|
On my RV-8A I transitioned the ¼” vent tubing to 3/8” about 6” before exiting the bottom of the fuselage. I also epoxied a piece of aluminum screen on the bevel end cut that faces into the wind. I read someplace that a few RVs had problems with mud dabbers plugging up the vent line. I’ll do the same on the RV-10.

I was in light icing on Sunday, coming back from the Cayman Islands, and that was the first thing that crossed my mine. I wasn't to worried about the wing, but that little cold soaked 1/4 vent tube, had my stomach in knots!

Well, I just got back from the hangar, and I'm embarrassed to say, but I didn't finish the vents before they were installed. Thy were not only straight cut but about an inch or more to long. They are standard now though, except for the right one, and I added a vent inside the faring just in case of an inadvertent icing encounter.We'll see how that works out on the next test flight. Just to low of a ceiling to fly today.
