GX12 Crush ELRS Radio Controller 2.4GHz Transmitter With M2 Gimbals (Iceberg Blue)

The GX12 with a bolder look

The GX12 Crush takes the dual-band performance of the RadioMaster GX12 and puts it in a new set of colours. This is the Iceberg Blue version, and the same radio is offered in Iron Grey, Frost White, Mint Mist, Hot Pink and Lemon Twist Yellow. The core idea is simple: it runs the Gemini Xrossband ExpressLRS platform, transmitting on 2.4 GHz and 900 MHz at the same time for a more reliable link.

Running two bands together is a real advantage on long-range and difficult-terrain flights. The 900 MHz band travels farther and penetrates obstacles better, while 2.4 GHz gives the fastest update rate. When one is hit by interference or a blocked path, the other keeps the link alive.

Hardware notes worth knowing

The gimbals are the GX01 type with 1000 Hz digital output and 3D Hall sensors, and the display is a 128x64 monochrome OLED. The radio runs EdgeTX for the transmitter and ELRS for the RF module, offers up to 16 channels and connects by USB-C. Power comes from a 7.4 V two-cell LiPo or a 21700 5000 mAh cell, with 2S smart balance charging, and current draw is 390 to 1000 mA. It measures 183 x 148 x 78 mm and weighs 573 g, and a cooling fan is fitted.

This is an ExpressLRS radio, so choose receivers that support ExpressLRS on the bands you plan to use. Dual-band flying needs a receiver that supports Gemini, so check that before you build.

Who it is for

Long-range pilots and anyone who wants a personal touch on a serious radio. It is a good step for pilots who already fly ELRS and want the extra resilience of dual-band. It comes as a single radio in Iceberg Blue, so plan your own batteries.
