I could use some help resolving stability issues while in loiter. I set up my heavy quad using Auto Tune. While trying to test Loiter stability my quad started to loose control. I tried to keep it in Loiter as much as possible. When it began to loose control i would switch it to Alt Hold and it would settle down. Once control would return i would return it to Loiter. I am not to familiar with reading logs (I don't know what I'm looking at). If any one can tell by reviewing the Log I would appreciate any help you can offer.

That's usually due to poor magnetometer calibration. Have you double-checked that?
Chris,
Thanks for the reply. Yes, I have checked it. I spent about 10 minutes spinning in circles trying to fill the globe up with reference points to calibrate the compass. I was quite dizzy. LOL. It is also oriented in the correct direction. Both Scott Penrose and I have built Quads using the U8 Tiger motors and we are both having stability issues.
