Don't fly far from base in windy conditions!
The Return Home function is designed to bring the airplane back to you, and land it within 50 meters proximity.
It can be turned on manually by the user or automatically if the airplane flies out of the WiFi transmission range.
However, the changes in wind factor and additional inaccuracies, may divert the airplane from it's course.
Important tip: Every time the airplane passes close to "home" it calibrates it's location. Passing close to "home" occasionally will improve the return home route.
