You talked me into it. I built a 4.5 ft. plenum today using a foam core to mold it. Looks great and will deliver lots of cool air to front and back seats. Thanks for this thread.

I have the same vent system as Jim and it works great.  Blowing the air at your head is the most efficient means of cooling off.

I also have the 2 panel mounted outlets. The majority of the air out flow is via the spar area and the lower wing bolt holes.  I assume you have the reverse scoop covers on the bolt holes and they are aligned with the airflow for maximum suction.James F. Agnew

>>Don - I recommend having a couple extra vents on the panel fed from a NACA near the canard. In my air-leaky RG the overhead plenum provides all the air I would need, but it's concentrated. Having an extra vent for each front seater coming out of the panel allows you to fine tune your comfort. If I turn the front plenum vents full open I get so much air movement by my face that it activates the intercom constantly. My passengers don't need the extra drama of listening to my irregular breathing. Imagine having Darth Vader as a flight instructor. I wonder if the tighter cabin of a fixed gear would mean the plenum would allow in less air, making extra vents even more helpful. KentXLRG  On Aug 3, 2009, at 7:13 AM, Don Johnston wrote:
