Radiomaster TX16S Mark III Max: A Legacy Refined!

Three days ago, when the first official teaser confirmed the release of the Radiomaster TX16S Mark III series, many pilots feared it would be more compact and offer fewer controls. However, Radiomaster chose to continue the legacy, focusing on refining the original design and further enhancing its versatility. In this review, we will focus on what’s new, what’s worth it, what could be done better, and the differences between the Standard and MAX editions.

The Radiomaster TX16S Mark III was released in two editions. While both offer the same features and deliver identical radio performance, the TX16S Mark III MAX comes with a premium carbon–fiber–style finish and top-notch AG02 CNC Hall sensor gimbals, as opposed to the budget V6 Hall sensor gimbals. While the MAX is available in four color schemes (Black / Red / Blue / Gold), the Standard edition offers two color options (Black / Transparent Charcoal).

The third-generation TX16S is built around the high-performance STM32H7 chipset and features a built-in dual-band ELRS Gemini-X radio system, supporting both 2.4 GHz and Sub-GHz 900 MHz operations. The radio unit is paired with a foldable antenna, contributing to a clean design while maintaining reliable signal performance.

Radiomaster TX16S MK3 Max review

Disclosure: I received this full-size ELRS radio controller from RadioMaster for testing and writing an in-depth review. Although the RC was offered for free, all opinions in this article remain my own, with no influence from my partner. I can’t guarantee you will get the same radio, as I received a pre-release unit.

RadioMaster has established itself as one of the most influential brands in the RC and FPV industry, consistently delivering feature-rich and pilot-focused products at competitive prices. Over the years, we have reviewed many of their products, including transmitters and receivers, and have seen a steady evolution in build quality, reliability, and innovation. The TX16S, in particular, has become an iconic radio controller, widely adopted by both hobbyists and professional pilots. Its versatility has made it a favorite among well-known FPV pilots such as Mr Steele, JohnnyFPV, and other prominent freestyle and cinematic creators.

The TX16S Mark III MAX comes in a well-designed carrying bag that provides excellent protection during transportation and storage. The kit includes two shoulder panels for future upgrades, spare tension springs and screws, a USB charging/data cable, a 2×18650 battery tray, a neck strap (lanyard), a screen protector, a bunch of radio stickers, and a user manual. Additionally, a pair of 18650 Li-ion batteries was included.

At a glance

Out of the four available color schemes, I received the red version—and I’ll admit, it immediately made an impression. I know a radio doesn’t have to be good-looking to perform well, but RadioMaster absolutely nailed it this time. Holding it in my hands felt less like a transmitter and more like a premium retirement gift… except this one doesn’t sit on a shelf—you take it out flying, and you enjoy every minute of it.

The Mark 3 follows the form factor and control layout of its predecessor. The radio measures 200 x 178 x 88mm and weighs about 860 grams without batteries. By comparison, the older Mark II measures 287 x 129 x 184mm and weighs 750 grams.

It features a carbon-fiber–style finish complemented by a leather-like insert on the grips, which immediately gives the transmitter a refined, premium look and feel. The textured materials not only enhance aesthetics but also improve grip and comfort during longer flying sessions. Subtle details, such as the decorative red stitching, further reinforce the high-end design language, adding a motorsport-inspired accent that elevates the overall visual appeal—even if the stitching itself is purely cosmetic.

As you can see in the photo above, most of the controls—including the AG02 CNC Hall sensor gimbals—are Ferrari red. To the left of the 5-inch, 800 × 480 IPS screen are the usual configuration buttons (SYS, RTN, PAGE >, PAGE <, and TELE), while the right side features a large scroll dial, all made from CNC-machined aluminum. The transmitter also includes six backlit configurable push buttons, similar to those found on the RadioMaster TX15.

It features three shoulder switches in each corner and a rear-mounted slider. The kit also includes an upgrade panel for users who want to install different switch types—a nice addition. Both front rotary dials and the rear slider have center detents.

On top of the radio, behind a rubber flap, there is a DSC trainer port, a USB port, and a 3.5 mm headphone jack. The multi-purpose USB Type-C port allows you to charge the unit, perform software updates, and use the transmitter as a computer simulator controller.

