That's why my system uses 2 $35 pressure gauges: They are internally compensated for temperature and other factors, and outputs a 14 bits signal, with a full range corresponding to a 250 km/h dynamic pressure.

That's the price to pay to be below 1% at 70 km/h... And in practice it works...

The pitch string is corresponding to the instrument... But the string is very sensitive to sideslip...

Excellent, looks like a great plan and paper to read.

Are you going to put the design up on github?

Put me down for #2.
