MORE INFORMATION
The RadioMaster AX12 Android Radio Controller redefines the future of FPV and UAV control systems by combining a professional RC transmitter with the power of Android computing. Designed for FPV pilots, autonomous drone operators, filmmakers, rover builders, and robotics developers, the AX12 delivers advanced functionality in a compact and ergonomic form factor.
Powered by Android 9.0 and RadioMaster OS, the AX12 allows pilots to run popular drone applications, including Betaflight Configurator, QGroundControl, DJI Fly, telemetry software, mapping tools, and simulator apps directly on the transmitter without needing an external tablet or laptop.
The bright 5.5-inch HD touchscreen with 1000 nits brightness ensures excellent outdoor visibility, while the integrated ExpressLRS RF system provides ultra-low latency and reliable long-range communication for FPV drones and UAV platforms.
With HDMI input and output support, the AX12 can display external FPV feeds directly on the controller and also transmit clean video output to monitors or recording systems, making it ideal for professional field operations, training environments, and cinematic workflows.
The transmitter features precision X5 Hall effect gimbals, removable stick ends, integrated 64GB storage, WiFi firmware updates, and support for external Nano RF modules, giving advanced users unmatched flexibility and expandability.
Whether you fly FPV drones, fixed-wing aircraft, rovers, boats, or autonomous UAV systems, the AX12 offers a complete smart ground control solution in a single device.
An octa-core processor, 4 GB of RAM, and 64 GB of storage deliver smooth performance for control tasks, telemetry viewing, supported ground station apps, and utilities. The 5.5-inch HD IPS touchscreen (1280 × 720) delivers sharp visuals and 1000 nits brightness for excellent visibility even in direct sunlight. The responsive touchscreen interface makes navigating menus and adjusting settings quick and intuitive in the field.
At its core, the AX12 remains a full- featured RadioMaster transmitter. It supports full 16-channel ExpressLRS control with advanced mixing, arbitrary channel mapping, custom curves (including 12-point custom curves), adjustable dual rates, and channel locking. Preset and user- defined model templates, full model import/export, custom model images, configurable voice prompts, and support for Tools Lua scripts provide deep flexibility for advanced setups.
The built- in ExpressLRS LR 1121 module supports 2. 2.4GHz or Sub-G 900MHz operation with low latency and strong link performance, and supports Wi-Fi OTA firmware updates for the internal RF module. MAVLink passthrough enables compatible apps, such as QGroundControl and Betaflight Configurator, to be used directly on the radio for supported workflows.
HDMI input supports video from compatible digital video systems on the AX 12 display, while HDMI output mirrors the screen to an external monitor or projector for teaching, review, or team use. Using the DJI Fly app and a simple USB-C OTG connection, the AX12 can display the live video feed from DJI goggles directly on its built-in HD screen. This enables passengers, spotters, or instructors to view the flight in real time while the pilot continues flying with goggles. The mirrored display can also serve as a handy backup screen for safety or for recording or live-streaming the flight feed.
