1. Please check whether the novice mode is turned on, because the flying distance of the equipment in novice mode will be limited. Check whether the flight control settings have the function of opening the distance limit;
2. Please ensure that the aircraft firmware and App have been updated to the latest version;
3. Please try to close the App in the background, and then reopen it while keeping the plane connected to the App;
4. If only the visual positioning system is used indoors and there is no GPS signal, the lower flying height is 5 meters;
5. The 5.GPS signal is poor. When the down-looking vision system fails, the flying altitude is 50 meters.
