Had my first crash yesterday. Complete user error as I flew the bird into my house and it then landed upside down on my deck (from about 8 feet up). I put new props on and it flys just as it used too. One of the motors, when looking at it from directly above appears to be just slightly off level. Maybe by only a millimeter. I then checked to make sure the props are level with each other. The one appears to be a millimeter or two off from the other. Is this something I need to worry about? The craft still flies great and for all I know the motor could have been off slightly even before the crash. The last thing I want to do is have long term problems because of one dumb crash.
