Nice Data! Looks like there are a few places where some parameters went awry but that is awesome!
I made a pic from your kml.

Yes,
For some reason the GPS lost his lock twice for a second or so... Maybe a bad cloudy day? Also the pressure sensor had bad readings for about a second, but this is nothing that can't be overcome.
If the weather stays fine today, I'll try to get some 50Hz data logged. This would be usefull as test data for some Matlab routines! Do you have matlab routines for your algorithms, Mitch?
As you can see, roll stabilization was more or less OK, but it some places the pitch angle showed +5 degrees where it should have been -10 degrees, which is not so good Fortunately, the angle solely calculated from the accelerometers was better!

I don't presently have a batch matlab routine that could process the data. Only bits and chunks as necessary to debug each part. That is a good idea. I have seen online a few basic matlab ekf routines written for exactly this purpose.
