I looked on this forum and I didn’t see anybody with the same issue.
My APM copter flies great in ALT HOLD, STABILIZE, SIMPLE, etc. However, when I turn on LOITER, it will sit for about 1 or 2 seconds making minor corrections, and then flies away like it’s getting paid to do so! It doesn’t always go in the same direction…usually random. At this point I have to take it out of LOITER mode because it won’t really respond to my stick inputs.
I’ve tried two different GPS units: UBLOX NEO 6M, and currently UBLOX LEA-6H with external compass. Everything is calibrated properly. I tested the compass through Mission Planner and the result was well within the acceptable level of electrical interference (<3%).
I let the copter sit outside for about 5 minutes. Got 11 satellites, with HDOP around 1.3 or something like that.
Any input would be greatly appreciated as I’ve already run out of hair to pull from my head!
@Post GPS Fly Away,
What ArduCopter firmware are you using?
This might be a firmware issue and not a hardware issue.
I suggest that you provide tlogs and/or data flash logs of this issue to help with troubleshooting it.

Thanks for the quick response.
I’m using the latest, which I believe is V3.1.5. I will try to get in a flight after work tomorrow and upload the logs. In the meantime, How much PID tuning should I expect to do for the GPS? I’ve already cut most of the values down by 50% and it seems a little better, but is this something that I should have to do?
