The RadioMaster Pocket ELRS is a compact EdgeTX FPV radio with Hall-effect gimbals, an internal 2.4 GHz ExpressLRS system, up to 16 channels, and a Nano external module bay.
The RadioMaster Pocket ELRS is a compact EdgeTX radio for FPV pilots who want an affordable transmitter they can use with multiple 2.4 GHz ExpressLRS models. It combines Hall-effect gimbals, up to 16 channels, a folding antenna, removable stick ends, a backlit display, and a Nano external module bay in a controller that is easier to transport than a full-size radio.
Its biggest limitations are the smaller gimbals and controls, the EdgeTX and ExpressLRS learning curve, and the fact that batteries are not included. Buyers must also verify that the offer is the ELRS version and that its FCC or LBT region matches where it will be used.
Best for
FPV beginners, simulator users, travelers, tiny-whoop pilots, and experienced pilots wanting a compact secondary ELRS radio.
Not ideal for
Pilots who prefer full-size gimbals, a large color display, extensive physical controls, or a radio that requires almost no initial configuration.
Verify before buying
Confirm ELRS rather than CC2500, the correct FCC or LBT region, Mode 2 if desired, and the exact 18650 cells required by the current offer.

The Pocket provides the functions most FPV pilots need without the size or expense of a flagship radio. The folding antenna, removable stick ends, and included carrying pouch make it practical for a field bag or backpack. At the same time, it runs EdgeTX rather than a simplified proprietary operating system.
EdgeTX supports separate model profiles, channel mapping, rates, curves, logical switches, timers, telemetry, voice alerts, Lua tools, and extensive control assignment. Beginners do not need to configure everything immediately, but the platform leaves room to grow without replacing the radio as soon as basic skills improve.
The X5 Hall-effect gimbals are another meaningful advantage over entry-level radios that use traditional potentiometers. The Pocket also allows gimbal tension adjustments and physical conversion between Mode 1 and Mode 2. Most U.S. FPV pilots will want Mode 2, with throttle and yaw on the left stick.
Its internal ExpressLRS system is intended for models equipped with compatible 2.4 GHz ExpressLRS receivers. One transmitter can store profiles for multiple compatible drones, airplanes, helicopters, cars, boats, or other RC models. The radio controls the receiver and flight controller; it does not replace FPV goggles or determine the drone’s video system.
Do not confuse ELRS and CC2500. RadioMaster sells Pocket radios with different internal RF systems. This product record is for the 2.4 GHz ExpressLRS version. The CC2500 version targets a different collection of legacy RC protocols and is not equivalent to an internal ELRS radio.
A drone marked “ELRS” is not automatically ready to bind without verification. Confirm that its receiver operates at 2.4 GHz, check the installed ExpressLRS firmware, and determine whether it uses a binding phrase, traditional bind mode, or an SPI receiver configuration.
ExpressLRS documentation recommends using the same binding phrase on compatible devices when that method is selected. The transmitter and receiver must also use compatible firmware. If a receiver will not bind, check the RF version, regulatory domain, firmware generation, receiver type, model configuration, and binding method before assuming the radio is defective.
The Nano module bay provides another upgrade route. RadioMaster lists compatibility with its Nano-size modules and TBS Nano Crossfire or Nano Tracer modules. An external module can add another supported radio system, but it does not make every receiver or aircraft universally compatible.
Current retailer feedback commonly praises the Pocket’s compact size, functionality, value, and customization. Setup difficulty and battery compatibility receive more mixed feedback. Those patterns reinforce two practical recommendations: source the correct 18650 cells before the radio arrives, and expect to spend time learning EdgeTX and ExpressLRS configuration.
The current Amazon listing is sold by a third-party seller and uses “Black” in its color selection, while RadioMaster calls the standard dark case “Charcoal.” Verify the seller, color, internal RF version, regulatory region, included accessories, and return policy on the exact offer.
The supplied package is a transmitter, not a complete FPV system. Goggles, drone, receiver, flight batteries, and model-specific charging equipment must be purchased separately unless they are already owned.
Use the product page for the purchase decision and the guides below for deeper research.
Long-range FPV drones do not have one dependable maximum distance. Usable range ends at the first limit reached by the control link, video link, battery reserve, navigation setup, terrain, interference, or flight rules.
An FPV drone build kit can mean a complete ready-to-fly package, a nearly finished drone that needs compatible equipment, or a loose collection of parts that still leaves major decisions to the buyer.
The RadioMaster Pocket ELRS is a strong value for pilots who want a compact EdgeTX transmitter with Hall-effect gimbals and a built-in 2.4 GHz ExpressLRS system. It can serve as a first serious FPV radio, a portable simulator controller, or a smaller backup transmitter for an existing ELRS fleet.
Its low entry cost does not remove the need to understand versions and compatibility. Buy it when portability, ELRS, customization, and value matter more than full-size ergonomics or a large display. Before ordering, verify the regional version and source the correct 18650 cells.
It works with appropriately configured models using compatible 2.4 GHz ExpressLRS receivers. Receiver frequency, firmware, binding method, model configuration, and regulatory domain must match. It does not control every drone simply because the drone uses the term FPV.
No. RadioMaster specifies two 3.7 V 18650 lithium-ion cells. The current retailer listing specifies flat-top cells. Verify the exact cell requirements and polarity before installation, and never force a cell that does not fit correctly.
Yes, the Pocket can be connected to a computer as a controller for compatible simulators. Use a USB data cable and select the appropriate USB joystick option when prompted by EdgeTX. Simulator calibration and channel mapping are normally required.
The ELRS version has an internal 2.4 GHz ExpressLRS transmitter. The CC2500 version supports a selection of CC2500-based protocols. Choose according to the receivers you intend to control rather than assuming one version includes both internal systems.
Yes. It has a Nano-size module bay that RadioMaster lists as compatible with its Nano modules and TBS Nano Crossfire or Nano Tracer modules. Verify the module’s physical fit, power requirements, firmware, and receiver compatibility.
Yes. RadioMaster provides rear gimbal adjustments for changing the throttle self-centering configuration and stick tension. Follow the official instructions carefully and update the EdgeTX control mode to match the physical configuration.

