the signal by buildings or trees during the
actual flight. Under normal circumstances, in Range Check mode, the RSSI at 150m is about 45-50.
1. Place the model at least 60 cm (2 feet) above the non-metal contaminated ground (such as on a wooden
bench). The receiving antenna should be in a vertical position.
2. Ener the ETHOS system, move to the "RF System", scroll the Encoder to select "RANGE" mode and press
Encoder. In range check mode, the effective distance will be decreased to 1/30.

Instruction Manual for FrSky TWIN X14/X14S
Make sure your transmitter can’t tip it over. If it is knocked over, the throttle stick may be accidentally
moved, causing the engine to speed up. Also, damage to your transmitter may occur.
At the flying field
To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:
1. Pull throttle stick to idle position, or otherwise disarm your motor/engine.
2. Turn on the transmitter power and allow your transmitter to reach its home screen.
3. Confirm the proper model memory has been selected.
4. Turn on your receiver power.
5. Test all controls. If a servo operates abnormally, don’t attempt to fly until you determine the cause of the
problem.
6. Start your engine.
7. Complete a full range check.
8. After flying, bring the throttle stick to idle position, engage any kill switches or otherwise disarm your
motor/engine.
If you do not turn on your system on and off in this order, you may damage your servos or control surfaces, flood
your engine, or in the case of electric-powered or gasoline-powered models, the engine may unexpectedly turn
on and cause a severe injury.
Where to Fly
We recommend that you fly at a recognized model airplane flying field. You can find model clubs and fields by
asking your nearest hobby dealer.
Using a fully charged battery (DC 6.5~8.4V). A low battery will soon die, causing loss of control and a crash.
When you begin your flying session, reset your transmitter’s built-in timer, and during the session pay attention
to the duration of usage. Also, if your model used a separate receiver battery, make sure it is fully charged before
each flying session.
Stop flying long before your batteries become over discharged. Do not rely on your radio’s low battery
warning systems, intended only as a precaution, to tell you when to recharge. Always check your
transmitter and receiver batteries prior to each flight.
Battery
Always pay particular attention to the flying field’s rules, as well as the presence and location of
spectators, the wind direction, and any obstacles on the field. Be very careful flying in areas near power lines, tall
buildings, or communication facilities as there may be radio interference in their vicinity.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part

CE
To ensure the safety of yourself and others, please observe the following precautions.
Have regular maintenance performed. Although your TANDEM X20 HD protects the model memories with
non-volatile EEPROM memory (which does not require periodic replacement) and of a battery, it still should have
regular check-ups for wear and tear. We recommend sending your system to your FrSky Service Center annually
during your non-flying-season for a complete check-up and service.

FrSky is continuously adding features and improvements to our radio systems. Updating (via USB Port or the
Micro SD card) is easy and free. To get the most from your new transmitter, please check the download section
of the FrSky website for the latest update firmware and guide for adjusting your sticks. (www.frsky-rc.com)
Updates
In order to maintain complete control of your aircraft it is important that it remains visible at all times. Flying
behind large objects such as buildings, grain bins, etc. must be avoided. Doing so may interrupt the radio
frequency link to the model, resulting in loss of control.
Do not grasp the transmitter's antenna during flight. Doing so may degrade the quality of the radio frequency
transmission and could result in loss of control.
As with all radio frequency transmissions, the strongest area of signal transmission is from the sides of the
transmitter's antenna. As such, the antenna should not be pointed directly at the model. If your flying style
creates this situation, easily move the antenna to correct this situation.
Don’t fly in the rain! Water or moisture may enter the transmitter through the antenna or stick openings and
cause erratic operation or loss of control. If you must fly in wet weather during a contest, be sure to cover your
transmitter with a plastic bag or waterproof barrier. Never fly if lightning is expected.
