RadioMaster TX16S Mark II Radio Transmitter (Hall Gimbals / Multiple Protocol Versions)

The best just got better! Introducing the TX16S Mark II, the ultimate open-source radio. It works with multiple radio frequency (RF) protocols, plus it has expandability and upgradeability for the future, including the Touch panel which will support future touch-compatible versions of OpenTX/EdgeTX firmware and UART expansion slots. The Radiomaster TX16S comes with super smooth precision hall-sensor gimbals with CNC facias, offering a refined look and great performance. It also has a built-in USB-C charger, class-leading ergonomics, internal multi-protocol modules as the standard, along with improved key layout, menu navigation, and sliders. Suitable for RC drones, airplanes, fixed-wing, and more!  Plus, the RadioMaster internal RF module will support firmware updates directly from the Radio's operating system, without having to worry about any complicated update procedures.   FEATURES: Improved internal circuitry and optimized power supply. New charge circuitry with integrated reverse-polarity protection. Optimized charge IC now allows up to 2.2A internal USB-C charge current. Rear-mounted audio jack provided headphone output. V4.0 Gimbal improved centering and temperature stability (Same circuitry as AG01). Optional high/low rear grips are included for improved ergonomics. Improved S1/S2 knobs with clear center-detents. Improved LS/RS Sliders with smoother feel and better center-detents. Redesigned battery cover for improved battery access. Retooled body shell with improved fit and finish. Trainer socket changed to standard TRS 3.5mm socket. Rear DIY Socket added for personalized mods. Improved internal plastics for better longevity. Works with TBS Crossfire, TBS Tracer, ExpressLRS, ImmersionRC Ghost & more via external JR module bay. External modules sold separately.   COMPATIBILITY: DSM/DSMX FlySky FlySky AFHDS2A FrSky Futabas SFHSS HiSky, Syma, ASSAN and most other Chinese models (see full list here) Hubsan Walkera Devo     REQUIRED: (2) 18650 Li-Ion Batteries (tray included for this size battery)    Alternate Battery Options: (2) 21700 1S Li-Ion Batteries (tray sold separately) (1) 21700 7.4v 2S Li-Ion Pack with 3-Pin JST-XH Connector (1) 7.4v 2s Li-Po Battery Pack with 3-Pin JST-XH Connector   SPECIFICATIONS: Model#: HP0157.0019 4IN1 or HP0157.0020 ELRS Size: 287x129x184mm Weight: 750g (without battery) Transmission frequency: 2.400GHz-2.480GHz Transmitter module options: 1) Internal 4-in-1 multi-protocol module*Chips Included: CC2500 CYRF6936 A7105 NRF24012) ELRS Transmitting power: Internal 4-in-1 multi-protocol module : Max 100mw (protocol dependent) SD card: 256MB by default, 8GB maximum Antenna gain: 2db (transmit power adjustable) Working current: 400mA Working voltage: 6.6-8.4v DC Remote control distance:> 2km @ 22dbm Radio firmware: EdgeTX Module Firmware: Multiprotocol- Module (4IN1) or ELRS Channels: Up to 16 channels (depending on the receiver) Display: 4.3-inch TFT full-colour touch display with a resolution of 480 * 272 Gimbal: Option 1: V4.0 Hall sensor with Aluminium fasciaOption 2: AG01 CNC Hall sensor Module Bay: JR compatible module bay Upgrade method: Supports USB-C online / SD card offline upgrade Protocols by Chip:1) DSM/DSMX, Walkera Devo (Cypress Semiconductor CYRF6936 Chip)2) FrSky, Futabas SFHSS (Texas Instruments CC2500 Chip)3) FlySky, FlySky AFHDS2A, Hubsan (Amiccom A7105 Chip)4) HiSky, Syma, ASSAN, and most other Chinese models (Nordic Semiconductor NRF24L01 Chip)   HELPFUL LINKS: RadioMaster TX16S User Manual Multi-Module Info Receiver Protocol Compatibility List OpenTX Firmware INCLUDES: (1) TX16S Mark II Radio Controller(1) 18650 Tray(1) USB-C Cable(1) Screen Protector(1) Pair of Flat Grips (1) Pair of Raised Grips (installed on radio by default)(1) TX16S Key Chain NOTES: Computer port for simulator use and/or firmware updates is on the top of the Transmitter while the charging port is on the bottom of the Transmitter.
