Rick,
Congratulations on completing Phase I!!!
I assume that you are bringing the RV-10 with you to OSH so you can steal
some of Deems' thunder. :^) Looks like we are going to have another bumper
crop of RV-10s again this year.
See you in a couple weeks....
Bob

You also need the 3/8" bender channel for the fuel lines.
Also, buy or borrow a GOOD QUALITY 37 degree flare tool.
There are a lot of crappy products out there.

Subject: | Re: High Oil temps |
Dick,
Can you fill us in...maybe with pictures, on what you mean about opening
the gap on the wrap around baffles. How did you loosen them without
them flapping, or what did you do? My CHT's are warmer in climb
on my new cylinders than the old. The new have tapered lower barrels,
and that meant that the wrap-around had an odd taper to it too. So,
I filled in the gap with RTV. I'm wondering about your opening the
gap, because maybe by my closing the gap that's where the added
heating is coming from. Would be nice to see what you did on
#1 and #6. I haven't switched back to Exxon Elite yet, so I
have been holding off doing anything drastic, as I think my temps
went down with that oil. I may have just tightened up things too
much though as when I put the new cylinders on I went to every
extreme getting the gaps sealed....maybe I just over did it.

Subject: | Re: High Oil temps |
Speaking of what you did there with the cowl opening, I did
a little playing a while back and although the data isn't
really good data, I do have a theory....
The standard Van's Louvres don't stick out at all. My thought
was that the fast moving air coming by the lower cowl was
keeping the boundary layer too tight to the existing louvres,
not giving the air inside any real good path to get out...
almost making a "wall of air". (of course it may be causing
a slight low pressure...it should, I'd think) So what I did
was to stick on with aluminum tape a couple of homemade vortex
generators in front of the louvres. My theory was it would
create a lower pressure disturbance and give the Van's
louvres a little help by creating some suction to pull
that warm air out. It isn't reliable measured data, but
I think I did see a decrease of a few...maybe up to 10
degrees. That kind of sounds like how the effect of James
McGrew's would be, too...I haven't seen photos but if he
put additional louvres (the normal raised kind) in front
of the Van's Louvres, maybe they would not only increase
the exit area, but decrease the pressure in that area to
assist getting rid of the cowl's internal hot air.
It was just a thought...not sure how valid.

Hey guys, Thx for all your info regarding the pitot ports and lines. I
decided to order the Cleveland ports.
For anyone who doesn't know, if you order parts from a vendor before
Airventure and just pick them up at the show, the Wisconsin sales tax is not
applicable. I'm not sure what % it even is, but since I have to convert to
Cnd dollars, it all helps.

Sales tax here should be 5%, plus most counties add another 1/2% or
give or take a quarter percent. So 5-6% total.

Subject: | RV-10 Fuel System Update |
Just so ya'll know, Van's has finally modified their fuel system.
Notice the changes in the lines and the location of the valve
(allowing more room for the SCAT hose). They also have a different
handle with a button to lock it in position. I don't know when they
make the change, but if your front tunnel cover for your fuse kit has
a round hole, you have the old version. If it has a non-round hole,
you have the new system. It's about time them made a change like
this. You will also notice the plans call for a bulkhead fitting in
the side of the tunnel where it connects to the seat area. I know a
lot of people have been doing this anyway, but Van's has finally
acknowledged that making a single solid line all the way from the
valve to the wing is very difficult. For those who haven't gotten to
this point yet, it might be work calling Van's and seeing if they can
get the modified parts (tunnel sides optional, maybe new valve support
bracket, and definitely new tunnel cover and parts that go with it
like the knob, button, valve extension, locking plate, etc.). I don't
have the plans in front of me, or I would include some part numbers.
If anybody is interested, I can try to make a list.

Rob,
Speaking as one who bends tubing for a living, I would recommend you look for benders
from Parker or Ridgid. Whit these you have more leverage, and you can place
one end in a vice so that you can make cleaner bends.
The bender shown (in the link above) is made of cast aluminum and they tend to
break.
On the flaring tool You can get a good one from ACS.
And good luck to you on your bending :o)

Brett

Subject: | Re: RV-10 Fuel System Update |
I believe the change happened around April 2008. I picked up my QB fuselage at
that time, and got a "hybrid": Mostly the old system, but some parts (like the
tunnel cover, new valve handle, instructions) were for the new setup. Vans asked
me which one I wanted, I said new, they sent the needed parts.
Note the valve is also slightly different - the handle is slightly thinner, and
has a thru hole, for the extension shaft. Likewise, the mounting bracket is not
the old one turned upside down, it's slightly different.
The hardest part of installing the new setup from scratch is getting the placement
of the new, lower mounting bracket right. There's a long lever arm on the
shaft extension, and it has to hit the hole in the cover.
The new handle locks - it has a "pull up to turn" feature. It also looks a whole
lot better than the old one!

I'll try to get a couple of pictures but won't be back at the airport until
after the weekend.
What I am trying to describe is the portion of the cylinder baffle below the
cylinder (where the cooling air exits) around the top portion of the
cylinder. This is the part of the baffle that small diameter rod or safety
wire goes through on the front of the front cyl and back of the back
cylinder on each side. To open them the rod is removed and bent tab is
rebent to make the opening a little bigger and a new hole drilled for the
rod.
This process was described in an old book by Ken Pazer "speed with
efficiency". He experimented with various size openings to minimize cooling
drag.
The idea is opening this exit channel allows more air to flow around that
cylinder, think of an individual cylinder cowl flap.
Did you replace your cylinders already?

Subject: | Re: High Oil temps |
Ahh, that makes sense. So you're giving maybe a higher volume of flow
through there, even though it all doesn't hit the fins....it may
encourage more free flowing. Interesting. Mine is sealed up
really tight down there....I even RTV'd the gaps to make sure the
exit was ONLY through the fins...maybe I need to look at that a
little.
Yes, I had the ECI cylinders affected by the A.D. that required
the repetitive inspections and pressure tests, and at the time
they had a really good deal to just swap yours out for new ones
that weren't affected. I couldn't resist, since I had almost
400 hours on them already. I figured I could eliminate the
A.D. / S.B. worries and future possible headaches and just get
a new improved set. Turns out it was great timing because once
the economy tanked they withdrew the offer, so I was lucky to
get them when I did. It was a good learning experience to
change them all too...I feel much more comfortable working
on the engine.
