RadioMaster makes two of the most popular radios in the FPV and hobby RC space: the Boxer and the TX16S. Both run EdgeTX firmware and both are available in ExpressLRS variants. On paper they serve the same market — but in practice they are built for meaningfully different use cases and pilot profiles.

The Boxer is a gamepad-style transmitter aimed squarely at FPV quad pilots who want portability and a familiar controller form factor. The TX16S is a full-size traditional transmitter designed for pilots who want expandability, more channels, and a home across both FPV and multi-rotor fixed-wing hobby RC. Choosing between them depends almost entirely on how you plan to fly and whether portability or expandability matters more.

Published Spec Comparison

Form Factor & Ergonomics

This is the most immediately obvious difference. The Boxer's gamepad-style grip means thumbs naturally wrap the controller the way they would a PlayStation or Xbox pad. Pilot reviews consistently describe it as more comfortable for extended FPV sessions than a traditional neck-strap transmitter, particularly for pilots who prefer thumb-flying style.

The TX16S uses the classic full-size tray-and-handle layout that has dominated RC for decades. It is heavier and larger, which most pilots find makes it better for desktop use and for flying larger multi-rotor or fixed-wing models where extended sessions are common. The weight (roughly double the Boxer's) makes it less convenient to carry casually but more stable resting on a surface.

Aggregated pilot feedback suggests that pure FPV freestyle pilots heavily prefer the Boxer for on-the-go flying; pilots who also fly planes, gliders, or larger octocopters default to the TX16S.

Gimbal Quality

Both the Boxer and TX16S use Hall-effect gimbals per RadioMaster's published specifications, which means no physical potentiometer contacts to wear out — gimbal signal is read magnetically. This is a significant upgrade over the budget radios new pilots often start with and is one of RadioMaster's main selling points across its lineup.

Pilot reviews for both models rate gimbal feel in the "smooth with minimal center slop" category for stock units. The TX16S is available in M1/M2 configuration (mode 1 or mode 2) and in Max variants with upgraded Hall-effect gimbals; the Boxer is also available in M1 and M2. Neither has a dominant gimbal quality advantage in published data — the difference comes down to throw length preferences, which pilots typically tune via EdgeTX's calibration tools.

Protocol and Module Support

Both radios run ExpressLRS internally in their ELRS variants, covering the dominant FPV protocol. The key difference is the external module bay.

The TX16S has a full JR-compatible external bay that accepts any JR-format or Nano (with adapter) module. This means you can add TBS Crossfire (full power), ELRS external modules, FrSky R9M, or other protocols without compromising the internal ELRS capability.

The Boxer has a Nano-size module bay only. While most modern ELRS and Crossfire Nano modules fit this bay, you cannot mount a full-size JR module. For pilots who need maximum protocol flexibility across older FrSky or Spektrum receivers, the TX16S's full JR bay is the safer long-term bet.

For pure ELRS FPV flying, neither limitation matters — the internal 2.4 GHz ELRS module covers essentially all current FPV receivers.

Channel Count

The Boxer provides 12 physical channels; the TX16S provides 16. For FPV freestyle and racing quads, 8–10 channels covers everything you will use (throttle, pitch, roll, yaw, arm, mode, beeper, VTX channel, etc.), so the Boxer's 12 channels is never a real limitation in the FPV context.

For fixed-wing flying with flaps, spoilers, rudder, elevator, multiple servo channels, and gear switches, 16 channels provides meaningful headroom. If there is any chance you will expand into fixed-wing or more complex multi-rotor rigs with external gimbal controls, the TX16S's extra channels are worth having.

Battery & Portability

Both radios run on 2× 18650 lithium cells, providing long run times (published estimates suggest 10–20+ hours per charge depending on backlight and RF output usage). The Boxer is dramatically lighter and smaller, making it easy to toss in a backpack without dedicated RC gear bags. The TX16S benefits from a neck strap or tray and is better suited to pilots who transport their gear in dedicated RC cases.

Which Should You Buy?

Buy the RadioMaster Boxer if:

• Your primary activity is freestyle or racing FPV quads.
• You prefer a compact, portable form factor that travels easily.
• You are a thumb flyer who finds a gamepad grip more natural.
• You do not need a full JR external module bay or 16 channels.

Buy the RadioMaster TX16S if:

• You fly — or plan to fly — fixed-wing models, gliders, or multi-rotor platforms needing 13+ channels.
• You want maximum external module flexibility including full-size JR modules.
• You prefer a traditional full-size transmitter with a neck strap for desktop flying.
• The MULTI-protocol internal module is important for compatibility with older receivers.

Bottom Line

Both radios are excellent EdgeTX platforms with Hall-effect gimbals and ELRS built in. The Boxer wins on portability and FPV ergonomics; the TX16S wins on expandability and versatility. For a pilot whose flying is 100% FPV freestyle quads, the Boxer is the cleaner, cheaper, and more practical choice. For pilots who want one radio to cover all RC disciplines now and in the future, the TX16S is the long-term investment.
