I'm just fishing for some thoughts on cockpit ventilation.
I am building an S7 with the bubble doors, so I am loathe to cut into the plexi for vents. When I did the demo flight with John McBean, just propping the door open with the door latch seemed to work well, so I had been thinking I would take a "wait and see" approach to adding NACA ducts.
I am having second thoughts about that approach as I would hate to deal with the mess and paint touch up later.
I am considering using a smaller than normal NACA duct with 1-1/2 inch SCAT tubing to eyeball vents in the panel.
I guess I am looking for some experience based input as to whether this will be adequate, inadequate or the whole thing is unnecessary. Thoughts?
