Thanks guys, downloaded and flashed, will be flying soon 
^^^^^ This!This. Is. Beautiful.
Any changes after 4.0.0?
It's right there on your first image, EDTracker2_9150 4.0.0
And again I can't seem to get it calibrated properly, even after like 6 attempts. Will proceed later.
The red blobs show uncalibrated samples. The greenblobs show the calibrated samples.
