Fresh Air Vent
I recently purchased a flying RV-4 (and am building another one, just for giggles) that has no means of getting fresh air in with the canopy closed. I noticed in the November Kitplanes in an article by Paul Dye on his RV-3 canopy latch there was a Van's CA LV-3 near the canopy handle. Paul mentioned that it doesn't work well where it is currently located.
While most people don't think of the Pacific Northwet as a place where one needs over large amounts of fresh air it can get down right uncomfortable during those 2 weeks of summer we get. Why, some days it can hit almost 80degrees!
What have others found successful in getting fresh air into a -4, particularly in flight at lower altitides and airspeeds. Has anyone used the RV-12 style flat doors?
