I this plane a tail dragger?
If so did yo calibrate the compass with a 20 litre oil drum under the tail wheel?
You need to align the I craft with a calibrated compass, then lift the tail and slip the drum under, recheck with compass then hit the button.
Another thing, I have seen several AoA and pitot tubes the wrong way around. The AoA port will give you an airspeed, albeit inaccurate, but the AoA is never going to be right.
Add the above to the static leaks and for that matter doing a GPS box to determine if the calculated indicated TAS is within 2 knots of your actual TAS.
After all that......it can't possibly be wrong
Dynon Magnetic calibration
My Dynon D1000 ADHRS is in the middle of the fuselage on the lower longeron. I had the same scenario where I could not get a good bearing. I found the problem to be one of the long screws that secures the serial port to the ADHS to be MAGNETIZED?????????????? (You could pick up a screw with it... Duh!) I replaced it and secured the ADHRS to the frame using brass nuts, bolts and washers.
