Hi everyone! I got my Tello just a week ago and after some initial flights and reading some threads here, I decided to get a Xiaomi repeater so I could get better video and range. My question here is how to take most profit out of the connection with the drone? I read the repeater should be a few meters away from the phone and any metals but regarding the power bank, should it be connected via cable or straight on to the USB port? What's the best set up for least interference? Thanks!
