Product overview
The RadioLink T12D is a radio-control transmitter for helicopters, fixed-wing aircraft, gliders, multirotors and racing drones. Its bearing joysticks are complemented by three three-position switches, one two-position switch, two dials and two sliders. A 2.8-inch, 320 × 240-pixel display provides the freeRTOS and LVGL interface. Storage holds 50 model groups and 16 model subsidiary ID groups. All 12 channels support programming and cascaded mixing, allowing one switch to operate multiple channels. The case accommodates a JR-style module bay, with ELRS and TBS Crossfire module support.
The package contains the T12D transmitter, R12F receiver, Type-C upgrade cable, balance-port battery extension wire, hook-and-spring set, manual and box. Its JST power input accepts 7.4–18 V from two 18650 cells, 2S–4S LiPo or eight AA batteries; an external high-frequency module limits LiPo supply to 3S. Simulator connectivity requires T12D V1.7.1+ and R12F V1.6+ firmware; Phoenix additionally requires a purchased dongle. R12F control distances are 600 m ground and 4000 m airborne in a closed environment with favorable conditions and an unobstructed wireless signal; results vary with environment, usage and firmware version.
