HelloRadioSky V12 CNC MAX ELRS FPV Radio Transmitter

The HelloRadio V12 CNC MAX  ELRS Radio Transmitter is a compact, premium-feel FPV radio transmitter designed for pilots who want modern ExpressLRS performance in a smaller gamepad-style form factor. Finished here in Grey/Red, the V12 CNC MAX combines a sharp 2.4-inch IPS colour screen, CNC metal controls, Hall sensor gimbals and EdgeTX firmware into a radio that feels far more serious than its size suggests.

Built around an STM32H750 processor and LR1121 ExpressLRS RF chip, the V12 CNC MAX is made for fast response, reliable control and clean everyday usability. With up to 1W RF output, internal and external antenna support, and 2.4GHz ExpressLRS, it is well suited for FPV drones, wings and other ELRS-compatible RC models.

Product Highlights

• 2.4GHz ExpressLRS built in – modern low-latency control with excellent range potential.
• Up to 1W RF power – compact radio size without giving up serious link performance.
• STM32H750 processor – strong processing power for a fast, responsive EdgeTX experience.
• Hall sensor gimbals – smooth stick feel with contactless sensing for long-term accuracy.
• CNC metal gimbals and buttons – a more premium, durable feel compared with standard plastic controls.
• 2.4-inch IPS colour display – clear menus and model setup in a compact radio body.
• USB-C multi-function port – supports charging, simulator connection, firmware upgrades and data transfer.
• Dual-fan cooling – helps keep the radio stable during higher-power use.
• 2 × 21700 battery compartment – larger cell support for longer flying sessions.

Compact Radio, Serious Hardware

The V12 CNC MAX is small enough to carry easily, but it is not a toy-grade radio. The CNC metal hardware, Hall gimbals and colour screen give it a premium feel, while EdgeTX gives pilots the flexibility to build model profiles, mixes, switches and logic functions around their own flying style.

ExpressLRS Built In

With an internal 2.4GHz ExpressLRS RF module and LR1121 RF chip, the V12 CNC MAX is ready for today’s ELRS-based FPV drones. ExpressLRS is widely used across modern FPV builds thanks to its strong link performance, low latency and active development.

USB-C Convenience

The USB-C port keeps everyday use simple. Use one cable for charging, simulator connection, firmware upgrades and data transfer. The radio also supports online firmware upgrade via USB-C and offline upgrade using an SD card.
