Construct High quality and Ergonomics

Proper out of the field, the RadioMaster TX15 feels premium.

Left: TX15; Proper: TX16S

Whereas it shares an analogous format and kind issue with the Boxer—particularly in dimension, weight, and change positions—the TX15 isn’t only a Boxer with a coloration display. It introduces refined however significant upgrades in ergonomics and design that make an actual distinction.

For the Max model, the radio is available in a carbon fiber-look faceplate (notice: it’s painted plastic, not actual carbon fiber). There are three gimbal coloration 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 practically each new radio launched up to now two years, the TX15 makes use of a foldable antenna, much like the one discovered on the RadioMaster Pocket. This design is well-liked for its comfort, folding neatly for transport. Whereas some customers desire detachable antennas just like the Boxer as a result of it permits you to improve to greater acquire antennas, ExpressLRS has turn into so dependable and highly effective that the majority customers will discover the inventory 2dB antenna greater than sufficient. You can too rotate the antenna 90 levels for optimum alignment, which is a pleasant contact.

By way of weight and stability, the TX15 sits nearly completely degree on a neck strap (with two 18650 batteries). It might probably additionally stand upright on a flat floor by the best way.

It weighs roughly 790g together with 18650 batteries, inserting 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 case you do longer classes, I extremely suggest utilizing a neck strap.

As a result of the TX15 incorporates 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 if you end up pinching. Whereas this received’t have an effect on everybody, thumbers could discover the radio extra comfy to make use of than pinchers. Once more, a neck strap might help off load a few of the weight throughout lengthy flights.

Pinching and thumbing are two alternative 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 situated on prime 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 could require stick calibration the primary time.

There’s a material deal with on the again, might be simply eliminated if you need.

One small disappointment: the TX15 doesn’t include a gimbal/change protector just like the Boxer does, and there’s no neck strap included within the field. For a $200 radio, I anticipated these primary 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 Person Interface

The TX15 incorporates a vibrant coloration touchscreen. Whereas it’s barely smaller than the display on the TX16S, it truly has a barely greater decision, which makes the picture seem sharper and crisper. It jogs my memory of a smartphone display—brilliant, responsive, and straightforward to learn even below daylight. The backlight brightness can also be adjustable relying on ambient gentle situations.

The menu button format is sort of equivalent 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.

Radiomaster Tx15 Max Radio Transmitter Color Touch Screen Display Menu Buttons

Being a touchscreen, it significantly simplifies menu navigation—particularly when utilizing the on-screen keyboard. Typing in mannequin names or making configurations is far quicker than utilizing the scroll wheel alone.

That mentioned, until you’re continuously tweaking settings or getting into information, I personally don’t discover coloration touchscreens important. My every day radios, just like the Boxer and T20S, use primary monochrome shows, which have served me nicely for the previous 4–5 years (and earlier than that I used to be already utilizing the TX16S with coloration touchscreen). These less complicated shows additionally eat much less energy—an necessary benefit for lengthy flying classes.

Nonetheless, coloration screens open the door to options that monochrome shows merely can’t supply—like working superior LUA scripts for cool issues like real-time navigation, customized telemetry layouts, or displaying customized mannequin pictures. There’s quite a bit you are able to do with a coloration display, and it’s a subject that most likely 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).

Radiomaster Tx15 Max Radio Transmitter Gimbal Ag02

The AG02 is a brand new model of the AG01 and value about $90 a pair when bought individually: https://oscarliang.com/product-4xb7. So you’re saving $30 by going with the Max Version in case you finally need to improve to the AG02 gimbals.

So, do you have to go for the AG02s? That relies on your wants and funds.

The usual Corridor sensor gimbals are completely tremendous for many customers. You’ll have an ideal expertise flying with them and they are going to be simply as dependable. However in case you’re in search of a premium contact and might justify the price, the AG02s supply a smoother and extra refined management really feel, particularly in comparison these gimbals aspect by aspect. It’s like driving a automotive: a funds automotive will get you from level A to B with out points, however driving a well-tuned, high-performance automotive is a extra gratifying expertise—in case you have the choice, why not deal with your self?

The AG02s supply in depth adjustability :

  • Spring stress changes
  • Stick journey changes for each axes

Many of the changes might be finished on the surface of the gimbals, no have to open the radio. And bear in mind, even in case you go together with the bottom mannequin now, you may all the time 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 in case 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.

Yet one more 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 primarily based in your preferences.

Switches and Controls

In case you’re already acquainted with the RadioMaster Boxer, transitioning to the TX15 will really feel seamless—the layouts are practically equivalent. That mentioned, there are a couple of notable enhancements.

On the entrance, all 4 prime switches are 3-position, which I believe is a superb design alternative. This affords better 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—ultimate for digicam tilt, pan management, or different analog changes.

On the shoulders, the left change is a latching button, and the fitting change is a momentary button. Each might be swapped out with conventional toggle switches—RadioMaster features a 2-position and a momentary change 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 nicely for multirotor pilots, however the means to reconfigure these shoulder switches is large individuals in search of totally different setups.

Moreover, there are six RGB-backlit buttons above the display. These are generally used for flight mode choice however are totally 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 case you’re a pincher with bigger fingers, there’s an opportunity you’ll unintentionally bump them mid-flight. I’ve had the identical challenge on the T20S and ended up relocating these switches elsewhere. Apparently, the Jumper T15 solved this by barely repositioning the highest switches towards the middle of the radio, which is likely to be 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 received’t be a difficulty, however in case 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 generally have between 3000mAh and 3500mAh capability.

You even have the choice to make use of RadioMaster’s 5000mah battery pack (21700 cells), however take into account—these are considerably heavier. Personally, I desire 18650s—they’re lighter which is healthier for weight stability, and a full cost is often greater than sufficient for a complete afternoon of flying.

Be aware: Batteries aren’t included. You should use each button prime and flat prime cells. I like to recommend RadioMaster’s personal 18650 3200mAh cells: https://oscarliang.com/product-ykiv

I’ve examined them and located the efficiency strong: https://oscarliang.com/best-18650-li-ion-battery/#Outcomes-and-Suggestions

Charging is straightforward: simply plug a USB-C cable into the port on prime. It requires a 5V energy supply, and attracts as much as 2A (charging energy peaks round 10W). Absolutely charging depleted 3200mAh batteries takes roughly 3 hours.

Energy Consumption & Battery Life

Listed here are my measurements of the TX15’s present draw (display brightness at minimal until said in any other case). Voltage enter: 7.4V.

  • RF module off: 0.3A
  • RF module off, display at max brightness: 0.42A

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 incorporates a highly effective H7-based processor, which delivers smoother menu navigation, quicker LUA script execution, and better 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 to date. For comparability, its closest rival—the Jumper T15—affords solely 2GB (with 1.3GB usable). This further reminiscence provides you far 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 giant media information or backups. Be aware, nevertheless, that inserting a microSD card disables the onboard flash reminiscence—you may’t use each on the similar time. That mentioned, most customers most likely received’t run out of the interior house.

Out of the field, the TX15 ships with EdgeTX model 3.0.0, so that you’re totally able to reap the benefits of probably the most present options .

RF Module: ExpressLRS

The interior 1W ExpressLRS RF module helps twin band 2.4GHz and 900MHz frequency bands (you should use one frequency, however not concurrently). You’ll be able to change between them by way of the ExpressLRS LUA script, offered your receiver additionally helps the chosen frequency. This provides the TX15 glorious versatility, particularly for pilots who need to fly all the pieces from micro drones to long-range rigs. The RF module comes with ELRS V3.5.5 out of the field.

That mentioned, 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.
