It is a non issue.
Here is how to fly with restriction.
Since I have been flying HC-C2YK/F7666-4's with the same restriction I can tell
you it is no big deal. Going thru it or momentarily dwelling in it is not a
problem, even for metal props. It is continuous operation that's a problem.
So for operation you just avoid that RPM range. Take off, climb and cruise should
be well above 2300 rpm. If you want to cruise at 2300 RPM fine. In the pattern
when you get it slowed down and go to high RPM, your RPM in the pattern
should be around 1900 rpm to 2100 rpm. I don't think 2250 RPM is going to get
in the way.
First to explain there is a little history that needs to be explained. This
should make you feel better.
I hear good things about the RV 200RV, but you have to remember its a small company.
When Hartzell did there extensive testing of their props on RV's using
modified engines, electronic ignition and Hi Comp pistons a few years ago, they
found stronger modes or more vibration modes to avoid. RPM restrictions are
nothing new. The HC-C2YK/F7444 has a restriction on 180hp engines for many years
going back to the 70's (like on the Piper Arrow with this engine/prop combo).
When Hartzell said, wait there are differnt vibration modes, that are more severe
with the stronger power pulse when EI, HC pistons are used, WW jumped on
the bandwagon and copied or echoed Hartzells restrictions for electronic ignition
and Hi Comp pistons. The posted on their web site that Hartzell gound XYZ
so they where imposing the same restriction. I am sure at that point (about 2
years ago) they only where copying and had no actual data of their own. The kind
of testing Hartzell does is very sophisticated, expensive and time consuming.
(Note: There is a good reason for going with a big prop company.)
No offense to WW but I suspect they still have not independently flight tested
their props with strain gages. I could be wrong, but the restriction on Hratzells
is due to theoretical metal fatigue life. Since the WW is composite it should
not be fatigue critical.
Flying in the restricted RPM region will not cause catastrophic problems, even
for metal props, but from a theoretical total fatigue life calculation you are
reducing the life, which originally was assumed for practical purpose to be
almost infinite. Infinite is a very large finite number that is essentially for
practical purposes forever. Remember we are talking low stress but lots and
lots of cycles.
You know the paper clip trick bend it enough it breaks. Well if you don't bend
the clip at all or very little, it never breaks. Same with the prop. You keep
the stress below a threshold the life goes up to 10 to the 99th power. Over
a critical stress you do "fatigue damage". Fatigue damage is cumulative and adds
up (miners rule).
Therefore Hartzell limits blade life on highly modified engines (experimental
aircraft) to some where around 8,000-10,000 flight hours even with RPM restrictions.
They make some very conservative assumptions to get this number. Since
that is a lot of flying, chances are the blades will need to be retired due wear
before time. Also you have to remember there are huge factors of safety or
margins of safety and conservatism on these numbers. In other words even at 8,000
hour Hartzell on a radical engine is still safe, may be for another 8,000
hours. If you don't have HC pistons and EI than the prop life is not an issue
at all. It is essentially infinite.
WW is conservative, however its a mystery why a composite prop would have restricted
RPM, at least from fatigue life standpoint, since composites are not subject
to fatigue like metal. (I have a aerospace structural background).
I got the feeling the WW was being conservative and coping what Hartzell was
restricting. I think that is still the case. The WW200RV should be better than
a metal prop in vibration and fatigue, so I also suspect the 2250-2300 RPM
restriction is conservative. Their thinking is, hey it does not effect normal
operation and since Hartzell suggest it, lets do the same. No doubt the power
pulses are critical there for any prop and I guess they don't want to abuse their
prop either.
However when it comes to Props conservative is GOOD. The restriction is there
for fatigue life on metal props. WHY WW has a restriction I don't know for sure.
You would have to ask them. May be they did test it. Otherwise I think they
are coping the Big Boy (Hartzell).
So don't worry about it.
Give use a report on your new prop.

I am considering purchasing a Whirlwind 200RV prop to replace my Hartzell on
an IO360. I am looking for a weight reduction and elimination of the 2000 -
2250 RPM restriction. I talked to Whirlwind today and the rep mentioned that
the prop designer "recommends" avoiding 2250 - 2300 RPM and this is identified

Those of you using this prop, how are you handling this recommendation?

George,
Good post regarding the prop restrictions. A couple additional thoughts:
Regarding fatigue life, what you said is true for alloys of steel, but not
for aluminum. Even at low stresses, the fatigue life is not practically
infinite. Aluminum and its alloys are somewhat unique in this regard. I
haven't a clue what it would be for a prop, I suspect that there would be a
huge variation based upon usage and knick history.
Regarding the question of why an rpm limitation would be imposed on a
composite prop, I was under the impression that the Hartzell limitation was
somewhat based upon the crankshaft's interaction with the prop. Others more
knowledgable can comment.

I have the 200RV on my 7 with 32 hours. Thatis only a 50 rpm range. When
just cruising around I will use 2320 or 2200. Not an issue. Everything is
working great. The prop is very smooth.

I don't get the RVaitor ..... yet, so I can't comment on the article. I
don't understand how you can burn up the engine with those numbers.

