Welcome to the Forum from Chicago the Windy City. Hope you have some kind of Check list for preventive actions to make sure for instance. To make sure that remote control is 100 % charged, your pad is 100% charged, battery 100% charged. Every time I fly, always make sure these big three are ready to go before every flight. Been flying over 3 years now, and always make sure these 3 I mentioned are fully charged. I remember being a newbie, and very excited about getting it up in the air, without reading very important info. Very few guys read the manual from cover to cover at the start, but it will save you lots of headaches in the future to know info about RTH. To understand how the RTH feature works, it has 3 features, which one is the best for you? Anyway, fly safe, these drones are fun, and very sophisticated
the more you pay, the more understanding is needed on how it works. Fly safe and Have fun.
