What do you think about small holes in canopies for ventillation? I see lots of planes with canopies fogged up inside. I tried small 1/32 holes on the front and rear of mine but they still fog up.

I never thought about it until my canopy fogged up. I think if you drill a small hole in the underside of your cockpit allowing it to vent to outside humidity it will equilize and reduce the fogging.
