What is the difference between x7 and x7p? How many years is from the time x7p was built first?

Hi,
After three-time use the batteries are swollen. What should I do?

Question 1) How do you recommend us to charge the batteries? should we keep it charging for long time? or disconnect it as soon as it is fully charged?

Question 2) Should we use the battery till it full discharges?

Must I use the controller? Can't I simply and solely operate the aircraft with the iOS app?

What is the altitude mode? how does it differ from the hold position mode? In what scenarios I should use the altitude mode?

Hi,

It seems my gimbal doesn't work properly. When I turn the aircraft, it calibrates ( moves once up and down). However, during the flight and after calibration the gimbal doesn't move the camera at all. What should I do please?

Dear sir,
