| Subject: | Looking for Engine Primer |
In my case it was an unfamiliar airplane. The master had a key switch as
well as a toggle and one of them wasn't on. Just don't forget to turn on
the switch as the engine won't start without it. Then when you turn it on,
there may be left over fuel that ran out of the updraft carb.

I agree with the fire hazard. However, this can be mininmized by only
pumping with care once the engine is cranking. The prinmer goes directly
into the cylinder, rather than the induction system.

I don't know about yours or all carbs, but I started one on fire this way.
The updraft carb allowed the fuel to run out when it didn't start right off.
Then when it did, it lit the fuel. You never saw two adults scramble out of
an airplane so fast.

I've started many times in the cold in my RV-6 and never have used the
primer. Two shots of the throttle while the engine is cranking does the
trick every time. If I were doing it over I wouldn't put a primer system
in.

| Subject: | Superior XP O-320 vs. 9A Cowl Interference - The End |
I've written about my efforts to get Superior to provide a shorter carb
to eliminate the interference with the 9A cowl. Here's the final
outcome.
Superior tested a shorter carb on two separate occasions and was unable
to get the test results within their specifications. Rather than wait
for another carb to be test, I elected to follow the advice of some on
this forum and purchase a scoop for an O-360 engine. Superior has
offered to pay for the scoop and is very apologetic. Apparently,
they've always used the same carb on their engines and hadn't
experienced a problem with fit until we tried putting them into the 9.
I've suggested to them that they notify all purchasers of the O-320 to
inform them that they will need the O-360 cowl. It is my understanding
that Superior will continue testing carburetors in hopes of finding an
acceptable substitute.
I received the scoop yesterday and bonded it to the cowl. The fit and
finish is very good, and the additional space should be more than
adequate to accommodate the FAB.
As a side note, Aerosport Power assembles the same engine with the
shorter carb. I can only speculate what this means.

Hello all. I'm very close to pulling the trigger on an RV-9A for my second
build project (a Sonex being the first). Just curious if there are any -9
builders and/or flyers in either middle TN or south central KY? I know Bob
by Hestor is right here in Hoptown with his -7. (Bobby - I want to come up
with Robert and Doug sometime to check out your -7!)=0A=0AThanks,=0A=0ARick

Rick,
There are several "9's" in the area. I know of one (Bob Perkins)
in Gallatin TN, two around exit 24 on I 24 (Jerry Vanetta and a friend).
I have visited Jerry at his house and he has his airplane in his hanger
on his property. His home is with several other airplane people along
side the grass strip. A nice place.
I'm building a "9-A" and I will be retiring in the Springfield
Tn area in about 2 years. I just riveted my front top skin on last
night. I'm doing a QB version Great airplane. Are you coming to
Sun-N-Fun this April? A great time to look over the many variations of
the "9". There will be a "9" there that is trying to qualify as a LSA.
It will have the O-235 and a basic VFR set-up. What a great idea!
Jim

You will pick up 3-4 mph top speed. Is that not enough?
Vibration comes for many things, old engine mounts,
mass balance in engine (crank, rods, pistons, accessory
section), power imbalance between cyl (one making more
power), Prop or spinner imbalance.
Also baffles or controls or any thing that can transfer the
engine vibrations to the cowl, engine mount or fire wall
will increase the vibration in the cockpit. Cables, hoses,
wire bundles can all do that if too short or tight.
If you have vibration because you prop is out of balance, than
yes you will be smoother, but the real JOY of the new prop is
the incredible efficiency. Hartzell MADE the BA prop for
YOU, for the RV-7.
I suggest you get Lord engine mounts (part J-9613-4). The
cheap ones Van sells suck.
Also the BA prop is a 2000 hr TBO and no AD's or SB prop.
Vibration? May be, but that is not a reason to change to the
BA. The BA is a way better prop for the RV. My suggestion
is use your C2YK prop as long as you can, sell when due
for overhaul/inspection than get the BA. If you plan on keeping
the RV7 for say the next 20 years than get the new prop. It will
pay for itself in lower maintenance and better speed. Too bad
the price just took a jump I noticed in Vans' catalog.
Hartzell REALLY wants you to convert becasue the new prop
has no issues. You may get $1500-$2000 for your old prop,
may be $2,500-$3,000 if low time late model? The new prop is
about $6,000. If you have $4000 burning a hole in your pocket
than it may be a good up-grade.
Do you plan on flying into gravel and mountain strips this
year. May be you should explore first than get the new prop?

Original post:
I am about to start the rudder for a scratch built 601XL (Corvair?).
However, yesterday I heard of a 3/4 completed Vision homebuilt that was
for sale. (The builder had died). This project is a composite plane
and total estimated time for a scratch build is 3000 hours. I have not
seen any estimates of how long a scratch build is for the 601. My
question is this? Has anyone worked on both metal and composite? What
are the advantages and disadvantages of each? I realize this is a
Zenith (metal built planes) site and that the people who are here have
decided that is the way to go. At 59, I suspect this will be the only
plane I'll have. I'm taking flying lessons now so I don't have a much
experience in that area either. I would assess my building skills as
well above average and have space and tools to build about anything. I
would just like to hear what others had considered when they chose their
project.

| Subject: | Re: Hartzell Blended Airfoil Prop |
Switching to the BA prop should make no difference in vibration if the
original prop is properly balanced. As far as speed goes, I asked this very
same question to one of the engineers at Hartzell about my Rocket prop and
his response was "The differences are small and I would not swap props
simply to get the additional performance, its not worth the cost in my
opinion."
The difference between the 8475D-4 prop and the 8068D BA blades suitable for
a Rocket was four pounds difference in thrust. The non-blended airfoil
props are already very efficient.
If you wanted to reduce vibration I would consider a three-blade MT prop.

| Subject: | Aircraft Painting 101 Video |
I just finished watching the Sam Jones video on Aircraft Painting 101 and
was making notes. There is a part where he talks about painting on graphics
over the base coat using Fine Line tape, but he doesn't say how long to
wait after putting on the base coat to starting on the graphics (ie stripes
and stuff).
How long should you wait before adding color graphics or stripes after
putting on the base coat?
Have a goodun!

The answer is, it depends.......
Since temperature and humidity varies, it will be different depending on
your circumstances.
I've heard horror stories from folks that finished up in the afternoon and
came back the next morning to finish trim. The tape left visible marks
because the paint wasn't totally cured.
I personally would wait 24-48 hours depending on weather conditions.
