It is a pleasure to welcome you to the Tello Pilots forum.
I hope that you will be able to use the forum for the exchange of innovative ideas and as a resource for current developments in Tello quadcopters.
also hello from CZE. got my tello yesterday together with WLAN repeater but haven't time to fly it for more than few minutes yet. still , as much as I tried, it's incredibly stable when hovering and really easy to control.
I've been flying only various R/C helicopters so far (still have some of them) but no drones and this little Tello could be a nice introduction to this category of aircrafts.
