Hi...I received my new Vision 2 + yesterday. Very excitedly I unpacked and set everything up. I charged the batteries and downloaded the app to my I-phone. Everything powered up beautifully, the compass calibration was easy and the camera was operational. Thinking I was ready to fly I went to the back yard. I powered up and immediately I knew something was wrong. Immediately after powering up the front left arm light started flashing red accompanied by a alarm in sequence with the red flashing light. When I asked the machine to power up the other three motors did bid not the front right one. Everything else works fine except for that motor and I cant't find any help online. Can anyone help me out?
