Radiomaster TX16S MKII ELRS

Radiomaster TX16S MKII is a top-tier transmitter used by many of the best FPV pilots. The TX16S is a full-size format transmitter. With its large display and numerous switches, it is suitable not only for FPV drones but also for more complex models.

The Radiomaster TX16S uses the fourth generation of hall effect gimbals. Thanks to contactless position sensing, the control is more precise and avoids wear common with traditional potentiometers. The gimbals allow for easy external adjustment of spring tension and stick travel (38°–54°) without disassembling the transmitter. For the most demanding users, upgraded AG01 gimbals are also available (sold separately). The sticks are complemented by thirteen auxiliary switches. For configuration and telemetry display, a large 4.3" color touchscreen TFT display with 480×272px resolution is used. An integrated speaker provides audio feedback. For louder environments, a headphone jack is available. The transmitter can also be connected to a PC via the top USB port for simulator training.

For those who prefer physical controls, the Radiomaster TX16 retains the familiar scroll wheel and four-button layout known from other Radiomaster models. The TX16S MKII runs on the open-source firmware EdgeTX (successor to OpenTX), offering full customizability. It is powered by a pair of 18650 Li-ion batteries (not included) or a 2S battery. Charging is done via the bottom USB-C port.

One of the main advantages of this transmitter is the integrated ELRS module. ExpressLRS is an open-source project, with transmitter and receiver modules produced by multiple manufacturers. ELRS is currently one of the most advanced RC systems, offering reliable long-range control, high refresh rates, adjustable output power, WiFi updates, Bluetooth connectivity, and more. ELRS at 2.4GHz outperforms traditional RC systems while keeping antennas short. Bluetooth is especially appreciated by simulator enthusiasts, allowing wireless PC connection. On the back of the transmitter is a standard JR module bay for optional external RF modules.