A binding phrase is usually the cleanest approach for managing several personal ELRS models. The same phrase must be configured on the transmitter module and receiver. Do not publish, share, or use an easily guessed binding phrase.
Traditional bind mode can also be started through the ExpressLRS Lua tool and the receiver’s supported bind procedure. Some receivers enter bind mode after repeated power cycles, while others use a button, web interface, Betaflight command, or model-specific process. Follow the receiver manufacturer’s instructions.
EdgeTX and ExpressLRS menus can change between releases. Use the current ExpressLRS RadioMaster internal-transmitter documentation when updating or troubleshooting the radio.

|---|---|---|
| ELRS | Internal 2.4 GHz ExpressLRS transmitter | Receiver frequency, firmware compatibility, and binding configuration |
| CC2500 | Internal CC2500 multiprotocol transmitter | The exact receiver protocol appears on the current supported-protocol list |
| FCC | Regional configuration intended for markets using the applicable FCC domain | That this is the correct legal configuration for the operating location |
| LBT | European Listen Before Talk regional configuration | That the receiver and transmitter use compatible regulatory-domain firmware |
The Pocket uses two 3.7 V 18650 lithium-ion cells, which are not included. The current Amazon offer specifies flat-top cells. Confirm the exact length, chemistry, voltage, polarity, and protection style before installation.
The radio provides built-in USB-C charging. The official manual states that the charging circuit is intended for two compatible 3.7 V lithium-ion cells with a maximum charging voltage of 4.2 V per cell.
The supplied Amazon listing identifies an ELRS, Mode 2 radio and states that batteries are not included. It is sold by STARDRONE rather than directly by RadioMaster. Verify the selected color, seller, ELRS version, FCC or LBT region, package contents, and return policy before ordering.
