FrSky TWIN X14 Transmitter Dual 2.4G Radio System User Manual

Introduction

DUAL 2.4G RADIO SYSTEM
The TWIN X14 stands out as a robust radio system, boasting the capability of utilizing dual 2.4G frequencies 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 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 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 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 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 boasts built-in 128MB 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 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 X14 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.

ETHOS Operating System

Create the model

Model Setup Procedure – Internal Module

Then turn the state of Internal RF to On. Set the binding mode for the Internal RF module corresponding to the receiver (ACCST D16, ACCESS, TW MODE.etc).

The system assigns the receiver a number for the receiver (Model ID) automatically while creating a new model. ( The Model ID can be set from 00 to 63, with the default ID being 1.)

Reset: Registration procedure is not required to repeat anymore after the receiver was once registered even though the receiver is deleted. Pressing the [Reset] and repower the receiver can have the bound recovered.

Range Check

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.

How to set Failsafe

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.

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.

FLYING SAFETY

Warning:

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.

Battery

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.

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.

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.

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.

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.

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.
