Hi Netters.
A hot cabin is no fun. A friend did something about this when he built a
Jodel D-11. He acquired an automotive vent. This is probably from an old
model car. It was the kind that opened a hinged door into the wind. It was
often located in front of the car windshield and opened up into the wind. It
was manually actuated by a lever. He installed it at the top of his
windshield.
When you opened that little door up, ( approximately 3" x 5 ") you could
direst a hurricane of air at your self. It worked equally well on the ground
too as the wind blast from the prop hit it. Before any one gets too excited
about drag, there never seemed to be any penalty to airspeed when you
activated it. There was a good gasket around it's closed position. Rain
never entered. It was a simple arms reach to open/close it. His came off a
car but you could easily make one.
