Hello, After getting two Quadcopters for Christmas and after practicing inside, I wanted to go today in the sun and start flying. I was using the X5C-1 (rather than the mini) and had some crashes but on the landing skids. I was practicing turning and trying to get the copter back to me. The last time it crashed, it was upside down the the prop was working intermittently but not lifting the copter. I could spin the prop with my finger and it was able to spin as normal but I think not enough power for lift so I took it home and cleaned it up and re-calibrated it. After restart it stopped spinning altogether. I am not sure what else to do. Can anyone give me some advice what I should do next? Thank you for your time in reading my problem.
