The problem that the aircraft deviates too far from the route during automatic flight:
Check whether the aircraft is leveled, adjust the aircraft to fly straight and maintain altitude without human intervention. Second, check the wind direction and wind power, because high winds can also cause such failures, you should choose to take off the drone when the wind is low.
Furthermore, check the balance instrument is whether it is placed in a suitable position, switch the aircraft to manual flight, and put the balance instrument in the appropriate position
