At first look, the brand new RadioMaster TX15 may appear like a color-screen model of the beloved Boxer, however don’t be fooled—it’s rather more than that. After hands-on testing, I discovered the TX15 to be a thoughtfully engineered transmitter, filled with sensible options that make it some of the forward-thinking EdgeTX radios so far.
From highly effective internals and ergonomic design to quality-of-life enhancements and customization choices, the TX15 goals to serve a variety of pilots—from informal FPV fans to superior fixed-wing and glider flyers. On this assessment, I’ll stroll you thru my expertise with the TX15, what makes it stand out, and who it’s finest suited to.

Construct High quality and Ergonomics
Proper out of the field, the RadioMaster TX15 feels premium.
Left: TX15; Proper: TX16S
Whereas it shares an identical format and kind issue with the Boxer—particularly in dimension, weight, and swap positions—the TX15 isn’t only a Boxer with a colour display. It introduces refined however significant upgrades in ergonomics and design that make an actual distinction.
Left: TX15; Proper: Boxer
The grips are properly contoured and textured, providing a agency, safe maintain. Whereas the Boxer was already a well-regarded radio, the TX15 refines that formulation with improved hand really feel and higher stability.
Left: TX16S; Center: TX15; Proper: Boxer
For the Max model, the radio is available in a carbon fiber-look faceplate (observe: it’s painted plastic, not actual carbon fiber). There are three gimbal colour choices—purple, gold, and black—unique to the AG02 CNC gimbals. I opted for purple gimbals, and so they look implausible in opposition to the carbon-fiber face.
Like almost each new radio launched up to now two years, the TX15 makes use of a foldable antenna, just like the one discovered on the RadioMaster Pocket. This design is well-liked for its comfort, folding neatly for transport. Whereas some customers want detachable antennas just like the Boxer as a result of it lets you improve to greater acquire antennas, ExpressLRS has turn into so dependable and highly effective that almost all customers will discover the inventory 2dB antenna greater than satisfactory. You can even rotate the antenna 90 levels for optimum alignment, which is a pleasant contact.
When it comes to weight and stability, the TX15 sits virtually completely stage on a neck strap (with two 18650 batteries). It might additionally stand upright on a flat floor by the way in which.
It weighs roughly 790g together with 18650 batteries, putting it between the TX16S and the Boxer. For comparability, my every day driver, the T20S, weighs simply 540g, and I do discover elevated fatigue when flying the TX15 for prolonged intervals. In the event you do longer classes, I extremely suggest utilizing a neck strap.
As a result of the TX15 encompasses a bigger show, the decrease portion of the radio is barely prolonged to accommodate it. This makes the radio really feel a bit extra bottom-heavy in comparison with the Boxer, particularly when you’re pinching. Whereas this gained’t have an effect on everybody, thumbers could discover the radio extra comfy to make use of than pinchers. Once more, a neck strap will help off load a number of the weight throughout lengthy flights.
Pinching and thumbing are two other ways of holding the sticks, be taught extra right here: https://oscarliang.com/pinch-thumb-stick/
All ports—together with the USB-C, headphone jack and DSC coach port—are positioned on high of the radio. I’m particularly happy that RadioMaster has lastly merged the 2 USB-C ports (charging and simulator) right into a single, unified port. This simplifies setup when connecting to FPV simulators. The TX15 is appropriate with all main FPV sims together with Liftoff and Tryp, although it might require stick calibration the primary time.
There’s a cloth deal with on the again, might be simply eliminated if you would like.
One small disappointment: the TX15 doesn’t include a gimbal/swap protector just like the Boxer does, and there’s no neck strap included within the field. For a $200 radio, I anticipated these fundamental equipment to be a part of the bundle. Together with them would’ve added to the general worth.
On the underside, there are two threaded holes that seem to help attachments corresponding to a waist help or different equipment.
Show and Consumer Interface
The TX15 encompasses a vibrant colour touchscreen. Whereas it’s barely smaller than the display on the TX16S, it really has a barely greater decision, which makes the picture seem sharper and crisper. It jogs my memory of a smartphone display—vivid, responsive, and straightforward to learn even beneath daylight. The backlight brightness can be adjustable relying on ambient gentle situations.
The menu button format is almost similar to that of the Boxer and TX16S. The buttons are doubtless CNC-machined aluminum, providing a satisfying tactile click on and a concave floor that helps your fingers naturally settle into place.
Being a touchscreen, it vastly simplifies menu navigation—particularly when utilizing the on-screen keyboard. Typing in mannequin names or making configurations is far sooner than utilizing the scroll wheel alone.
