Excuse my ignorance, since I don't know much about RC stuff. Other than when you did the take off, I didn't see you make any stick input during the flight. Can you pre program the flight path with that controller?
Edit: never mind, rewatched it and you did. My mistake.
I can get uninverted signal from my micro receivers. So it should be pretty straight forward. 8266 is already in transit to my adress, have plenty of MicroUSB connectors in my electronics drawer... I think I need to try it, once I receive all the components Sadly Tello has no memory, would be fun to shoot photos and video using my Taranis.
Which variant 8266 do you use? There are a couple of variants available?
And a stationary variant could be used, too. Instead of hooking up the 8266 and the receiver on top of Tello , place it somewhere.
