Description

The RadioMaster TX15 radio controller is engineered around a powerful STM32 H7 microcontroller, delivering the processing speed required for smooth EdgeTX operation and complex model configurations. Its integrated ExpressLRS system supports both 2.4GHz and 900MHz bands, offering pilots flexibility between high packet rates and extended penetration range, all with industry-leading low latency.

Structural and thermal design prioritizes durability and sustained performance. An aluminum heat sink and low-noise cooling fan manage thermals during extended use, while the robust gimbal assembly and customizable shoulder switches cater to various pilot preferences and flying styles. The controller supports multiple battery formats, including 18650, 21700, and 2S LiPo, providing flexibility for different runtime needs.

Key Features

  • High-Performance Processing: STM32 H7 MCU enables ultra-fast boot times, responsive UI, and seamless handling of complex mixes and scripts.
  • Dual-Band ExpressLRS Integration: Built-in ELRS module offers reliable communication on 2.4GHz or 900MHz, with adjustable output power and telemetry support.
  • Advanced User Interface: 3.5-inch IPS touchscreen with 480x320 resolution provides crisp graphics and intuitive touch controls, even in direct sunlight.
  • Precision Flight Controls: V5.0 Hall effect sensor gimbals with M4 sticks and adjustable spring tension deliver accurate, repeatable input with no potentiometer wear.
  • Comprehensive Expansion & Connectivity: Features a JR-compatible module bay for additional protocols, USB-C for data/power, built-in flash memory, and SD card support.
  • Intelligent Thermal Management: Integrated cooling fan and aluminum heat sink ensure stable operation and component longevity during high-power RF transmission.
  • Customizable Control Layout: Interchangeable shoulder switches and a built-in motion sensor (ICM-42607-C) allow for personalized trigger actions and control schemes.
  • Versatile Power System: Compatible with 18650, 21700 cells, or 2S LiPo packs (7.4V), featuring a smart balance charging circuit for optimal battery management.

Applications

  • Primary transmitter for long-range FPV drone builds utilizing ExpressLRS receivers for minimal latency control.
  • Versatile ground station for RC plane and helicopter pilots requiring the advanced mixing and scripting capabilities of EdgeTX.
  • Ideal controller for drone racing where fast processor response, customizable switches, and precise Hall effect gimbals are critical.
  • Suitable for cinematic FPV and mapping drones where reliable telemetry and extended communication range on the 900MHz band are beneficial.
  • Robust platform for DIY and experimental UAV projects leveraging its JR module bay for adding Crossfire, Ghost, or other long-range systems.

Frequently Asked Questions

What firmware does the RadioMaster TX15 run, and what are the minimum requirements?

The TX15 runs the open-source EdgeTX firmware on its transmitter board, requiring version 3.0.0 or later for full compatibility. The integrated RF module uses ExpressLRS firmware, which can be updated via WiFi or USB-C using the ExpressLRS Configurator. Always ensure both firmwares are updated to matching, stable releases for optimal performance.

What battery types are compatible with the TX15, and are they included?

The TX15 is designed for a nominal 2S voltage range (6.6-8.4V). It is compatible with a 7.4V 2S LiPo pack, two 3.7V 18650 cells, or a single 21700 cell (like a 5000mAh battery), using the appropriate tray. No battery is included in the package; you must supply your own compatible cells and charger.

Can I use other long-range systems like TBS Crossfire with the TX15?

Yes. The TX15 features a standard JR-compatible module bay at the rear. This allows you to install and use external RF modules such as the TBS Crossfire Micro TX, ImmersionRC Ghost, or other systems. The internal ExpressLRS module can be disabled when an external module is selected in the EdgeTX model setup.

How do I update the ExpressLRS firmware on the internal module?

The internal ELRS module can be updated via USB-C using the ExpressLRS Configurator tool in 'Passthrough' mode, or over WiFi if the module has that capability enabled in its current firmware. You must select the correct target (RadioMaster TX15 ELRS) and choose the desired packet rate and regulatory domain options during the flash process.
