DJI Phantom 2 Vision Plus Troubleshooting Tip

My first experience flying the Phantom 2 Vision Plus ended with some hard landings (crashes) but then when I simply did a calibration of the "IMU" things improved dramatically. That calibration wasn't part of the typical pre-flight recommendations so I thought I'd talk about it and save others the frustration and disappointment I initially experienced. Now I'm very happy with this quadcopter.