That stated, except you’re always tweaking settings or getting into information, I personally don’t discover colour touchscreens important. My every day radios, just like the Boxer and T20S, use fundamental monochrome shows, which have served me properly for the previous 4–5 years (and earlier than that I used to be already utilizing the TX16S with colour touchscreen). These less complicated shows additionally eat much less energy—an necessary benefit for lengthy flying classes.
Nonetheless, colour screens open the door to options that monochrome shows merely can’t provide—like working superior LUA scripts for cool issues like real-time navigation, customized telemetry layouts, or displaying personalised mannequin pictures. There’s rather a lot you are able to do with a colour display, and it’s a subject that in all probability deserves its personal devoted article.
AG02 Gimbals
The TX15 Max Version I examined comes with AG02 gimbals, whereas the bottom mannequin options customary Corridor sensor gimbals (V5.0).
The AG02 is a brand new model of the AG01 and price about $90 a pair when bought individually: https://oscarliang.com/product-4xb7. So you’re saving $30 by going with the Max Version should you finally wish to improve to the AG02 gimbals.
So, do you have to go for the AG02s? That will depend on your wants and finances.
The usual Corridor sensor gimbals are completely superb for many customers. You’ll have an amazing expertise flying with them and they are going to be simply as dependable. However should you’re on the lookout for a premium contact and might justify the fee, the AG02s provide a smoother and extra refined management really feel, particularly in comparison these gimbals facet by facet. It’s like driving a automotive: a finances automotive will get you from level A to B with out points, however driving a well-tuned, high-performance automotive is a extra pleasant expertise—if in case you have the choice, why not deal with your self?
The AG02s provide intensive adjustability :
- Spring rigidity changes
- Stick journey changes for each axes
Many of the changes might be executed on the skin of the gimbals, no have to open the radio. And bear in mind, even should you go together with the bottom mannequin now, you may at all times improve to AG02 gimbals later—they’re plug-and-play appropriate with the TX15.
They use M4 threads for the stick ends, which is necessary to notice should you plan to make use of customized stick ends. Fortunately, the included Radiomaster’s Sticky360 stick ends are amongst my favorites, so I didn’t really feel the necessity to swap them out.
Another perk unique to the Max version: RGB gimbal lights. These customizable LED rings are mounted round every gimbal and might be configured by way of LUA scripts. By default, they present a rainbow sample, however you may change the colours or results based mostly in your preferences.
Switches and Controls
In the event you’re already aware of the RadioMaster Boxer, transitioning to the TX15 will really feel seamless—the layouts are almost similar. That stated, there are a couple of notable enhancements.
On the entrance, all 4 high switches are 3-position, which I believe is a wonderful design alternative. This affords higher flexibility for a wider vary of builds, together with mounted wings and planes. In direction of the center, you get two rotary dials with a middle detent—ideally suited for digicam tilt, pan management, or different analog changes.
On the shoulders, the left swap is a latching button, and the appropriate swap is a momentary button. Each might be swapped out with conventional toggle switches—RadioMaster features a 2-position and a momentary swap within the field, and 3-position switches can be found for buy: https://oscarliang.com/product-u472
The method is plug-and-play—no soldering required. Out of the field, this configuration works properly for multirotor pilots, however the means to reconfigure these shoulder switches is big individuals on the lookout for completely different setups.
Moreover, there are six RGB-backlit buttons above the display. These are generally used for flight mode choice however are absolutely customizable within the settings to fit your wants.
Small Ergonomic Quirk
One factor I did discover: the highest nook switches are a bit too near the gimbals. In the event you’re a pincher with bigger fingers, there’s an opportunity you’ll by chance bump them mid-flight. I’ve had the identical subject on the T20S and ended up relocating these switches some other place. Curiously, the Jumper T15 solved this by barely repositioning the highest switches towards the middle of the radio, which is perhaps a good suggestion for future revisions of the TX15.
No Sliders
Additionally value mentioning: there aren’t any sliders on the TX15. For many FPV pilots, this gained’t be a problem, however should you require analog sliders, simply pay attention to this limitation.
Battery and Charging
The TX15 comes with a battery tray within the rear compartment that holds two 18650 Li-ion cells which usually have between 3000mAh and 3500mAh capability.
You even have the choice to make use of RadioMaster’s 5000mah battery pack (21700 cells), however have in mind—these are considerably heavier. Personally, I want 18650s—they’re lighter which is healthier for weight stability, and a full cost is often greater than sufficient for an entire afternoon of flying.
