    First thing are you arming the apm to try the motors after calibration. Also I had a problem with china hobbypower esc that would not work. I had to flash them with simonk firmware. I did get them to work without flashing them by plugging in the apm to the computer then plugging in the lipo after the apm booted and then they would work.

      If you're asking if the motors run right after calibration, then yes. But once I unplug and plug the battery back in they stop responding. I reran the Wizard in Mission Planner, and the Mission planner just says Disarmed no other info than that.

        Take the props off. Plug in the usb cable. When the apm boots up then plug in your lipo battery. Arm the motors with your radio and watch the display and listen for mission planner to say armed. Then try throotling up.

          I did what you said and then I tried something I'd noticed on some threads, where people are talking about throttling down and to the right  to arm the quad. I tried that and it worked! 

          But now as soon as I leave it idle it disarms so I'm worried if that'll happen midflight. 

          The propellers spun but I wasn't able to take off. Maybe my battery needs recharging. Also my propellers are spinning in the wrong direction. I corrected that by flipping the props but the quad didn't take off so I'm going to try to charge the battery first. 

          I have a 3DR Quad C frame and I have ESCs and ESC instructions for the Quad D frame. Maybe that's why the props are turning the wrong direction.I gotta check that too.

            It is normal for it to disarm if you dont leave the ground after a certian amount of time. Make sure to have the motors spining in the correct direction and the props facing the correct way. Make sure you go to the setup page to set the motors correct.
