Product overview
The RadioLink T12D provides 12 fully proportional channels for helicopters, fixed-wing aircraft, gliders, multirotors and racing drones. Bearing joysticks, three 3-position switches, one 2-position switch, two dials and two sliders provide physical control inputs. Its 2.8-inch, 320 × 240-pixel display uses a FreeRTOS and LVGL interface. Memory holds 50 model groups and 16 subsidiary-ID groups, while programmable mixing links channel functions. The case is designed to fit a JR-style module bay, and support for ELRS and TBS Crossfire modules enables external long-range integration.
The package supplies a T12D transmitter and R12F receiver, together with a Type-C upgrade cable, balance-port battery extension wire, hook and spring, instructions and packing box. Power options are two 18650 cells, eight AA batteries or a 2S–4S LiPo; an external high-frequency module limits LiPo power to 3S. Simulator use requires T12D V1.7.1 or above and R12F V1.6 or above, with an additional dongle for Phoenix Simulator. Fishing-point functionality requires an R16F receiver. Distance, current and endurance figures apply under favorable closed-environment conditions with unobstructed signals; results vary with environment, usage and firmware.
