DarwinFPV F411 45A ELRS AIO (CineApe35 Compatible)This is a unique AIO that meets the needs of today's industry. It has a 25. 5x25. 5 mounting hole pitch, but it does not rotate 45! The advantage of this is a more compact and safer installation layout. Unlike traditional AIO, the electronic components on both sides are exposed outside the frame. It is more like a stack, but only one layer. You can install DJI O3, VISTA, HDZERO, Avatar, and other digital VTX on it, which is very convenient. Package
