I have the Td1 Hooked up to an Iphone 7. It took a few attempts (My faults) but I now have it up and running. I will admit the Gamesir Td1 works really well. Now I need my Wifi repeater to come in.
It took quite a while for mine to come in.. I do feel it is worth the wait. I was flying this last weekend and my son in law picked up the controller and had a blast with my Tello. He now wants one for his Tello.
