If you can post your version and any logs you can download from the APM I can help sort this for you.

Hi Jason, Thank you for taking a look. I have version 2.0.49 of the firmware on. My magnetometer is soldered on to the IMU. Attached are the logs that the APM collected.

Thanks

Ammar

It was cold as in around 40F and overcast skies. Not misty as such.. 

No I do not currently have a sonar on.. Will it make things better? How so?

Hey, Could anyone tell me what I could be doing wrong with Loiter mode? I want to try to put it again, this time after mounting a sonar (maybe). Though I am afraid it will shoot up again.. Any solution anyone??

BTW: I have definitely have GPS lock

sonar is accurate to within a few cm while the barometer is only accurate to within a few feet. I would suggest getting a sonar but that may not be the actual problem.

Hi All,

So I tried loiter again with sonar on this time. I got good results for the first 30 seconds or so. And then I could see it rise up slowly. It did not shoot up like it did the last time around, but it rose up constantly and pretty high again. I had to turn it off and land it cautiously. Could someone please help me with what could be happening? I am pretty clueless to be honest.

Attached are the logs from the flight.

Thank you!
