REFLECTOR: O'head plenum vs. panel vents

[Keith Hallsten]

Chuck,

 

I find your view on the overhead vents vs. the panel vents really
interesting, as Rich Guerra has the opposite take on their relative value!
He advised that he hasn't opened his panel vents in years, since the
overhead vents do such a fine job!!  I'm still putting in both, and I will
see which I prefer when we get flying!

Dave,

My overhead drain line works and is well clear of the main gear travel, but
I had a leak in the lower area of that NACA so rain would leak into the
cabin until it got about 1/4" deep in the NACA and would reach the outlet of
the drain tube.  The first time it rained heavily and the plane set outside,
I opened to the door to find about an inch of water in the bath tub.
Fortunately, plastic carpet dries well and fiberglass doesn't rust, but know
this; a LOT of water flows through that NACA.  A lot of the roof area
constitutes the 'NACA drainage.'  An inch of rain will probably put 2"-4" of
rain water into that NACA, so if you you're letting it drain into the cabin,
I hope you have an equally big outlet drain.

 

I'm looking at putting a temporary aluminum plate over the overhead NACA and
using silastic to put it in place.  The front vents do a great job of
ventilating the cabin and I don't carry rear passengers that often and the
cold it lets in during the winter (through the plastic eyeballs) is most
unwelcome.  The only purpose the overhead plenum has served so far is being
a good wire run to the overhead LED cabin light I put in.  All things being
the same, it wouldn't hurt my feelings if the overhead NACA and plenum
weren't even there!

Hi Dave,

Thanks for the advice.  Sorry it happened to you.  I haven't run my drain
line yet, leaving it for last "finish" kind of stuff in the aft cabin.  I
have the XL-5 which is kind of a stationwagon set up back there, I have to
fab some kind of back deck fit even with the back seat backs once they are
in the folded position.  I consider myself duely warned on o'head drains.  

 

Thanks

Terry

By the way I got my broken leg XL back up into the air again yesterday.
It's been down since a bad trip home from OSH.   But all is well again.  Boy
it felt good to get it up.  

 

By the way, all those that haven't checked yet, make sure you check the main
pivot bolts on your RG aircraft that they are grade eight bolts.  If you
have a kit prier to 1999 they are grade five and should be changed.  The new
plans in the site shows that they are grade eight.  So if you are working
off the paper drawgs they are grade five.  

 

Also if you have the (V) shape air duct in the top of your cabin with the
water drain line coming out the back make sure it doesn't come close to your
retract system during up and down travel.  Mine did and the linkage caught
on it and hung up the right gear leg on landing and slammed it back up in
the well .  I then became a passenger out into the tall grass, two down one
up.   Just for a small peace of plastic has cost me a great deal of money
and time.  It's the little things that can bite you.  I have eliminated mine
completely now.  Let it drain into the bottom of the plane and drain out.
No big deal.  

 

Don't wait to check, do it now before your next flight.  This should be a
mandatory inspection on all RG Velocity aircraft.  Both items, grade eight
bolt and water drain line. NOW

Dave
