"May I ask how you water proof the pitot tube/airspeed sensor? Also if the plane is sealed what do you do about the barometer maintain correct altitude?"
"@Georacer
Ah ok. So then would varying inner diameters and tube length affect readings? I imagine so, but to what extent. The common digital airspeed sensor changes diameters twice (pitot tube ID -> flexible hosing ID -> board sensor ID)"
"Quick question: would the inside surface of a pitot tube affect readings? For example, a printed pitot tube (depending on print orientation) would be rough from the layer resolution."
