Hi Bob,
With the overhead console, I really don't think you need the side air
vents, or at least in my plane I wouldn't. The overheads in my plane
deliver a lot of air. With the side ones closed off it would also make
your interior work easier. The only consideration might be that the air
is blowing on or around the passengers head vs coming in from the side.
But I really don't think that's big deal. If I were doing it over I
might consider doing what you're thinking of.

Subject: Air vent question
For those that installed an overhead console with air vents:
What did you do with the standard rear seat vents? Are you happy
with your
decision?
If you removed the vent and permanently close the opening or you
left the
vent per plans , any regrets in doing so?
As you might surmise, I'm trying to decide what to do myself and
am looking
for other opinions and data points to help me make a decision.
At the
moment, I'm leaning towards removing the vent and permanently
closing the
opening. I think that the overhead vent will be able to deliver
ample air
via two new naca vents in the tailcone. I would also think this
would
minimize the chance for rain and other objects to come in through
the vents.
Thanks,
Bob

You can put them on at just about any time. I installed mine while I was still
fitting the canopy and the forward tailcone skin was still off, but I can see
how it could be done at any time by pulling the panels for the tailcone access.

You can put the naca vents in at any time. It isn't a big deal until the
canopy and the top skin of the tail cone are permanently installed. I
haven't cut the hole yet in my tail cone, but will most likely be doing it
right after I attach the tail cone to the fuselage.

What engine setting are people using ? My oil consumption seems to have
stabilized. So I'm backing off the high MP and RPM settings and looking
for that 'sweet spot'. So far it seems that the engine runs smoother @
2300 RPM and above, below that I seem to pick up some engine vibration
(probably need to get the prop balanced). What setting are folks using.
I'm still ROP and expect to stay that way for a while, So i'll wait for
the LOP discussion/s.

| Subject: | RV-10 Project For Sale: Tail+QB Wings + QB Fuse |
After much deliberation, I've decided to go ahead and sell my RV-10 project.
I've had very little time over the last 18 months to make much progress, and
due to work, it will probably be another 18-24 months before I can devote
any significant time. Rather than continue to live with airplane parts
filling in every room in the house until then, I'm putting the kit up for
sale.
I don't have any specific price in mind and I'm not in a rush, but anyone
interested is welcome to come see it or look through my photo gallery of the
build:
http://noimnotcrazy.com/gallery/
It was a QB Fuse+Wing, kit #40715. I did pull the floors out for inspection,
priming, and sound insulation, but otherwise is a stock build. Most pieces
were akzo primed, much of the tail was also alodined. Tailcone is attached.
The project is located in Southern California.
Anyone interested or have questions, feel free to contact me off list.
Best Regards,
Patrick

| Subject: | Re: Engine MP & RPM |
I've usually liked 2360RPM for most cruising, and interestingly
there are a handful of people who also found that to be a
smooth sweet spot. Might not work for everyone but it's
been working out great for me. Give it a shot and
see if you find it good too. I don't generally get below 2300,
and just use 2400-2500 for certain circumstances.
I do find that although 25 squared isn't a bad way to climb,
the engine stays cooler better for me if I keep it full
forward all the way up through 5-7k' for climbing. It gets
you out of the warm air faster.

Lately I've been staying at or right below 2400 (Tim's right on the

keep it at 2400ish and WOT at altitudes over 10,000. I have a power
chart I could scan that seems to right on with a stock IO-540, but you

| Subject: | Button Labeling For Infinity Stick Grips... |
Dear Listers,
I've been pondering for a while how to "label" the various button functions of
the Infinity stick grips I have wired up in the front and back of the RV-8. I
spent some time today with the 'ol CAD program making a caricature drawing of
the Infinity stick grip and buttons and adding some labeling. My plan is to
silk screen the attached layout right to the instrument panel in the front, and
to a small metal piece for the back. The cockpit and instrument panel will
be black, so the diagram should pop nicely on that background.
Just thought I'd pass on my efforts.

Best thing you can do to your engine, airframe, and instruments ....
well, the steam gauge kind. Have the prop balanced at your chosen
cruise RPM.
You might play with the mixture again when you throttle back to see if
it makes a difference with the vibration.

I filled mine in solid. In my opinion, while simple and efficient, they looked
tacky and "homemade", and made a nice finished interior sidewall difficult.
I am definitely doing an overhead panel and most likely air conditioning.

| Subject: | High Fuel Pressure - Extreme Rich |
Fired up today for our first short taxi test. The engine would not run over 1350
RPM WOT. Fuel pressure was 48 PSI. After shutting down we pulled the plugs,
they were all black, way black. Indicating the engine was very rich. The
air box had raw fuel in it. We have an Airflow Performance injection.
We didn't have this problem during our last test run. Since then we have performed
the service bulletin on the mags, I double checked the timing. I did not
try to lean the engine using mixture, I think the richness may be caused by the
excess fuel pressure, and not the actual mixture setting. I could be wrong
but I don't think the mixture would be that far off.
Any thoughts??

There is a service bulletin on the RSA fuel injection systems. I don't have
it here to get the numbers, but if I remember right, that is the failure
mod......you lose power. There is a screw on the side of the controller
that needs to be checked.....
Just an idea.

I use 2400 also and set the MP at level off based on the IO 540 chart
from Lyc, then lean.
I usually pull back to 2500 once safely airborne and climb with full
MP to level off, then roll back to 2400.

Linn has something there.
I saw curious vibrations at reduced MP only to later discover that MP

out once I followed the suggested RPM, MP and altitude chart.....

You gotta lean this engine on the ground. Sounds like you had it

Did it run right on the first runup (ie, confirm your tach is correct?)

He has AirFlow Perfomance injection, not RSA, so should not have that

| Subject: | Re: High Fuel Pressure - Extreme Rich |
Seemed to run OK on the first run up, we had normal fuel pressures around 30.
I understand the theory behind leaning while on the ground, but if the idle mixture
has been set correctly leaning on the ground is not required (for 'standard'
conditions). This is according to the folks at Airflow Performance. The
manual provided with our fuel controller goes through this procedure.
Leaning also does not explain the high fuel pressure......
Thanks, Jason
