My RC boat cannot move forward or backward or the speed is slowing down:

Please follow the steps for troubleshooting below:
1. Please check whether the battery is fully charged and insert the remote battery with the incorrect "+" & "-" polarity.
2. Check whether the propellers or driveshaft are stuck.
3. Check whether the guiding rudder is worn (if the guiding rudder is obviously worn, which may affect the speed of the ship)
