The wind trap, in under a minute
A drone's advertised range assumes still air. Fly out with a tailwind and it feels like the battery will last forever, until you turn for home and fight the same wind the whole way back. That is the wind trap: the outbound leg lies to you, and the return leg is where flights get stranded. This short shows why RangeSight plans around the leg you actually have to make, not the one that feels easy.
