I'm exporting a video right now of some high wind flying from a high structure. Once it's done exporting and uploading it'll be on my channel on you tube slash norgazmic
I haven't heard one person mention the UAV Forecast app.
It's your bird, if you want to fly in 40 mph winds at ground level, the wind and gusts are going to be too high even for sport mode to overcome.
