Engine Baffles, Part 2

It's funny how easy things seem when you're working with paper and cardboard.
What took only 8 hours to do in paper took more than 5 times that long in metal.
Still, I think they came out okay.

I am a little concerned, though, about the tiny opening left for the air to flow to the "high pressure" area of the cowl. In theory, this is how the other Corvair guys do theirs, except their cowl openings are round (about 5" in diameter). My little "teardrop" shaped openings are meant to improve the looks (in my opinion, of course), but I doubt the extra outboard sections will contribute very much to the cooling effort. Also, William Wynne swears that the alternator doesn't interfere with cooling, despite how it looks. I guess we'll just have to wait and see. Honestly, I'll be surprised if I don't have cooling issues. I may have to add more cooling inlets (like NACA scoops) on top of the cowling.

Total Time: 40.5 hrs.
