I took the Inspire out for an early morning flight this morning to get the sunrise at Lake Erie near where I live. I'm guessing I've had about 80+ flights at this point, so not my first time. I was launching from a pier that was mostly concrete. It had metal sides and when I was near the one side of the pier I got a compass warning. So, I moved to the center of the pier and the error went away. Had good GPS lock and the safe to fly status. I used the auto launch and soon as she got off the ground she started to drift pretty good. I was not too far from some small trees, so I decided to get some height. It kind of was doing what it used to do a few firmware updates ago where it would do the whole circling the drain, but this time the drain was like 30-50ft wide. I had to put a ton of stick into it to offset what the Inspire was doing on it's own. Once I got up to about 50 ft it all cleared up and the rest of the 10-13 minute flight was uneventful. I did not get near or try to land on the pier. I landed in a nearby parking lot and had no other issues. I launched two more times from that same parking lot. I did not look at my MOD values, but will from now on. I don't think this has anything to do with the latest firmware. I'm sure it had everything to do from launching from an area that had too much metal in it. This is more of a warning or note to other's not to do this. I got lucky and was able to get it under control.
