daveb Posted June 23, 2009 Share Posted June 23, 2009 Does anyone know where I might get one of these NACA air scoops or something similar? (There is a reference in the 1986 Cozy Newsletter which I've followed up but I'm not expecting any left overs) Many thanks Quote Dave VH-JZE Link to comment Share on other sites More sharing options...

longez360 Posted June 24, 2009 Share Posted June 24, 2009 Dave, I had 2 of these and sold them to another builder. They really didn't seal as well as I hoped. Consider just adding a good quality eyeball vent to the back of your plans naca vent.

longezdave Posted June 24, 2009 Share Posted June 24, 2009 Van's sells prefab NACA inlets for cockpit ventilation. I used one for my passenger compartment - http://www.vansaircraft.com/cgi-bin/catalog.cgi?ident=1245805475-118-618&browse=heatvent&product=ventilation-components Quote Dave Adams Long EZ N83DT Race 83 Link to comment Share on other sites More sharing options...
daveb Posted June 25, 2009 Author Share Posted June 25, 2009 I tried Aytons before posting and no reply from him so far. I have a NACA currently sitting in front of me which is great in summer. It has a little door hinge that leaks badly (see pic). So I pulled it off and use a block of foam as suggested I think in the plans. The issue, apart from the cold air leaking is that the vent obsures the top of the A/H graduation marks from my sitting position (which is a bit higher than the photo suggests) and I really need it clear for practicing instrument work. Its seems such a minor problem to ask guys who build whole planes yet its a difficult one to work out a simple solution for. I was thinking one of those Ayton vents cut back a little with a bit of silicone to help the seal would be the ticket. No room for an eyeball. (maybe I can give you a look sometime Wayne at YMNG?)
