  If your UDI R/C Drone can't hover and tilts to one side, it might be due to improper calibration (refer to the Calibration instructions). Another cause could be a seriously damaged propeller, which you should replace. Also, check if the motor holder is deformed after a violent crash and replace it if needed. If the gyroscope didn't reset after a serious crash, put the drone on flat ground for about 10 minutes or restart the drone to calibrate again. Finally, the motor itself could be damaged, requiring replacement.
