I have a question to you people flying about cabin ventilation. I have 2 eyeball vents on the panel for air intake
but haven't provided any vent for exhausting cabin air. In an exhaust vent necessary or does the opening where
the elevator passes through the rear fuselage act as an exhaust vent?

Al,
I think there are many unsealed holes in our planes, unless you build a pressurized cabin. In my TR-1 I stop the cold air from coming in past the flap handle by opening the cabin heat valve. Even with the vents closed the cold air enters , low pressure area. I doubt you would need to add any additional exhaust vents.

Mine has no exhaust vent so I guess the opening works just fine.
I have been debating about making a good seal on the rear bulkhead panel so I can use that area as a good place to put an outside air temperature sensor, but now that you bring this up I may just leave it as it is.

There are enough leaks that you don’t need anything specific

I put my OAT sensor in the aft portion of the wing root fairing. Seems to work fine.

Hello Al, My experience is that there is a significant flow of air (cold in the winter) that arrives from the rear of the airplane into the cockpit area when the eyeball vents are closed off.
Probably comes in around the opening in the fuselage tail where the elevator spar goes through. I have not yet come up with a practical means of blocking off this forward flowing cold air.
No problem with air flow coming into the cockpit through the eyeball vents when they are open during the summer.
