A 692ft flight with video from the Tello and a screenshot of the flight-log from the tellofpv app. The VPS kept dropping I think due to the position of the sun and shadows? It dropped out pretty bad at the end but I brought it back nonetheless equipment was as follows: (Air Side) Tello with Xiaomi mi repeater with patch antenna traces removed and two 1/4 wavelength piece of wire direct soldered to the mi repeater board. (Ground Side) Android device and TP-Link N300 from amazon modified with standard 2.4 rubber ducky antennas. Flight was in a fairly open area but was about 15-20ft horizontal to a power line.
