The T12D is a 12-channel computer transmitter for recreational modellers, allowing the setting of basic functions such as deflection rates and direction. It also features a wide range of mixes for controlling a wide variety of models, including motorised aerobatic models, gliders, multicopters, cars, other ground vehicles and boats. It can work with an internal RF module with FHSS transmission system (same as T8FB/T8S or RadioLink R4GS/R6GS/R8X pistol transmitters), but also allows connection of external ELRS or TBS Crossfire long-range RF modules. It features a practical case that fits perfectly in the hand with a classic, time-tested ergonomic layout of controls.

Controls: The main functions are controlled by precise gimbals with adjustable self-centring spring tension and the option of moving the ratcheted throttle axis to the left or right. This allows you to freely select the mode 1–4 of the gimbals. The digital trims have audio signals for stepping and centre position. They are positioned slightly off-centre and are easy to reach. Additional channels can be controlled by two rotary knobs on the front panel and two rotary controllers with self-centring on the rear of the transmitter; four switches (three 3-position and five 2-position) can be used as channel switches or to turn program functions on/off. For easy programming, there are two buttons and a programming wheel/button and a 2.8-inch colour LCD with a resolution of 320×240 pixels. The transmitter uses the FreeRTOS operating system.

Transmitter power supply: The T12D can be powered by a variety of sources: 8 AA alkaline batteries or NiMH rechargeable batteries inserted into the holder supplied with the transmitter, NiMH rechargeable battery packs with 8 cells (AA size) or 2–4S LiPo or Li-ion battery packs. Power can also be supplied from a power bank via a USB-C port.

Transmission system: The T12D uses FHSS transmission with frequency hopping to ensure long range, reliability, and excellent anti-interference performance. For the internal RF module, you can choose between three FHSS transmission protocols with different transmission speeds (14 ms for analogue servos, 4 or 3 ms for digital servos), depending on the type of RadioLink receiver and servos used. When using a telemetry receiver, it allows telemetry transmission from the receiver and also telemetry from a connected RadioLink flight control unit, if used. For working with external modules, bidirectional ELRS and CRSF V2 protocols are available.

Software: The T12D offers programs for eight model types - classic aircraft, flying wings/deltas, multicopters, helicopters, cars, boats, tracked vehicles/tanks, and robots, with the option of cooperation with RadioLink control units for aircraft, drones, vehicles, or even fishing boats, including the relevant telemetry.

Compatible receivers: RadioLink R12F, R16F, R8FM, R8SM, R8XM, R8FGH, R8FG, R7FG, R6FG, R6F, R6FGM, R4F.
The R12F receiver supplied in the kit allows you to select several channel output modes (12 PWM outputs for classic servos, 11xPWM + S.BUS, 9xPWM+S. BUS+RX/TX CRSF, 10xPWM + RX/TX CRSF) with combinations of PWM outputs for classic servos, S.BUS serial output and input/output for CRSF. This allows you to easily connect classic servos, S.BUS servos and other devices, control units, etc.

Telemetry:

When using the internal FHSS RF module and RadioLink telemetry receivers, information about the receiver's supply voltage and RSSI signal strength is available; with the R16F receiver, it is also possible to measure and display the voltage of, for example, a drive battery up to 6S LiPo on the transmitter. You can also set threshold levels for low signal or low voltage alerts. When using a RadioLink control unit, telemetry data from this unit can be displayed.
When using an external RF module with CRSF protocol and an appropriate receiver, telemetry from this receiver can be displayed.
