RTH feature on high-end devices goes even a step further. You see, if there’s a shortage of battery, it will automatically start returning your drone to the takeoff location.
Likewise, if there’s interference between the drone and its controller, the RTH feature will turn on automatically, getting your drone back safely.
The latter mostly happens when the drone gets out of its designated range. In that scenario, the only safe way of getting your drone back is the automatic return to home feature. So, for all of you who thought this was a gimmick, I’m sorry to inform you were wrong.
