How to Enable GPS Rescue Mode and failsafe
This is GPS Rescue Mode, not a GPS Return-to-Home (RTH) like DJI drones. It does not perform a fully automatic return. Before enabling this function, please conduct multiple tests. Open-source flight controllers do not guarantee absolute reliability, and there is a risk of flyaways or crashes. This guide is for reference only — we are not responsible for any damage or loss caused by using this feature. Please evaluate the risk for yourself. ❗❗❗❗
