2026 has been a busy year for RadioMaster! In January they launched their new flagship, the TX16S Mk3. And now, barely six months later, they've released another high end radio, the GX15.
Why two high end radios? According to RadioMaster, the new radio is optimised for LoS (line-of-sight) applications like planes, helis and gliders. Having tested it - including sessions with an F3F model - I can see why.

Over the last two decades I've reviewed many radios, but only four have been at my side at F3F glider racing events. My current unit is the RadioMaster TX16S Mk1 - it's served me faithfully for five years and 30 competitions. It seems I’m not alone in really liking this radio, as the TX16S has been a huge hit for RadioMaster.
Times change, though, and the design is starting to show its age. While the Mk2 has some useful refinements over the Mk1, they both struggle with recent versions of EdgeTX. (This, by the way, is why I'm still running OpenTX).
Enter the TX16S Mk3, RadioMaster's new flagship radio. With its H7 processor and Gemini RF module it promises a more agile EdgeTX experience, as well as advanced support for ELRS.
So, how well does it fulfil its promise? What about important aspects, like ergonomics? Read on and find out!
Since their beginnings just five years ago, RadioMaster have built an enviable reputation for their well designed and reasonably priced transmitters.
The TX15 is their latest unit - and rather interesting it is, too. Marrying a fast STM32 H7 processor with the latest EdgeTX 3.0, the TX15 provides a glimpse into the future of open source RC.
In this review, I'll explore the TX15’s features and take it for a test flight with an F3F sailplane. So read on!

The Radiomaster Pocket is a wonderfully versatile little transmitter - it can be used for anything from cheap foamies to high-value moulded models.
If it has a weakness, it's the rather ordinary gimbals - with their all plastic construction, they lack the precision feel of the AG01 CNC gimbals which I have come to love on the TX16S.
Well, it seems that Radiomaster have an answer to this: a CNC gimbal specifically designed for the Pocket. They've called it the AG01 Nano. (Not to be confused with the AG01 Mini, which targets the Zorro and TX12.)

How times change! FrSky, once champions of open source, now have their own proprietary operating system called Ethos. Their range of transmitters has grown, too, split between the Tandem (2.4GHz/900MHz) and Twin (2x2.4GHz) families.
The TX14S is one of their more recent radios. With compact dimensions and Twin support, the TX14S appears to be a good choice for soaring and electric flight. So, when FrSky offered me a unit to review I needed no persuading.

After a few weeks with the unit, has the X14S lived up to expectations? Read on and find out!

Once in a while a transmitter comes along which is different and interesting, and it’s this kind of radio that I love to review.
Enter the Radiomaster GX12 - small in size yet with several novel features, including gimbals with 3D Hall sensors, and support for Gemini transmission modes.
But just how good is the GX12 for sailplane and electric applications? And what are the benefits, if any, of Gemini? Read on and find out!
It's hard to believe that ten years have passed since I created OpenTX Clinic!
At the time, FrSky had just launched the Taranis X9D with a novel operating system called Open9X soon to be renamed OpenTX. Since then both OpenTX and its offspring EdgeTX have exploded in popularity, and the website has expanded with tutorials, templates and Lua scripts.
