I’m 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 local to place the vents yet?  

   

I’m also just starting to start looking at NACA sources.  Van’s has one for $6.25 and ACS has several, but all are over $30.   I  was caught off guard by the price differences.   There can’t be that much difference in quality.  

   

Thanks,

Bob:



I bought the ones from Vans'. Order them when you need something else. I 

waited until I had the top on to cut the holes. Made up a template of 

the NACA hole before I installed the forward vents. Then just traced it 

on the skin and used a nibbler to remove the majority of the aluminum. 

File to do the rest. I placed the front of the vent 10 inches behind the 

rivet line of the bulkhead, centered in between the longerons. No 

science involved. On accuracy's web site there is a reference to them 

working well. You can wait until later to install them as the top skin 

will be off until you are ready.



I have more pics if you need them.

Thanks for the quick response.   The picture was very helpful.



I'm assuming that the tray attached to the bulkhead is for your ahrs?



Out of curiosity, what's installed below the naca vent on the left side?



I know the feeling about your day job getting in your way.   I took today

and tomorrow off to work on the tailcone and I've already received a half

dozen calls from the office.   Time to unplug the phone in the garage. :^)

It's the power supply for the strobes.  Whelen (sp?) .   Vans has a 

plate that will let you attach it to the stringers.

Bob,  

      I am on the road so this is the only photo I have available. We placed ours just behind the baggage bulkhead. Again no science, just the shortest distance and it's the same place one of the very first OH console installers placed his with good results.  

      We waited till late in the build to add the vents but well before the canopy was attached. Wait... The canopy still isn't attached. Darn.  

      If you want to see some detail of our OH console visit: http://www.painttheweb.com/rv-10/console.htm   

   

Good Luck,  

Robin

How much does the overhead console cost bare?  When you’re all done installing it with vents and eyeball lights how much does that run?

I don’t have all the pricing yet.  

   

To me cost is secondary.   My wife requires a ton of blowing air in her face when she flies.  If installing an overhead vent is what it takes, then that’s a mod that will be done regardless of price.   I almost had to install air conditioning, but she has since relented on that requirement.  

   

There two methods.  Several have used a Chevy SUV overhead console or you can get one from Accuracy Avionics. http://www.accuracyavionics.com/v1/fiberglassoptions.html

I spent roughly $1500. Came with all the lights and vents. Here's a web 

site.

I believe that price is with them installing all the vents, lights etc.  I got just the overhead with all the parts and it came to $1100 something.  I am at work and don't have the exact amount at hand.  I think the overhead unit without the lights and vents is just under $700.

I purchased the OH Console with all the parts installed for full price

and I also don't remember what the number was but I paid retail. I did

however negotiate for AA to include a set of window ring closeouts for

free with the console purchase. I didn't feel bad as their actual

manufacturing cost is minimal and I was buying their premium console.

Turns out I went with a painted inner canopy and will probably not use

the rings. But that is another story.

Also note that I waited 4+ weeks for delivery. Not sure what the lead

time is now. 

Here is the completed console:

We bought the whole kit, too. It would have been much cheaper without  

the lights, eyeball vents, and switches, but probably no net savings  

once you bought all that stuff. OTOH, you could pick the lights and  

switches you wanted.



We think we like the lights, but "we shall see" when it comes time to  

fly at night.

The vents are particularly nice. Nonetheless we would consider the  

bare plenum "next time". Tony at Accuracy may be rethinking the  

switches, I think.



Because we're mounting an antenna in the "DVD" area, we've cut in a  

couple more access hatches. We also "customized" the area in the  

front center to accept grommets for antennae. Turns out we're using  

those grommets for other wires because we didn't want to cut into the  

structural shell above the pilots' heads for GPS antennae.



Also, in order to fit our particular airplane, the plenum needed to  

be completely cut away and re-fitted in the area of the "joggle"  

between the thicker and thinner parts of the shell, and at the aft  

end we needed to cut off the flange.



We made a "plate" to extend the bulkhead and serve as a doubler for  

the SCAT tube fittings at the back of the baggage compartment. This  

allowed the corrugated panel to be cut away to fit around the plenum,  

and still be removable and replaceable. Photos available offline by  

email.



Installing NACA vents with the tail cone, but not the cabin top, in  

position was pretty easy. Nobody seems to know an ideal position, so  

we just copied what others have used with apparent success. We  

mounted them right behind the baggage area, and roughly midway  

between the longeron and stiffener.
