Hey Chris,
I'll look again at how the horizon is rendered when the plane is upside down. Thanks.
I'll think about the idea of interpolating data between the events that MGL saves. Will need to go on the back burner for now - I'm busy getting a release ready that will support Dynon Skyview devices. MGL records events at most every one second. Even then some seconds are skipped (the devices' processor can't keep up, and it's busy doing higher priority tasks). Interestingly most of the Dynon data logs I've seen capture 10 events per second. So that rendering will be much smoother right out of the box.
