Radiomaster TX15 ELRS 868MHz/2.4GHz

Radiomaster TX15 is a great radio suitable for beginner and advanced pilots. TX15 is a practical combination of size, comfort, and features. The Radiomaster TX15 uses large hall gimbals similar to the TX16 or Boxer model. For further control of the model, 4 switches, 2 rotary knobs, 2 buttons (which can be replaced with switches), and one six-position channel controlled by buttons with adjustable LED backlighting are available. The radio setup is the same as in other Radiomaster models using 6 buttons and a rotary knob. At first glance, the large 3.5" touchscreen with brightness of 600 nits stands out. Thanks to the powerful STM32H7 processor, the transmitter has a fast response. TX15 features internal memory, which can be expanded with a MicroSD card. The radio uses fully configurable firmware EdgeTX (successor to OpenTX). You will also appreciate the case for the transmitter included in the package. For future expansions, the transmitter is equipped with an integrated microphone. The transmitter also includes an embedded gyro. The built-in gyroscope with TiltX/TiltY functionalities unlocks advanced control options – allowing for switching, rotating cameras (pan/tilt), or activating telemetry messages simply by tilting the transmitter.

A significant advantage of the radio is the integrated ELRS module based on the Semtech LR1121 chip, which supports the 2.4GHz and 868MHz bands. The bands can be easily switched, allowing you to choose as needed. The 2.4GHz band is suitable for freestyle and racing flying with low latency, while the 868MHz band offers a very long range. 

ExpressLRS (shortened ELRS) is an open-source project, and the transmitting and receiving modules are manufactured by multiple producers. ELRS is currently one of the most advanced RC transmissions. It offers a reliable long-range link, high refresh rates, adjustable power, Wi-Fi updates, Bluetooth connectivity, and more. Bluetooth will be particularly appreciated by simulator enthusiasts, as it allows wireless connection to the PC. The internal module is actively cooled by an internal fan. The foldable dual-band antenna makes transportation easier.

On the back of the transmitter, there is a standard large JR bay for potential expansion with an external transmitting module. TX15 is powered by a 2S battery. The package includes a bay for a pair of 18650 Li-Ion batteries. Larger 2S batteries can also be used for longer runtime. The battery is charged via a USB-C connector, which is also used for firmware updates or connecting to a simulator.
