Slow left rotation

After a week of not flying the IRIS I fired it up today with just my transmitter no ground station and it wanted to keep pirouetting to the left as though I was giving it left rudder. My trim is in the same neutral point I have been at for a while. I did not have a GCS setup but I did plug my IRIS in and download the attached log.

The logs when I export as a KMZ look appropriate in Google earth but do not play on my two pc’s in mission planner.

Any ideas?

I guess you should proceed with the accel calibration, compass calibration and radio calibration on your IRIS. Also, ESC calibration may be required. Use this useful wiki information and videos: … -hardware/ … esc-motor/
