Thought I would share this, shows what can happen when signal from controller to Mavic Mini is lost by the shoulder of a mountain. In this case, my RTH was set to 400', much lower than the mountain top. I did not expect signal loss because I was flying above the mountain. However, I got too low to the ground and the shoulder of the mountain blocked the signal and triggered an automatic Return To Home. Be sure to watch the Flag fly over afterward, very strange guy playing Peekaboo??
