RadioMaster dropped a bombshell last year with their brand new, compact, full-size radio control system called the BOXER. This bad boy follows in the footsteps of its predecessors, the TX16S and TX12S, but with some great upgrades. It comes in three versions: CC2500 multi-protocol, 4-in-1 multi-protocol, and ELRS 2.4GHz protocol.
Here’s where things get really interesting. The BOXER’s ELRS protocol is a game changer. You can easily upgrade it over Wifi and tweak all those sweet parameters to your heart’s content. Talk about user friendly, right? No wonder it’s becoming the FPV radio protocol of choice for all the cool pilots.
Well, it’s been six months since I got my hands on this beauty, and it’s time to spill the beans on its performance. Get ready for a deep dive into the BOXER’s features, reliability, and overall awesomeness. Let the review begin!

EdgeTX Operating System
The system comes with the open-source EdgeTX system, featuring a sleek 128*64 monochrome LCD display powered by the STM32VGT6 chip.
But here’s the real kicker: the ELRS version takes things up a notch with its adjustable refresh rate, supporting an impressive F-1000Hz. And if you’re operating in FCC mode, you’ll be thrilled to know that you can crank the power up to a whopping 1W.
The RadioMaster BOXER has a unique shoulder button design that sets it apart. On the left, you’ll find the self-locking switch (SE button), while on the right, you’ll find the self-recovery switch (SF button).
This design may remind you of the TBS MAMBO, but the BOXER has its own distinctive details. In particular, it offers an ergonomically designed back index finger grip, a comfortable fabric grip, a spacious battery compartment, six convenient shortcut mode buttons and a removable T-antenna.
The package also includes a complimentary storage pouch and bumper for added convenience.
On the bottom, you’ll find a USB fast charge port that supports QC3.0 fast charging for fast and efficient charging. It can handle a maximum current of 2.0A for 2S batteries.
The expanded battery compartment provides ample room for a 6200mAh 2S battery, providing an impressive 20 hours of battery life as per the official specifications. Even with the additional RF head installed, battery life is not an issue, ensuring you have enough power for at least an afternoon of outdoor use.
It’s a good idea to have separate USB ports for charging and for the simulator. Prolonged charging to 100% can significantly reduce the life of a lithium battery. Using a simulator and charging from the same port can be a problem.
With the BOXER, however, you can charge the LiPo battery up to 90% and then use it for a sim game. Afterwards, you can simply turn off the TX without saving the charge or experiencing a noticeable reduction in maximum capacity over the next few weeks.
Hall Effect Gimbals
The Boxer radio control is equipped with V4.0 Hall Effect gimbals, which eliminate potentiometers and instead use magnetic sensors for greater precision. The AG01 gimbal, machined from high-quality CNC metal, offers superior precision and smooth return compared to the V4.0 Hall Effect gimbal.
For those who prefer the AG01 gimbal, it is also available as an optional upgrade at an additional cost.
-The Boxer has much better ergonomics than the TX16.
-The Boxer radio’s internal Express LRS module exceeds the 250 mW of power found in the TX16S. It also has built-in cooling to ensure optimal performance even as the module heats up.
-The screen of the Boxer is not as good as the screen of the TX16.
-The top button on the outer edge of the RadioMaster Boxer radio feels a little rough and scratchy.
I think the Boxer radio is going to be a big hit with a lot of people. It’s a feature-packed radio with multiple switch controls and functions, all in a compact size. Whether you choose the ELRS, 4-in-1, or CC2500 module, it’s got you covered for whatever you want to use. The ergonomics are even better than the TX16s, with a comfortable fit for your fingers on the radio.
Now, there are a few minor gripes that some people have mentioned, like the screen not being as large as the TX16’s and the top buttons feeling a little scratchy. But honestly, these are just minor nitpicks in an otherwise great experience. Overall, this remote is definitely worth your time.
