I was staring at work that needs to be done and my N12AY was setting in the
corner
of the shop and I noticed something I missed on ventilation exhaust.
The two curvy slots for the flap exit could easily have a small ramp added to it
to draw air out of these slots. I'm wondering if that would be a reasonable
experiment to do in the future. The flaps are about 1/8 inch from the upper
surface to the fuselage on 12AY but the bottom is slightly wider and of course
as the flaps extend the gap between fuselage and flap increases further.
Just another tweak in my life. Maybe I'll do that this fall.
Best Regards,
Bud Yerly

Yes, fancy way of describing noise and padding out the content with exciting and
conversational inspiring fodder :)
Fully agree with all Bud's points. Somebody at the beginning mentioned a
reversed
naca vent arrangement so that's what got reviewed but other exhaust arrangements
can be played with at some later stage. At this point it has been established
that providing a cabin exhaust vent to the outside improves flow through
capacity of cabin ventilation. Belly mounted exhaust vents downstream of the
rear cabin wall along with a vent at the wall is probably a suitable position
as the air flow is already a bit dirty from the cowling shape and mono
undercarriage
and would assist sucking out any undesirable vapor or smoke should that
arise.
