the iconic "cross" design. Engineered exclusively for digital FPV, it eliminates analog OSD, integrating a flight controller, ESC, and ELRS 2.4G RX into one lightweight, streamlined unit for effortless setup and maintenance. Equipped with newly developed BEC and ESC, it’s finely tuned to meet the demands of 1S HD whoops, delivering superior digital image transmission and setting a new standard in 1S HD flight controllers.

Note: Stay tuned for our upcoming 4IN1 version with the analog OSD integrated.
