I have an issue with a new quad running Pixhawk.
Upon taking off this morning, the quad immediately started to yaw in circles while hovering. The yawing stopped after roughly 10-15 seconds and then flew perfectly. I have noticed in one prior flight that the copter decided to do a 180 about face by itself. This must be a calibration/compass issue, as the log suggests.
Any ideas? I calibrated inside my home, so could that be it? Controller issue?
The logs will show you how crazy it went. When it stopped, it flew picture perfect thereafter.
Here is a video of my setup and flight this morning (disregard the battery failsafe sound, it was way too conservative).
