Can you tell me more about your repeater there? I'm pretty new to the Tello, and definitely find the range and quality from the phone alone to be lacking.
Which repeater is that, and what kind of tripod do you have it on?
It's a xiaomi 2 repeater on a gopro tripod. The battery pack is one that I got at Five below and is attached with adhesive to a screw plate and attached to the tripod. It works pretty well.
