I didn't believe it

I want to share with you my experience during a flight. I don't know if I was very lucky or what else. Yesterday I was flying with tellofpv app, Younique WiFi extender, t1s controller and vr adapter. Suddenly I received two alerts video positioning not working and battery low.
The drone begun to land. But after landing it take off with sport speed in vertical flight and then landed again nearby. Today the drone is ok and it works perfectly. Please look the video.

Hi @Vitto

First Tello isn't build for flying above water. Because it using VPS or visual positioning, instead of GPS. So it needs a solid and even ground. Meanwhile water reflection will confusing Tello.

I tried fly over a pool and its doing okay, but when I hover above pool it losing its vps.

Make sure you have full battery when flying over water. Lost my first Tello due to autoland over a pond....expensive mistake.
