ELRS Radio Transmitters
ELRS (ExpressLRS) is the open-source radio link most FPV pilots now fly, known for long range, low latency and inexpensive receivers. The radios on this page, from our Radio Transmitters range, have an ELRS module built in, so they bind to any ELRS receiver on the same band without an add-on module. Two choices shape the right radio: form factor, from compact gamepad-style radios to full-size trays, and frequency, since most run 2.4GHz while dual-band models add 868/915MHz. Gimbals and screen come next.
How to choose an ELRS radio
- Size: compact radios such as the RadioMaster Pocket, Pocket Crush and Zorro travel well and suit whoops and freestyle; the Boxer, TX12 MKII and TX15 add switches and a fuller grip; the TX16S family is the full-size option with a colour touchscreen and the most controls.
- Gimbals: hall-effect gimbals, used across most of this range, don't wear out like potentiometer gimbals. M2 gimbals are RadioMaster's newer hall-effect design.
- Frequency: 2.4GHz suits freestyle and racing with small antennas and high packet rates. Dual-band models such as the GX12 Gemini-X and TX16S MK3 Max Dual-Band add 868/915MHz, which carries further through obstacles; check the frequency rules that apply where you fly.
- Software: most models run EdgeTX, and the AX12 adds an Android interface.
What we stock
The range is built around RadioMaster: the Pocket and Pocket Crush, T8L, Zorro, TX12 MKII, Boxer, Boxer Crush and Boxer Max, TX15 Crush and TX15 Max, GX12 Crush and GX12 Dual-Band Gemini-X, the TX16S MKII in Hall V4.0, Max and transparent editions, the TX16S MK3 and MK3 Max Dual-Band, and the AX12. The TX12 MKII is also listed in a CC2500 version for pilots with FrSky receivers.
Compatibility
An ELRS radio binds to any ELRS receiver on the same band, 2.4GHz to 2.4GHz or 900MHz to 900MHz, using a bind phrase or the bind button. Keep the radio's ELRS module and your receivers on the same major firmware version (3.x with 3.x) or they won't link.
On the drone, wire the receiver to a spare UART and set the receiver protocol to CRSF in Betaflight, INAV or ArduPilot. ELRS receivers are small enough for whoops and cheap enough to leave one in every quad, so a single radio can fly your whole fleet.
Frequently asked questions
- Do I need an external module with these radios?
- No, each has ELRS built in. The module bay on larger radios can still take another protocol's module, such as Crossfire, if you fly a mixed fleet.
- Should I choose 2.4GHz or 900MHz ELRS?
- 2.4GHz suits freestyle and racing, with small antennas and high packet rates. 868/915MHz offers more range and better penetration for long-range flying, and dual-band radios cover both.
- Will an ELRS radio work with my Crossfire or FrSky receiver?
- Not through the built-in ELRS module, which talks only to ELRS receivers. Fit a matching external module, or switch the drone to an ELRS receiver.
