RadioMaster TX15 MAX – Power Without Limits
RadioMaster continues to redefine the open-source radio control landscape — and the TX15 MAX sets a new benchmark.
After years of close collaboration with the open-source community and passionate pilots worldwide, RadioMaster proudly introduces its most powerful radio yet. Driven by the high-performance STM32H7 processor, the TX15 MAX delivers ultra-smooth EdgeTX control, instant model switching, and lightning-fast script execution. With 4GB of onboard flash storage plus MicroSD expansion, you’ll have virtually unlimited space for models, sounds, scripts, and custom themes.
At Aerobertics, we believe performance should never compromise reliability — and the TX15 MAX delivers both.
Dual-Band ExpressLRS Performance
Equipped with the advanced Semtech LR1121 transceiver, the TX15 MAX supports both 2.4GHz and 900MHz ExpressLRS (ELRS), providing exceptional range, ultra-low latency, and rock-solid RF performance — even in challenging environments.
Whether you’re flying daily or pushing limits in demanding RF conditions, this radio is engineered for absolute confidence.
Now also compatible with mLRS, offering a transparent serial link solution with excellent signal integrity and high data rate — perfect for advanced and specialized applications.
Designed for Performance. Built for Pilots.
The TX15 MAX combines premium materials, advanced cooling, and ergonomic innovation:
- 3.5-inch IPS Touchscreen (480×320, 262k colors, 600 nits brightness) — crystal clear even in direct sunlight
- AG02 CNC Aluminum Hall Gimbals (anodized red, black, or gold) — ultra-smooth and 20% lighter
- Adjustable vertical & horizontal stick travel
- Carbon-fiber-look case with upgraded aluminum buttons
- Scroll wheel navigation
- Customizable RGB LED gimbal light rings (LUA-controlled)
- Advanced cooling system with aluminum heat sink & low-noise fan
- Foldable antenna for portability without signal compromise
- Smart balance battery circuit for optimized runtime
- Built-in gyro (TiltX / TiltY) for motion-triggered functions
- Built-in microphone (future expansion ready)

IMPORTANTE NOTE FROM RADIOMASTER - APRIL 2026
Due to ongoing global supply chain constraints, flash memory chips have experienced significant instability in supply along with large cost increases. Despite the best efforts of our procurement team the supply remains the highest concern and poses a genuine risk of production interruption that could halt manufacturing of these transmitters.
To ensure continuous and stable production, and to avoid any disruption toyour supply, we have made the difficult but important decision to change from 4GB to 512MB in the TX15 series and TX16S MK3 series transmitters ordered on or after April 3, 2026, with corresponding product SKUs updated accordingly. While today’s price of 512MB flash units is now above the initial price of the 4GB flash units the 512MB flash units remain stable in supply. We will absorb the increase and this change will allow us to retain the current retail price and dealer margin while helping to reduce risk of production disruptions.
Mass production orders with this configuration change are expected to be delivered around late May 2026. During the transition period between the old and new versions, there may be mixed shipments of products with different memory configurations from our warehouse. We kindly ask all partners to take note of this and to communicate the change to end customers in advance. Orders already placed will retain their originally memory configuration. We sincerely apologize for any inconvenience caused by this adjustment. Thank you for your continued trust and understanding. If you have any questions, please contact your business representative.
