SM Pitot for Ardupilot

thingiverse

This pitot was tested in flight with Ardupilot:Plane V3.9.8 (Pixhawk) on an ASW28 glider with a 4 meter wingspan, and did not give any problems. It is imperative to print it correctly, the internal channels must be free from any obstacle, any filament residues may compromise its proper functioning. I've designed three versions, use what seems most useful to your needs. Follow the Ardupilot guide for calibrating an airspeed sensor during flight: http://ardupilot.org/plane/docs/calibrating-an-airspeed-sensor.html On my ASW28 the ARSP_RATIO goes to 1.4 after the in flight calibration. Try it and leave me your feedback, thanks! Good luck! Simone Bonifazi and Marco Robustini
