Default NACA Vents

Iím just finishing up my tailcone with wings coming in January.

For those that have use a NACA vent to provide an air inlet for the overhead console, would you recommend installing them at this stage. My assumption is that it would be much easy cutting the holes prior to riveting the tailcone together.

My second question is has there been consensus on the best location to place the vents yet?

Iím also just starting to start looking at NACA sources. Vanís has one for $6.25 and ACS has several, but all are over $30. I was caught off guard by the price differences. There canít be that much difference in quality.

Thanks,

Bob

Smile Naca Vents

There's a huge disparity in the NACA Vents available. The plastic one's that come with Vans kit are, probably, ok in warmer climates and low altitudes. Using RPV does prove to be helpful. After a year + of my wife flying with blankets and towels I finally stepped to the plate and ordered the machined aluminum vent from Vans. Close to $300 but well worth it. Happy wives make happy flights!

Default NACA side of fuselage vent?

I first ordered from ACS and paid about $30 ea for 2 part vents. Sent them back and bought from Van's got 1 part vents and am really pleased. Just like already said, you do need good eyeball vents to control the air. Stein has a great deal on these around $100 ea.

Talk about resurrecting an old thread but I've been pondering the exact same questions that Bob had at this point in his build. The replys don't fully answer the questions. I'm about to rivet the tailcone and was wondering about cutting the vents prior to doing so. I too am planning on an overhead console. If so, where do you locate them precisely and what vents should I buy??

Good question, I'm at the same point.

At the very least it would be nice to know where to mask the inside skin prior to priming so that the Proseal will bond better.

A review of RV-10 images on Google will tell you where many people locate them. Looks like the middle of the bay just behind the baggage compartment at about the same vertical distance from the longeron as the front vents.

That's where mine are, but I can't verify that they actually work there. ;-)

I have read several reports that they work well in the above mentioned location. I am only adding one, and that's where its going. To be a little more precise:

As for when to cut it in. After the tail cone join, and before putting the top skin in there is plenty of access to get the job done easily

I cut mine and attached the vent (I only have one) after I had joined the tailcone to the fuse but before that last tailcone top skin was riveted on.

Thanks Leo. I know some builders have added one to each side. Is there a particular reason why you've decided to use one as opposed to two? Where did you source your vents? Are they standard sizes?
