RadioMaster TX16S MK3 Radio Controller (ELRS / M2)

The RadioMaster TX16S MK3 Radio Controller (ELRS / M2) is a premium full-size radio transmitter developed for pilots who need precise control, extensive customization, and flexible radio connectivity. Designed for FPV drones, multirotors, RC airplanes, and other compatible radio-controlled models, it combines modern processing hardware with a touchscreen interface and programmable physical controls.

Powered by an STM32H7 processor and running EdgeTX firmware, the TX16S MK3 provides a responsive interface for model programming, channel configuration, and control customization. Its integrated dual-band Gemini ExpressLRS system supports both 2.4GHz and Sub-G frequency bands, while the V6 Hall-effect gimbals deliver smooth and precise stick input.

The large 5-inch touchscreen, programmable RGB gimbal lighting, removable shoulder switch panels, and JR-compatible external module bay make this controller adaptable to different flying styles and RC setups. The M2 designation indicates Mode 2 configuration, with throttle on the left stick.

How to Use

1. Check the version: Confirm the ELRS configuration, Mode 2 layout, and regional radio version before use.

2. Install a compatible battery: Fit the supported battery configuration and verify polarity and voltage. Batteries are not included.

3. Power on the transmitter: Check the display, battery status, and startup behavior.

4. Configure the model in EdgeTX: Create a model profile and set up channels, sticks, switches, mixes, and other required controls.

5. Bind a compatible receiver: Use a receiver compatible with the transmitter's ExpressLRS system and follow the appropriate binding procedure.

6. Verify control directions: With propellers removed where applicable, confirm channel mapping, control direction, switch assignments, and failsafe behavior.

7. Check radio performance: Perform the manufacturer's recommended range check before operating your model.

8. Maintain firmware compatibility: Update transmitter and receiver firmware only with compatible versions and follow official instructions.

Important Notes

• ELRS compatibility: The integrated radio system is ExpressLRS. Receivers using other protocols may require a compatible external RF module.

• Dual-band operation: Supported frequency bands and available output configurations depend on the regional version, firmware, and applicable regulations.

• Battery not included: Purchase compatible batteries separately. Confirm battery size, voltage, and connector compatibility before installation.

• Mode 2 configuration: Mode 2 places the throttle on the left stick. Check the selected configuration if you prefer another stick mode.

• Receiver-dependent channels: The actual number of usable channels depends on the receiver, protocol, and model configuration.

• Firmware requirement: The manufacturer specifies EdgeTX 3.0.0 or later for the TX16S MK3.

• External modules: Confirm module compatibility with the JR-style module bay before purchasing.

• Flight safety: Verify failsafe settings and perform a range check before every new model setup. Follow local drone and radio-frequency regulations.

• Package contents: Memory cards and batteries are not included. Confirm the seller's package listing for any additional accessories.
