The Bandit Says 915MHz. UK Pilots Must Read This First
Quick Answer
The RadioMaster Bandit Micro is a single-band 900MHz ExpressLRS module, despite the 915MHz name. In the UK, flash the transmitter and receiver for the EU 868 domain before use, keep airborne output within current Ofcom limits, and pair it with a 900MHz receiver. For most freestyle pilots, we would still buy 2.4GHz.
The 915MHz Label Is a Configuration Warning
Our current RadioMaster Bandit Micro listing describes hardware built around an SX1276 radio, with 25–200Hz packet rates, up to 1W hardware output, a TCXO, OLED controls and a Micro/JR-style five-pin bay. It weighs 78g with its T antenna and also accepts 6–16.8V through XT30.
The important UK detail is not the headline wattage. RadioMaster identifies the factory regulatory domain as FCC915, while ExpressLRS provides a separate EU_868 build option. UK pilots must compile or select the EU 868 regulatory domain on both ends of the link; FCC915 settings are not a UK shortcut.
Ofcom’s current IR2030 conditions allow relevant non-specific short-range equipment to be used airborne in parts of 868MHz at no more than 25mW e.r.p., with spectrum-access or duty-cycle conditions. Current ExpressLRS documentation says its EU regulatory domains use listen-before-talk. We would therefore cap this airborne setup at 25mW and leave the advertised 1W capability alone. Selecting EU_868 changes the frequency plan; it does not turn maximum hardware power into permission.
What It Will—and Will Not—Bind To
The Bandit is not a 2.4GHz module and not a Gemini X module. ExpressLRS compatibility starts with band matching: a 900MHz transmitter works with 900MHz receivers when their major firmware, binding phrase and regulatory domain also match. Our Happymodel ES900 Dual Diversity receiver is the logical UK pairing: it is explicitly specified for 868MHz, uses two SX1276 RF chains and weighs 1.5g without antennas.
A normal 2.4GHz receiver will not bind to the Bandit. Nor does fitting one Bandit antenna create cross-band redundancy. If you want simultaneous 2.4GHz and sub-GHz packets, read our Gemini X setup guide; that needs dual-band LR1121 hardware at both ends.
Bandit or Ranger Micro?
For racing, whoops and ordinary five-inch freestyle, we would choose the RadioMaster Ranger Micro 2.4GHz module. It fits the same class of radio bay, supports packet rates up to F1000, and its smaller receiver antennas are easier to mount cleanly. Our Ranger module comparison explains why bay format matters more than the case.
Choose the Bandit when the aircraft has room for longer 868MHz antennas and the mission genuinely benefits from sub-GHz propagation, such as a large fixed-wing or carefully planned long-range build. Do not buy it merely because “1W” sounds safer. Correct antenna placement, legal power, packet rate and a clean installation matter more than the largest number on the box. Browse our verified radio controllers and receivers if 2.4GHz or dual-band hardware better fits the aircraft.
FAQ
Q: Can the 915MHz Bandit Micro be used in the UK?
A: The hardware can operate on 868MHz, but it must be flashed for the correct EU_868 domain and used within current UK spectrum conditions. Do not transmit with its factory FCC915 configuration.
Q: Can Bandit bind to a 2.4GHz ELRS receiver?
A: No. The Bandit Micro uses 900MHz-class SX1276 hardware. Use a compatible 868/900MHz receiver with matching firmware and domain settings.
Q: Is Bandit better than Ranger Micro?
A: Not for most FPV builds. Ranger Micro offers faster 2.4GHz packet rates and easier antenna installation. Bandit earns its place on larger aircraft where sub-GHz propagation is worth the extra antenna size and configuration care.
