Hello!
Using the AMP 2.6 with the uBlox GPS and with newest firmware, I encountered a strange behaviour in RTL flight. Starting with stabilize mode (yellow) I switched to RTL. (blue) On purpose I left it that way, because I had encountered that strange circling behayiour beforehand.
Compass and AMP where calibrated properly and the stabilize flight mode runs very good.
The starting point was on the top right position of the yellow line. GPS lock was achieved.
Does anyone have an Idea what the Problem is?
Thanks in advance

I had the same yesterday! Was flying around in Stabilize, hanging around using Loiter and hit RTL when the quad turned homeward and began its steady pace to the takeoff GPS location. It hovered at 10m for 5 sec, descended and landed like the Curiosity on Mars, smooth and precise.
Amazed by this technological feat, I decided to try the exact same thing again. The quad began accelerating too fast toward home and when it more or less arrived there, it started TBE'ing faster and faster out of control. It reminded me of the spectacle it performed earlier this year so I quickly switched back to Stabilize and landed by hand.
I had done compassmot earlier, but what amazes me is that during two runs, the first one was executed perfectly and the second one it went out of control (again). My friend's TBS Discovery with a Naza-M was loitering steady as a rock next to it the whole time. I think ArduCopter should use the IMU to correct its Auto behaviour as it is too unpredictable.
How do you create the above picture from google earth? I know you have to do something with the logs and an export or something like that.
Thanks
Have you done compassmot?
As usual, if you haven't, go through each step in Randy's excellent Arducopter 3.0 pre-flight and maiden-flight videos on youtube.
