Where I live near Denver it’s more often windy than not. In fact, it keeps me grounded more than any other weather issue here. The P3//P4 (I have both) each handle a 15.6 mph wind, like Meta4 said. I’ve got no problems up to about 18 to 19 mph is when I notice a difference in flight performance only. I’ve flown in windier conditions (unexpected) and the gimbal is so good that there were no signs of shakiness in the video. The wind can really throw the bird around quite a bit and you may not see that translate to your videos. You may want to look into an app called UAV forecast. It will tell you the current wind speed at any height you want to know, which is so helpful. Just because you’re feeling a 5mph breeze @ AGL doesn’t mean that’s what’s happening 200, 300 or 400 feet up. I can see 20 to 30 mph differences between those heights and as Meta4 was saying - you bet that effects RTH options, etc. Also, if you’re not filming in your way back home with a good tailwind it’s still exhilarating to look down at my controller and see it’s headed my way at 67 or 68 MPH. Just sayin...
And I got the biggest kick out of your video. The music and the way you filmed the Phantom - playful. Unique. And I don’t think I saw any trees blowing from wind there and that windmill was still. Where is that place? Southwest TX? Arizona? Awesome cactus’ - beautiful area. Perfect place to fly.
