Drone cannot take off, strange sound appears

Dear all,

Today, I upload a stable version of PX4 firmware (ArduCopter-v2.px4 2016-02-24 14:27 643k) from http://firmware.ardupilot.org/Copter/latest/PX4-quad/

When I try to take off the Drone, 1 strange sound appears and drone ignores the 'take-off' command

I upload this sound on Youtube:

Dose anyone know about this problem? Please support me to fix it

Thank you very much

Anh

  • Thank you Joe,

    You are right, this sound is exactly about energy problem. In my case, I make a mistake when doing calibration

    I should choose "NONE" option, instead of Px4 power module (I used a different type) like the attached photo

    My problem is fixed, once again, thank you very much

    Regards,
