I try to install FPV 2.4 G with my FC40. I have contacted Ready Made RC Support and he suggested to disable FC40 2.4 G video link out of the box. Below is what the support suggested. Q: I am a newbie with quad environment . My DJI FC40 operate in 5.8 g frequency with DYS gimbal. I use Gopro 3+ to record flight and plan sent video back to receiver at 2.4 G. would it be achievable? A: The FC40 uses a 5.8G radio link, and a 2.4G video link out of the box. If you plan to use a stand alone 2.4G video link as we've been over then you'd need to ensure your 2.4G video link was disabled on the FC40. I'm not familiar with that process, but that's what you need to do and verify is off or you might see interference with the added video link. I dont plan to fly my quad farther than 500 meter. would FPV1024 Plug and Play 2.4Ghz 1000mW Wireless System - Lawmate satisfied my need? Can anyone shed my some light? :?
