Radiomaster TX16S MK3 ELRS Xross 868MHz/2.4GHz

Radiomaster TX16S MK3 is a high-end RC transmitter, suitable even for the most demanding pilots. The main advantage of the TX16S MK3 is its large 5" touchscreen display and dual-band Gemini ELRS module, which ensures maximum reliability of the RC transmission.

The transmitter features large V6 hall gimbals with four bearings, providing smooth operation, high precision, and long lifespan. The gimbals are mechanically adjustable and can set the range of motion and spring stiffness. Around the gimbals, there are RGB LED rings that can be controlled via LUA scripts. For additional model control, there are 8 switches, 2 rotary knobs, 2 sliders, and one six-position channel controlled by buttons with adjustable LED backlighting. The radio setup is the same as other Radiomaster models using 6 buttons and a rotary knob.

At first glance, the aforementioned 5" touchscreen IPS display with a resolution of 480×800 pixels stands out. Thanks to the high brightness and wide viewing angle, the display remains legible even outdoors in sunlight. With a powerful STM32H7 processor, the transmitter has a fast response. The TX16S MK3 has 4GB of internal memory, which can be expanded with a microSD card. The radio uses fully adjustable firmware EdgeTX (the successor to OpenTX).

For future expansions, the transmitter is equipped with a built-in microphone. It also includes an integrated gyro. The built-in gyroscope with TiltX/TiltY functions unlocks advanced control options – allowing to trigger switches, tilt cameras (pan/tilt), or activate telemetry messages simply by tilting the transmitter.

The internal ELRS transmission module uses two LR11211 chips, each capable of transmitting on a frequency of 2.4GHz or 868/915MHz with power up to 1W. The module can operate in Gemini modes at 2.4GHz or 915MHz, or in XROSSBAND mode, where one transmission chip transmits at 2.4GHz and the other at 868/915MHz (this function must also be supported by the receiver). Thus, the Radiomaster TX16S MK3 offers high resistance to interference. It can also be used with standard ELRS receivers, which operate with one antenna on one frequency. The radio is equipped with two antennas – one located on the top side of the radio in an antenna holder and the other in a plastic handle. The module is actively cooled by a fan.

On the back of the transmitter, there is a standard JR bay for potential expansion with an external transmission module. The TX16S MK3 is powered by a pair of 18650 Li-Ion cells or 2S LiPo batteries. Charging is done via a USB-C connector, which also serves for connecting to the simulator and transferring data to the radio's memory. Thanks to the ELRS module, connecting to the simulator is also possible wirelessly via Bluetooth.
