Just took my Tello for it's first flight in my living room and I'm very impressed. Bought it with the GameSir T1d controller and have to say that both of them are lightyears beyond any other small drone I have ever flown. The Tello stayed connected very well on WiFi even though my King Kong home WiFi router was only about four feet away. I was expecting to get a WiFi interference warning but never did. Of course I managed to run it into the curtains and chop a branch off the wifes fern with it (a bit out of practice with flying) but the Tello survived with no damage. Think I am going to wait for the rotor cage I have coming for it before I do any more flying though. Mabey I just go lucky but first impression of the T1d controller is that it's very precise and I wonder why it gets knocked so much but I guess time will tell if it continues to do well in the long run.
