I took my doors off one year, ten minutes flying and I couldn't wait to put them
back on. Noisy, windy, scary, just not for me. Could not get over the open door
fear factor ... Oddly I have flow in an OH-6 helicopter multiple times with no
doors and felt no fear ... Maybe it's just cause the Oh-6 makes you fearless ...
Anyway I don't like my Kitfox without the doors securely closed.
I use the snap vents in the bubble doors, they work very well for inflight
cooling.