RadioMaster TX16s Mark 3: ELRS inside & outside

As mentioned, the new TX16S Mark III series integrates a built-in 1 W dual-band ExpressLRS (ELRS) RF module, supporting both 2.4 GHz and sub-900 MHz frequency bands. The system is paired with a foldable T-type dual-band antenna, optimized for efficient radiation patterns across both bands. The transmitter supports up to 16 fully configurable channels, making it suitable for complex aircraft, long-range platforms, and advanced flight modes.

If you need a different radio protocol or a more powerful ELRS transmitter, the back of the radio features a micro TX expansion bay. The rear of the transmitter also includes a foldable handle, which can double as a stand for added convenience.

Mine arrived with EdgeTX pre-2.12.0 firmware (dated January 5, 2026), so it was fresh out of the digital womb—that unmistakable “first boot” feeling of a brand-new transmitter. Pilots who like options, the RadioMaster TX16S Mark III MAX is also fully compatible with OpenTX, giving you the freedom to choose your preferred firmware and workflow without compromise.

Most menus operate smoothly and intuitively through touchscreen controls, making navigation quick and straightforward. However, there are some exceptions. For instance, when using the ELRS Lua script, the touchscreen is not functional, and you must rely on the physical buttons to navigate and select options. While this is a minor limitation, it highlights the importance of having tactile controls alongside a touchscreen, ensuring that every feature remains fully accessible under all operating conditions.

Battery options

The TX16S MK3 can be powered from 6.6 – 8.4V DC and features a generous battery bay with a 2S socket inside. RadioMaster recommends using their 2S 7.4V 6200mAh LIPO battery or two 18650 or two 21700 Li-ion cells. Using standard cylindrical batteries, you will need a dedicated battery tray. Mine came with a 18650 battery holder.

The radio has a built-in circuit that supports both LIPO and Li-Ion batteries. The smart balance battery circuit maximizes power efficiency and longevity, ensuring better battery life.

Pricing, availability, and options

The price of the TX16S Mark III was revealed just one day before the official release. I was expecting it to be priced around $300, so I was pleasantly surprised to see it come in at $269.99, which is only $20 more than its predecessor. If you don’t need the premium gimbals and upgraded finish, the Standard edition is available for just $199.99. Right now, only the FCC version is available, but the LBT version will be released soon for the EU region. All versions have RGB LED rings around the sticks. A compatible 2S 6200mah battery on the RadioMaster website is $29.99, and a pair of 21700 5000mAh batteries is $16.99.

Extra functions

While navigating through the built-in APPS, I came across the RSS Model Locator. This provides a useful tool for finding crashed drones, as long as the battery remains connected and the receiver is still broadcasting. Its operation is somewhat similar to tracking radio-tagged wildlife, making it a practical and reliable way to recover lost models.

The TX16S Mark III MAX features a built-in microphone, though its intended purpose has not yet been revealed by RadioMaster. There is also the possibility of installing a GPS module inside the radio. Additionally, it includes a built-in gyroscope sensor, which allows you to trigger switches, control pan/tilt cameras, or activate telemetry callouts simply by tilting the transmitter.

TX16S MK3 Max vs TX16S MK3 Standard: What’s the Difference?

When RadioMaster contacted me, I had to choose between the standard and the MAX edition. The choice was an easy one—when you have the option to go all in, why settle for less? That’s why I chose the premium (MAX) version of the TX16 MK3. But if you need to pay $70 more, you’ll probably want to know exactly what you get for your money.

Except for the gimbals, the two versions share the same hardware (CPU, LCD, internal RF, and antenna) and provide the same features and performance.

The TX16S Mark III MAX features AG02 gimbals with a full CNC-machined metal construction, providing improved rigidity, smoother stick movement, and greater long-term durability. Their higher mechanical precision allows for finer control inputs, which is especially noticeable in freestyle and cinematic flying.

In contrast, the Standard edition’s V6 Hall sensor gimbals use a more traditional plastic housing with Hall sensors, offering reliable and accurate performance, but with slightly less refinement in feel and mechanical robustness compared to the AG02 units.
