HELLORADIO is therefore aimed at RC enthusiasts looking for a customisable, upgradeable transmitter suitable for both recreational flying and complex RC configurations.

Why choose a HELLORADIO RC transmitter?

Choosing an RC transmitter depends on several criteria: the number of channels required, receiver compatibility, stick precision, programming capabilities and ease of use in the field.

HELLORADIO transmitters meet these requirements through modern electronic architecture combined with EdgeTX software.

This software allows pilots to create customised control configurations without being restricted to the predefined mixes generally offered by traditional transmitters.

The V15 and V16 ranges can manage up to 32 logical channels with EdgeTX.

However, the number of channels actually available depends on the transmission protocol, the selected receiver and the model's configuration.

This programming flexibility is particularly useful for RC aircraft pilots using multiple aileron servos, flaps or retractable landing gear.

It is also suitable for competition gliders, helicopters and radio-controlled models requiring specific functions.

HELLORADIO transmitters also stand out for their different radio transmission options.

ExpressLRS versions focus on responsive, configurable transmission, while models equipped with a 4-in-1 multiprotocol module can operate with numerous existing receivers, subject to compatibility.

For an RC enthusiast comparing a HELLORADIO transmitter with Futaba, RadioMaster, Jeti or Graupner, the key factors are therefore the transmission system, ergonomics, software capabilities and equipment genuinely required for their particular application.

Comparison table of HELLORADIO V15 and V16 RC transmitters

When choosing between a HELLORADIO V15 Standard, V15 MAX, V15 ULTRA, V16 PRO or V16 MAX, it is useful to compare the features that directly affect RC modelling activities.

The following table highlights the main differences between the five models, using the V16 4-in-1 versions presented here as the reference.

These specifications apply to the versions described and may vary depending on the product reference, installed RF module, battery used and software updates.

Specific functions should be checked on the product page of the selected transmitter.

ExpressLRS or 4-in-1 multiprotocol: which radio link should you choose?

ExpressLRS: a responsive and configurable RC transmission protocol

ExpressLRS, commonly abbreviated as ELRS, is an open-source radio control system designed to transmit pilot commands with low latency and a range suitable for different RC modelling applications.

It is used particularly on FPV drones, RC aircraft, gliders and other models requiring a configurable radio link.

Transmission parameters, output power and available refresh rates depend on the hardware, firmware and applicable regulatory requirements.

For pilots looking to buy a long-range ExpressLRS RC transmitter, it is important to check compatibility between the transmitter and receiver, their frequency bands and software versions.

An ExpressLRS link does not guarantee a specific range on its own. The usable distance depends particularly on the antennas, their orientation, the radio environment, obstacles and installation conditions.

Gemini Dual Band: using two frequency bands

HELLORADIO V15 transmitters incorporate an ExpressLRS Gemini Dual Band module which, depending on the configuration, allows operation on the 2.4 GHz and 868 MHz bands.

With a compatible Gemini X receiver, the system can use both bands simultaneously to improve radio link diversity.

This approach is useful for complex radio-controlled models, particularly when pilots want multiple transmission paths.

However, dual-band operation does not eliminate every risk of signal loss.

Correct antenna installation, reliable receiver power and range testing remain essential.

The choice of frequencies and transmission power must also comply with the regulations applicable in the country of use.

4-in-1 multiprotocol technology for keeping your existing RC receivers

A 4-in-1 multiprotocol transmitter uses a radio module capable of supporting several families of transmission protocols on 2.4 GHz.

This solution is particularly useful for RC enthusiasts who already own several aircraft, helicopters or other models equipped with receivers from different manufacturers.

The HELLORADIO V16 PRO and V16 MAX 4-in-1 versions may support certain Futaba SFHSS, FrSky, FlySky, Spektrum DSMX, Graupner HoTT receivers and other compatible protocols.

Support depends on the exact receiver model, its firmware and the protocol used.

Compatibility with a particular brand therefore does not mean that all receivers from that manufacturer will work with the module.

European LBT versions must also be distinguished from other transmission variants.

Before use, it is necessary to consult the compatibility list and perform functional and range tests.

Adding an external JR-format RF module

HELLORADIO V15 and V16 transmitters feature a slot for adding a compatible external JR-format RF module, subject to its electrical and software specifications.

This makes it possible to use another protocol, for example with an ExpressLRS, multiprotocol, Crossfire or Ghost module compatible with the transmitter.

The external module must be purchased separately if it is not included in the chosen configuration.

For pilots wishing to retain their existing receivers while adopting ExpressLRS for new models, this modularity can avoid the immediate replacement of all their equipment.

