Greeting from NSW My Tello is set up with the Tals app and can fly up to 30m high and I use a wifi repeater 2 and a Gamesir T1s controller. You think it' good now? with this set up it is truly amazing.What an amazing mini drone this little Tello is. 80 odd grams and flying at 10m high in the wind. I have found if it has plenty of stuff to see underneath it, it holds hover amazing at 10m I’m a breeze
