RadioMaster TX15 Radio Controller ELRS Iron Grey
This versatile module combines durability, ease of use, and innovative features, making it an outstanding choice for demanding setups.
Take Control of Demanding FPV Flights – RadioMaster TX15 Radio Controller ELRS Iron Grey
RadioMaster TX15 Radio Controller ELRS Iron Grey is built for pilots who want high-performance ExpressLRS, comfortable operation, and portable hardware in one radio. The built-in Semtech LR1121 transceiver supports 2.4GHz and 900MHz ELRS, while the STM32 H7 processor powers fast EdgeTX operation, quick model switching, and responsive script execution. It is a strong choice for everyday FPV, long-range flying, and more challenging RF environments.

Precision You Can Feel on the Sticks
The V5.0 Hall gimbals are designed for smooth, repeatable, and accurate control. Hall sensors and precision bearings help create a more natural stick feel during FPV flight, aerobatics, landing approaches, and simulator training. This matters for pilots who expect control without unwanted play, rough movement, or unpredictable stick response. RadioMaster lists V5.0 Hall sensor gimbals as standard on the TX15.
Reliable Link in Demanding RF Conditions
The built-in Semtech LR1121 transceiver supports ExpressLRS on 2.4GHz or Sub-G 900MHz, giving pilots more flexibility across different flying styles. This setup works well for everyday FPV use and for locations where the radio environment is more challenging. The radio is built for low-latency response, a reliable link, and confident control in more demanding setups.


Clear Setup Visibility Even Outdoors
The 3.5-inch IPS color touchscreen makes model setup, EdgeTX navigation, and profile changes easier to manage. With 600 nits brightness and 480 x 320 resolution, it remains practical to read outdoors, including bright flying spots. This is useful for pilots who frequently adjust models, switch profiles, or tune settings directly at the field.
Easier Transport Without Giving Up Signal Quality
The foldable antenna makes the radio easier to pack into a bag, backpack, or FPV case. When deployed, it still supports the signal quality needed for reliable control, while the folded position helps reduce the risk of accidental damage during transport. It is a practical detail for pilots who travel often, fly in the field, or carry their radio for quick FPV sessions.
