Carl,
I am with you on the cabin air vents. Would like to know where he got them from.
He got them here:
Airflow Enhancement Kit [
planeplastics.com].
Aircraft Spruce sells them a bit cheaper.
They're made by
VenTube [
ventube.com].
In addition to the two cabin openings, they provide a third that mounts in place of an inspection panel in the tailcone. The third vent acts as an exhaust for whatever air flows out of the cabin vents into the fuselage.
