Hello,

just finished building my X525 with APM2.5, and without PID Tunig it works already very nice. Stable, responsive, no wobble. 

The only headache: Loiter is a mess. The Quad instantly flies *somewhere*. Altitude hold works fine, but whenever I switch to Loiter, it rapidly flies away. 

Any idea, what this could be? After powering it on, it takes around 2mins to get GPS lock (blue LED stops blinking), then I fly around for a min, and then testing the loiter. 

Is there anything more to calibrate than the gyros? Something might be forgotten, to explain this behaviour?

Thanks,

Michael
