RadioMaster TX12 MKII ELRS/CC2500 Radio Controller

The RadioMaster TX12 MKII is a compact handheld transmitter for FPV pilots who want a smaller radio for everyday flying, offered with either an internal ExpressLRS (ELRS) 2.4 GHz module or a CC2500 multi-protocol module. It pairs dual gimbals, front buttons, top switches and a built-in display, so the layout stays usable without adding unnecessary bulk.

Key features

• ELRS version: ExpressLRS control on 2.4 GHz for the common ELRS receiver ecosystem used on modern FPV quads; the CC2500 version covers receivers that use CC2500-based protocols instead.

• Compact body with an ergonomic grip and side controls for pilots who prefer a smaller transmitter.

• Dual gimbals provide separate left and right stick control for throttle, yaw, pitch and roll.

• Top switches and front buttons add channels for arm, mode, beeper and other auxiliary functions.

• Built-in display keeps model selection and radio settings visible on the transmitter.
