I get the "Warning motor overload" message when the Spark is on but the motors are Off.
Battery is now at around 25 percent, and ive got the error message several times when i turn on the power to the craft.

How can i get this message when the motors are off?
Is this a hardware fault or why is this happening?
Its a new Spark, ive flown it only one time and then i didnt get this message.

Hi, sir. Did you get the error message frequently? Please try to reboot the aircraft and see if the message gone. Also, you can try to flash the firmware through DJI Assistant 2. Thanks for your cooperation.
