I am always so impressed by these videos. I have tried to fly my Tello outdoors, rather unsuccessfully. The slightest wind seems to take the bird away (even in Fast mode). I have two other larger drones that I fly outdoors (Breeze 4k and Anafi) but I salute you all that get such great outdoor results and fly such great distances and heights with your beloved Tellos. Maybe I just need to gain some confidence and let her get up there a little higher and a little further away (I have a Xiomi Mi extender).
It is also impressive that you are flying without a controller. Nice.
Kudos to you.
