Question Why don't Carbon Cubs have internal ventilation?

[Neal]

This applies to more than Carbon Cubs but I think someone like CubCrafters would figure something like this out and innovate better cooling in planes like this. I have the four snapvents in my skylight and even with that, it's too hot to fly in the heat of summer with heat and humidity here in VA, for me! I had amazing air conditioning in the A-10 but the vents it had such as found in Cirrus and others sure would be nice in the Carbon Cub. Imagine cowls designed to have some airflow that enters ducting that comes through the left and right side of the panel or underneath the panel that you can open/close or adjust as needed. It would be nice to have some ram air flow into the cockpit. They do well for heating, why hasn't anyone considered cooling?

They do well for heating, why hasn't anyone considered cooling?

Probably because they are based in Washington state.

I have thought, several times, of connecting the front and rear heating ducts directly to the NACA inlet, bypassing the exhaust muffs.

The only reason I have not done that is that I don't know how the muffs would handle the heat with no flow. I suppose I could completely remove the muffs.

I spent a few thousand hours flying sailplanes in Western USA. The only way to keep tolerably cool at low altitude was to always have a wet towel round the neck. Evaporative cooling works well with the typical low humidity but maybe not so well on the East coast.