Observe: Batteries aren’t included. You need to use each button high and flat high cells. I like to recommend RadioMaster’s personal 18650 3200mAh cells: https://oscarliang.com/product-ykiv
I’ve examined them and located the efficiency stable: https://oscarliang.com/best-18650-li-ion-battery/#Outcomes-and-Suggestions
Charging is easy: simply plug a USB-C cable into the port on high. It requires a 5V energy supply, and attracts as much as 2A (charging energy peaks round 10W). Totally charging depleted 3200mAh batteries takes roughly 3 hours.
Energy Consumption & Battery Life
Listed below are my measurements of the TX15’s present draw (display brightness at minimal except acknowledged in any other case). Voltage enter: 7.4V.
- RF module off: 0.3A
- RF module off, display at max brightness: 0.42A
- 10mW: 0.46A
- 25mW: 0.51A
- 50mW: 0.54A
- 100mW: 0.58A
- 250mW: 0.71A (cooling fan activated by default)
- 500mW: 0.82A
- 1000mW: 1.07A
- 1000mW with display at max brightness: 1.19A
Estimated Runtime (with 3200mAh battery):
- 10mW: Slightly below 7 hours
- 250mW: ~4.5 hours
- 1000mW: just below 3 hours
Radio Firmware: EdgeTX
That is the place the TX15 actually pulls forward of different radios in its class. It encompasses a highly effective H7-based processor, which delivers smoother menu navigation, sooner LUA script execution, and higher future-proofing as EdgeTX evolves with extra demanding options.
It additionally comes with 4GB of onboard reminiscence (3.6GB usable), the most important we’ve seen in any EdgeTX radio thus far. For comparability, its closest rival—the Jumper T15—affords solely 2GB (with 1.3GB usable). This further reminiscence provides you rather more room for mannequin pictures, sound packs, themes, and telemetry logs.
Though you don’t want an SD card, there’s nonetheless a microSD slot accessible that helps as much as 32GB FAT32 playing cards. That is particularly helpful if you wish to retailer massive media information or backups. Observe, nonetheless, that inserting a microSD card disables the onboard flash reminiscence—you may’t use each on the similar time. That stated, most customers in all probability gained’t run out of the interior area.
Out of the field, the TX15 ships with EdgeTX model 3.0.0, so that you’re absolutely able to make the most of probably the most present options .
RF Module: ExpressLRS
The inner 1W ExpressLRS RF module helps twin band 2.4GHz and 900MHz frequency bands (you should utilize one frequency, however not concurrently). You may swap between them by way of the ExpressLRS LUA script, supplied your receiver additionally helps the chosen frequency. This provides the TX15 wonderful versatility, particularly for pilots who wish to fly all the things from micro drones to long-range rigs. The RF module comes with ELRS V3.5.5 out of the field.
That stated, it doesn’t help Gemini XROSSBAND mode just like the Radiomaster GX12 does, which can disappoint critical long-range pilots who prioritize hyperlink redundancy and failover. If you wish to use this function you should purchase a Nomad module and set up it within the exterior RF module bay within the again.
However for many pilots—together with myself—that is hardly a limitation. I primarily fly on 2.4GHz, and I’ve efficiently flown out to over 10 kilometers with no points in any respect.
Radio Comparisons: GX12, Jumper T15
Some facet by facet comparability with the Radiomaster GX12 radio and Jumper T15.

- Missing swap/gimbal protector and neckstrap
Last Ideas
After spending a while flying with the Radiomaster TX15, I can confidently say it is a extremely succesful radio. It’s some of the full transmitters—filled with options, wonderful construct high quality, and considerate design updates. It affords all the things most FPV and RC pilots would ever want, whether or not you’re flying quads, mounted wings, or gliders. In reality, I believe it has absolutely changed the TX16S for me by way of day-to-day usability and have set. It’s future-proof, highly effective, and versatile.
That stated, in case your present radio is working properly for you, there’s no pressing have to improve—except you particularly need a big colour touchscreen or a number of the distinctive options the TX15 affords are important to your setup or flying type.
Purchase the TX15 Base Mannequin:
Purchase the TX15 Max Version:
Personally, I’ll nonetheless use the T20S for backpacking and journey as a result of its portability, whereas the Pocket stays the most effective worth radios for the budget-conscious pilots and newcomers. However for these on the lookout for a radio with a colour display, the TX15 is a high contender in 2025—it’s such a flexible radio and might achieve this a lot.