EdgeTX: open-source software for programming your RC transmitter

Creating custom mixes for RC aircraft, gliders and helicopters

EdgeTX is open-source software used on various programmable RC transmitters, including HELLORADIO and certain RadioMaster models.

It allows pilots to assign the transmitter's physical controls to the required channels and create mixes suited to the operation of the radio-controlled model.

On an RC aircraft, it is possible to program independent ailerons, flaps, retractable landing gear, multiple control surface positions or motor safety functions.

For an RC glider, EdgeTX allows pilots to configure flight modes, elevator compensation, butterfly functions and curves specific to different aerodynamic configurations.

Complex models can also use logical switches, timers and special functions to automate certain operations.

Organising model memories and settings

HELLORADIO transmitters allow users to store multiple model configurations.

Each model memory can contain channel settings, mixes, curves, alarms and telemetry parameters.

Models can be organised into categories such as aircraft, gliders, helicopters or drones.

The ability to associate an image and a checklist with each memory makes it easier to identify the correct model before use.

A model creation wizard also allows users to prepare an initial configuration based on the aircraft type, number of servos or installed functions.

The settings can then be freely modified.

Using EdgeTX Companion on a computer

The free EdgeTX Companion software, available for Windows, macOS and Linux, allows pilots to prepare and back up transmitter configurations from a computer.

It is particularly useful for creating model memories, checking certain mixes, making backups or restoring a configuration after a software operation.

This option is valuable for pilots using several RC models or wishing to keep a copy of their settings.

EdgeTX updates also provide access to corrections and improvements compatible with the hardware.

Users should follow the procedures specified for each transmitter and keep a backup before making any significant changes.

Gimbal precision and HELLORADIO transmitter ergonomics

Hall and RDC90 sensors: what are the differences for RC flying?

Radio transmitter control sticks, also known as gimbals, determine how accurately the pilot's movements are measured and transmitted to the electronic system.

The Hall sensors fitted to the V15 Standard, V15 MAX, V16 PRO and V16 MAX use a magnetic measurement principle without direct electrical contact at the position sensor.

This technology reduces certain types of wear associated with mechanical potentiometers, although springs, bearings and other moving components may still require maintenance.

The V15 ULTRA uses RDC90 sensors combined with CNC aluminium gimbals.

This version is intended for users looking for this particular measurement technology.

Regardless of the system chosen, control quality also depends on gimbal mechanics, adjustment, calibration and control programming.

Adjusting controls to suit your flying habits

HELLORADIO transmitters offer various adjustments to adapt the gimbals to the pilot, including centring force, throttle resistance, stick height and control mode.

Mode 1 and Mode 2 refer to different arrangements of the main controls on the sticks.

In Mode 1, the throttle is generally located on the right stick, whereas in Mode 2 it is located on the left stick.

The choice depends on the pilot's habits, training and the mode used at their aeromodelling club.

V16 transmitters are available in different Mode 1 or Mode 2 configurations.

It is important to select the correct product reference when purchasing.

Telemetry, diagnostics and safety for radio-controlled models

Monitoring flight information through telemetry

Telemetry allows an RC transmitter to receive information from the radio-controlled model when the receiver and required sensors are compatible.

Depending on the installation, the pilot can monitor receiver voltage, altitude, speed, GPS position, temperature, electrical consumption and radio link quality parameters.

HELLORADIO transmitters running EdgeTX allow users to customise how this information is displayed and create audible or vibration alerts.

On a glider, altitude or variometer announcements can help the pilot monitor the aircraft's flight without taking their eyes off it.

On an electric RC aircraft, a voltage or consumed-capacity alert can help manage flight duration, provided correctly installed and calibrated sensors are used.

HRS TOOLS: diagnostic tools integrated into the V15 transmitters

HELLORADIO V15 transmitters feature the HRS TOOLS system, which combines several measurement and diagnostic functions accessible directly from the transmitter.

These include servo and ESC testers, battery checking functions and an RC signal analyser.

The system can analyse different signal formats, including PWM, PPM, SBUS, CRSF, SUMD, DJI RS and MAVLink, depending on the functions used.

An integrated oscilloscope also allows users to observe the shape of certain signals and identify potential abnormalities.

These tools are particularly useful when installing a receiver, checking a servo or investigating wiring and configuration problems.

For RC enthusiasts maintaining several aircraft or helicopters, they can reduce the need for certain external measuring devices, although they do not replace every specialised diagnostic instrument.

Protection functions and pre-flight checks

HELLORADIO transmitters include electronic monitoring functions designed to check their power supply and circuit consumption.

The V16 models incorporate current and voltage measurement devices for monitoring various internal components.

