I noticed the -4 on the EAA's web site Desktop Wall paper for march has 2 NACA vents in the canopy skirt. Does anyone on the list have a NACA vent installed in the canopy skirt just behind the pilot? I'd like to find out how well this works. Any other good suggestions for getting some air to the back? My wife will appreciate any suggestions.

This is not an original idea but my own cheap version of somthing I saw for sale for about $50. Parts: (1) 4" C-clamp - make sure it's about 1/2" bigger than an oil filter (1) 1/4" x 1.5" steel roll pin (3')1/4" ID tubing (1) hose clamps to fit 1/4" ID tube (1) 1/4" ID rubber washer To make: 1. grind a flat spot in the arch of the clamp behind the fixed pad of the c-clamp to allow drilling a 15/64" hole through the clamp pad. 2. grind the roll pin end to a very sharp point at about a 30deg angle. 3. Hammer the roll pin point first through the hole in the clamp until the point is about 1/4" through the pad. 4. Place the rubber washer over the sharp end of the roll pin 5. Clamp the 1/4" tube to the bottom of the roll pin. I tried this out last weekend, it took about 20 minutes to make the thing and it cost about $1 using an old c-clamp I had in the shop. It works perfect, by clamping it to the back of the filter it drains the oil out through the tube and keeps the oil off everything else.

One near the front edge of the canopy skirt for the pilot, and one just behind the pilot. Both are on the right side skirt. The one for the "pilot" doesn't provide any airflow at all. I never open it. Might have something to do with the fact that the canopy skirt angles toward the firwall just aft of the vent. The vent for the passenger works very well, but is a little on the noisy side when open. A friend with a -4 retrofitted an under the wing naca vent ala RV-8, and it works very well.

It surprised me that it stays there (it is a tight squeeze!)......if necessary, I suppose you could use some kind of "stickum" to hold it in place............Hope this helps.........CHEERS!!!!!............Gene Smith. ________________________________ Message 6 _____________________________________ Time: 11:36:34 AM PST US From: LessDragProd@aol.com Subject: RV4-List: Cockpit Air Outlet? --> RV4-List message posted by: LessDragProd@aol.com Hi All, I've read quite a bit about the air inlets. Where is the air outlet located? To have air "flow", it normally requires an inlet AND an outlet. Jim Ayers RV-3 N47RV PS I know I don't have an air outlet "designed into" my RV-3. Is it expected to just happen? ________________________________ Message 7 _____________________________________ Time: 12:21:16 PM PST US From: "Gene Smith" Subject: RV4-List: Air Outlets --> RV4-List message posted by: "Gene Smith" Yes, Jim Ayers you are correct......My canopy on the -4 is not that tight, and I purposely have not used weather stripping, caulking and etc. because of what Van said in the RVator about the smoke in the cockpit the first time he did an airshow after installing a smoke generator in the -4...I have always been concerned about carbon monoxide entering the cockpit, so I live with the built-in ventilation, but the exhaust system is checked for cracks every time the cowl comes off, and the bottom of the fuselage, and the firewall are totally sealed and checked often...............CHEERS!!!!!........................Gene Smith. ________________________________ Message 8 _____________________________________ Time: 12:32:38 PM PST US From: "Van Artsdalen, Scott" Subject: RE: RV4-List: NACA vent in canopy skirt --> RV4-List message posted by: "Van Artsdalen, Scott" I have mine mounted on my forward fuselage just under the cheek cowlings on either side. Makes for pretty decent airflow. -- Scott VanArtsdalen Network Manager Union Safe Deposit Bank 209-946-5116 -----Original Message----- From: 2 at UT [mailto:tomrv8@gvtc.com] Subject: Re: RV4-List: NACA vent in canopy skirt --> RV4-List message posted by: "2 at UT" Pat, I have two naca vents in the canopy skirt on my -4.

Total failure in each case -- no air entry to speak of. They do work well, however, if placed in the lower wing skin.
