-
During normal flight, the plane suddenly flew uncontrollably in one direction？
Calibrate the aircraft first. If a similar situation still occurs during calibration, there is a problem with the flight control board, which needs after-sales service.
-
The aircraft deviated after collision or explosion？

In n-gear mode, the plane will fly for a period of time, but it will land automa
