Support for ELRS, TBS Crossfire and long-range modules
The T12D supports ELRS, TBS Crossfire and other common long-range modules, and several parameters such as protocol, baud rate and WiFi mode can be adjusted directly via the transmitter depending on the module and configuration.
Advanced communication technology
The T12D uses upgraded and optimised communication technology focused on faster response time and better fault tolerance, where FHSS spread spectrum with 67-channel pseudorandom frequency hopping contributes to stable signal transmission and strong interference protection in demanding environments.
Strong interference protection for many simultaneous users
The T12D is developed for a stable signal on all 12 channels even in environments where many users operate at the same time, for example competitions, training, racing drones and larger RC events.
12 fully proportional channels
The T12D has 12 fully proportional channels that can all be programmed, giving great flexibility for models where several servos, functions, mixes or special solutions need to be controlled individually.
Wide model compatibility
The T12D supports many different model types, including helicopters, aeroplanes, gliders, multirotors, racing drones, soccer drones, engineering vehicles, racing boats, robots, lawn mowers and bait boats, and suits both classic hobby builds and more specialised projects.
freeRTOS and LVGL GUI
The T12D uses freeRTOS together with the LVGL GUI for a colourful and responsive interface that makes advanced settings more accessible directly in the transmitter.
High configurability and a clear colour display
The T12D has a 216 MHz main frequency, a 2.8-inch colour display with 320 x 240 pixels, three 3-position switches, one 2-position switch, two knobs, two sliders and an ergonomic design for good control over several functions.
Built-in simulator function
The T12D transmitter and the R12F/R16F receivers have integrated simulator support after a firmware upgrade to V1.7.1 or later, with no external dongle required: just connect via a Type-C cable for use with compatible simulators such as TRYP FPV, AeroFly, Uncrashed, Liftoff, FPV LOGIC and Velocidrone on both macOS and Windows.
Trainer function with wireless and wired mode
The T12D supports both wireless and wired trainer function, where the wireless mode lets the instructor move freely within up to 600 metres, making the radio practical for flight schools, clubs and training.
Real-time data from the flight controller
In bait boat mode, the T12D can store up to 100 named GPS coordinates for fishing spots and show real-time data such as distance, satellite count, vessel voltage, longitude, latitude and route maps; for the fishing spot function the R16F receiver should be used according to the documentation.
Reset of user-defined settings
The T12D supports resetting user-defined settings at the push of a button, where OEM manufacturers, educational institutions and individual users can reset their own, OEM-configured or the manufacturer’s default parameters.
Switch flight mode with one click
After an upgrade to firmware V1.8.2 or later, the MODEL function includes pre-installed configurations for, among others, the soccer drones A560, D460, SU27, 200 mm and 400 mm as well as the optical flow drone F108, and the current flight mode is shown in the main interface to reduce the risk of using the wrong one.
Several languages and customisable voice prompts
The T12D supports several menu languages, including Chinese, English, German, French, Russian, Japanese, Spanish, Korean, Thai and Polish, and voice prompts can be customised in several languages.
Programmable cascade function for mixing controls
All 12 channels can be programmed to advanced settings and several mixing controls can be combined so a single switch can control several channels, useful for both daily training and competitions.
Wide receiver compatibility
The T12D comes with two 12-channel R12F receivers and is compatible with several other RadioLink receivers for different model types.
- R12F: Standard receiver included in the package
- R16SM: For racing drones and multicopters
- R16F: For helicopter, aeroplane, multicopter, car, boat and robot
- R8FG and R8FGH: For lawn mowers and bait boats
- R8EF: For aeroplane and helicopter
- R8SM, R8FM and R8XM: For racing drones and multicopters
- R6FG, R6F and R7FG: For cars and boats
- R4FGM: For mini RC cars
User-friendly menu
The T12D has a menu structure for navigation and parameter setting that is powerful yet easy to use, so the transmitter can be put to use quickly.
R12F receiver with online upgrade
The included R12F receivers support online upgrade via a Type-C data cable connected to a computer, support SBUS, CRSF and PWM, and support the simulator function after a firmware upgrade.
Reverse-polarity protection and several power supply modes
The T12D uses a standard JST battery connector with a wide input voltage range and can be powered by two 18650 lithium cells, a 2S–4S LiPo battery or eight AA batteries (max 3S LiPo with an external high-frequency module); it ships with an 18650 holder, an AA holder is needed for AA batteries, and the circuit design protects against reverse polarity.
Efficient power supply for longer battery life
The T12D uses a switched-mode power supply (SMPS) with an operating current of 100 mA ±10 mA at 8.4 V DC, which according to the documentation gives up to 50 % lower power consumption and, with an 1800 mAh LiPo battery, up to about 12 hours of use.

Good to know
The maximum range is tested in open areas without interference and may in practice vary depending on the model, installation, antenna placement, surroundings and signal conditions. The simulator function and online upgrade require a firmware upgrade and a Type-C data cable respectively, and you should always check that the receiver, signal type, model type, firmware and any long-range module are compatible. The T12D is an advanced radio transmitter intended for people with an understanding of RC systems, channel settings, model configuration, power supply and safe handling of models.
