ok, I'll do it
should be getting a 0-40"WC dP xmtr which I'll recal to 0-5"WC this week
get some small brass tubing, thinking it run into the plenum under a fan motor strut
experiment with the tube end to avoid a pitot tube effect I suppose

the atmospheric pressure sensor would not cal so I am waiting for its replacement
capacitive humidity sensor ok, eventually should have 'corrected' air data