EdgeTX software functions also allow pilots to create startup safety checks, switch position warnings and customised alarms.

These features complement essential pre-flight inspections: control linkage security, control surface direction, battery levels, motor operation and range testing.

For a large RC aircraft or a model equipped with numerous servos, a properly sized power supply and suitable failsafe settings remain essential.

Voice commands and advanced HELLORADIO transmitter functions

Voice commands on V16 RC transmitters

The HELLORADIO V16 PRO and V16 MAX feature voice recognition with 26 announced commands in English.

This functionality allows users to interact with certain transmitter functions without always using the screen or physical switches.

Depending on the programming, voice commands can be used to trigger an action, navigate certain functions or make adjustments supported by the system.

However, pilots must check that each command works correctly before use and retain the ability to regain manual control.

Voice telemetry announcements, also available on the V15 models, are a different function: they provide information to the pilot without necessarily recognising their voice.

Motion Control: controlling your model by tilting the transmitter

The V16 models incorporate motion sensors that allow transmitter tilt to be used as a control input.

This feature, known as Motion Control, can be assigned to certain axes or specific actions through programming.

It can be useful for experimenting with new control methods or triggering an auxiliary function without operating a switch.

However, it requires settings suited to the model and preliminary testing under safe conditions.

Gyroscopic functions on the V15 transmitters

The V15 models feature a gyroscope and accelerometer, allowing transmitter movements to be used in programming.

For example, tilting the transmitter can be assigned to a command or used to trigger a telemetry announcement.

A pilot can program the transmitter to announce the model battery voltage when the radio is deliberately tilted in a specified direction.

This provides an additional customisation option without making it necessary for conventional flying.

Battery life, charging and use in the field

What is the battery life of the HELLORADIO V15 and V16?

RC transmitter battery life mainly depends on battery capacity, RF module output power, screen brightness and enabled functions.

The V15 models offer a claimed operating time of up to 10 hours with an optional 5,000 mAh HELLORADIO battery, depending on settings.

For the V16 models, an indicative operating time of 10 to 30 hours is announced with a 5,000 mAh battery, depending particularly on the electronic configuration and radio module used.

These figures do not represent guaranteed battery life under all operating conditions.

The transmitters feature USB-C charging solutions and battery management systems.

A power supply compatible with the specifications of each model should be used.

For the V16 PRO and V16 MAX 4-in-1 references presented here, the battery and receiver must be purchased separately.

Trainer functions, simulators and flight training

HELLORADIO transmitters offer trainer functions that allow a master transmitter and a student transmitter to be used with a suitable connection.

This feature is useful when learning to fly RC aircraft, particularly when an instructor needs to be able to regain control quickly.

Depending on the version, the available functions allow certain channels to be assigned to the student and their operation to be adjusted.

USB-C connections intended for computer communication also allow the use of compatible flight simulators.

A simulator is particularly useful for learning control coordination, practising landing approaches and testing certain configurations before flying a real model.

HELLORADIO, Futaba or RadioMaster: how to choose your RC transmitter?

Beyond their advanced technical features, one of the main advantages of HELLORADIOSKY transmitters is their particularly competitive value for money: they offer many functions found on high-end RC transmitters from established brands such as Futaba, while generally being priced considerably lower than their Japanese and European counterparts.

RC enthusiasts looking for a high-end transmitter frequently compare HELLORADIO with brands such as Futaba, RadioMaster, Jeti, Spektrum and Graupner.

These manufacturers take different approaches to programming, protocols, ergonomics and receiver ecosystems.

HELLORADIO vs Futaba: open programming or a manufacturer-specific ecosystem

Futaba transmitters generally use programming systems and protocols specific to their product ranges.

HELLORADIO transmitters are based on EdgeTX, which provides open and customisable programming.

A HELLORADIO 4-in-1 transmitter may support certain compatible Futaba SFHSS receivers, but it cannot automatically replace a Futaba transmitter across all the manufacturer's protocols.

The choice depends particularly on existing receivers, required functions, the desired level of customisation and flying habits.

HELLORADIO vs RadioMaster: RC transmitters using EdgeTX

Both HELLORADIO and RadioMaster offer transmitters using EdgeTX and various transmission technologies, depending on the model.

Their differences should be assessed by comparing precise specifications: dimensions, switch layout, gimbal technology, integrated RF module, screen, battery and additional equipment.

The HRS TOOLS functions of the V15 models, the RDC90 sensors of the V15 ULTRA and the voice recognition capabilities of the V16 models are among the features worth considering.

It is preferable to compare two models with similar prices and configurations rather than draw a general conclusion about the manufacturers' entire ranges.
