Except Xiao, Yu Mini, Yu Air, Yu Air 2, Yu 2 and Wu 2 models, all other models support hotspot following function (mobile devices need to have GPS module).
When the GPS signal of the aircraft is normal and the number of stars reaches 14+ (the number of stars of Elf 3 Std reaches 10+), start the hotspot following function, and the distance and altitude between the aircraft and people will keep the set value to follow the flight.
