phantom 3 Standard Fly with a height of 70-80M Why remote signal weak - missing ?
App DJI Go Show Text " remote controller signal " Ask for a solution.
Because you were flying straight up which is always the worst angle for keeping a good signal strength.
It's all about antenna geometry.
You get optimum signal when the antennas are parallel and facing each other.
Try flying out a bit rather than straight upwards.
