    In Texas the eye ball vents are useless, I've started cracking the doors open and use a Velcro strap to hold it in position. Plenty of airflow, and no modifications.

    I bought a set of the Vista vents to put in my doors. I flew in a plane that had them before and was impressed with them. But as mentioned, I am nervous about cutting the holes. I'm going to wait for it to get good and warm out before I attempt it.

    Paul, just curious if you have low flow or just low velocity thru your eyeball vents?

    This might work for some. I used it to force air through a cabin heater. The down side of that idea is that all air through the heater was ambient outside air. Recirc. is a lot better for heat. It might work for an eyeball vent. I made it by shaping a piece of foam, covering it with glass, then digging out the foam. One could be made for each side on the smooth cowl shaped to fit. It is also something that could be made later. The only mod would be to cut holes for the scat tubing through the firewall and instrument panel. It could be designed with a fairly straight run, with minimal internal friction.

    When its warm I leave off the "cuff" that covers the wing (front spar) to windshield junction. Gives me a nice breeze. If it is too warm for that I fly with the doors off. Haven't had a problem with hot feet or legs.

    I bought a set of NACA vents from Van's and they work great. I live in the deep south. They are put in about where Phil's are. I used the cheap black plastic eyeball vents that came with them. To connect them I just bought some heater hose at NAPA that would allow a slip fit. The eyeball just butts up to the NACA inlet. No ducting at all.

    I would do it again but I might spring for some better eyeballs.

    YMMV

    Flying in the Houston area is just "hot!" My solution is to replace the little door knob for a 3D printed knob that allows me to crack open the door about 1". Cruising ~100 mph, the doors are rock solid and the cabin is so much cooler.

    I'm going to Post the *.stl files in Facebook/3D Airplane parts. These are not bling, but for less than $0.50 each I cannot complain.