You betcha! Remove the vernatherm, and use a sharpie to paint the cone
black. Re-install. Go fly (this is the best part! :-) ) and make sure
you get at least 1/2 hour flight time to make sure everythings at a
stabilized temperature. Land. Unfortunately we have to do that! :-( .
When things cool down, remove the vernatherm again. You should have a
nice shiny ring all the way around the cone where it contacted the hole
in the accessory case. No ring? Get a new Vernatherm.

Hi Jerry,
I usually run my O-320 powered RV6 at 2250 rpm with a Sensenich 79" prop and
get great economy as well as good speed -
like around 6 US gals per hour at 135 kts.. I too have been told to be
aware of burning up the engine, most notably the exhaust valves, as well as
glazing the bores. I don't really see how, as my CHT's are all around
310-315 deg F, and the engine is producing approx 55% power. I know we
didn't build our RVs to go slow, but it is relative, and the fuel savings
are nice.
Cheers

Or you can do what I did. Remove it, put it in some real hot water
(like boiling or slightly less than boiling) and see if it moves. You
can measure the end of it. Put it in cold water and it will shrink...
Worked great for me.
By the way, O-320's run real cold most of the time. My RV-4 runs real
cold all the time, in the summer I have a 3/4" hole going to the oil
cooler and I just get to 190F. In the winter I block it off completely
and it still won't get to 180F

Thanks for all your input on this issue. I made a typo in my original post. The
WW 200RV recommended restriction is 2050 - 2300, not 2250 - 2300. I'm flying
with a Hartzell now so I can fly around the restriction, I just would feel
more comfortable not having to.
In the specs section on the WW website it clearly states, "restrictions: none".
It's a little disappointing to read that then have the rep tell you the owners
manual states otherwise.

I'm always interested in how those low numbers are achieved. What fuel
flow, rpm & mp are you running to get those temps, & what's your cht? Is
yours rated at 150 or 160 hp? Oil cooler on firewall, back cyl baffle,

Inquiring minds (having owned several O-320's that ran hotter than that)
want to know.

I posted this back to the list because there's some good info others may
like ... but I'm going to do the 'do not archive' because it's probably
already there.

True on the surface. I'm in FL, and we don't have that problem!!! If
you're sure you have a good oil temp gauge, you might tape off portions
of the cooling air intake a little at a time to check in the frozen
nawth. In my experience, most cooling air intakes are too large anyway,
and they just add more cooling drag. The only way to know if your
inlets/outlets are sized correctly ios to do the manometer test .....
and you'll have to go to the archives to get that. It's involved.

Your theory is spot on. the only problem with Vernatherms is that they
stick when they get really old an abused.

Hey Mickey, Charlie, Barefoot Billy et al-
After a bunch of setbacks, interruptions, sidetrack, and minor crises, I'm
finally back at it with my -8. Today I cut my (new Todd's) canopy to fit
the fuselage. I've read about all I can find on the glued canopy subject.
Standing back and admiring how much the project looks like a plane when the
canopy is in place, I had an idea. Suppose I were to put a few dabs of
SikaFlex on the roll bar and canopy bow, carefully set the canopy in place
with adequate and competent help, and then add dabs of glue around the
periphery of the canopy once it was clamped to the spacers. Once it was
cured, I could cut the canopy from the windscreen and go to work on the
full-up glue job and filleting. What do you guys think? Am I missing
something here, or wouldn't this approach simplify the whole rigging aspect
of independently gluing separate pieces of plastic to separate structures
and hoping that they line up well?

Where can one buy Lycoming Parts on line? Did a Google search and not much
luck finding an outfit that can cross-reference old part numbers to new and
has a web site that you can order from.
It looks like I have to do it the old fashioned way, pick up the phone, and
call.
I did find what I was looking for. (Studs to mount a mag.) Want spares in
case I break one when I install my new P-Mags.
It appears that there is a lack of new Lycoming part vendors on the
internet. Wonder is it has anything to do with UnApproved Parts getting
into the system.

Gary,
I don't know about "online" but when I needed a bunch of new
engine parts a few years ago these guys seemed to be very knowledgeable and
had the best prices I could find at the time. I experienced all around good
service as well. Sorry I can't remember the name of the fellow I usually
talked to. They seemed to be willing to negotiate on some stuff like
cylinders at least. Premium Aircraft Parts

Gary,
Have you tried Sacramento Sky Ranch? http://www.sacskyranch.com/
<http://www.sacskyranch.com/>
Click on Lycoming on the left side and then search for "stud". It gives
part # description and price for a lot of studs.
I've never bought from them, but it looks like they have almost any part
you'll need.

==============================
Gary-
When I needed the short stud when I had my flirtation with the P-Mags last
year, I got them from Sacramento Skyranch. You can have the ones I got.
The only issue here is that you don't always know which P/N stud you
actually need. You may need to get an oversized (pitch diameter) stud if you
can't
develop the required torque at the required engagement in the accessory case.

When I was gluing on my canopy, I didn't have the F-821PP skin riveted
on, so your idea didn't occur to me. I did try to put some glue on
the canopy frame and set the canopy down on it, and it was a mess.
I didn't properly anticipate the exact locations on the frame where
the canopy would touch. Along the side, the location changes about
90 degrees from front to back. I ended up with a lot of glue in
places I didn't want it, so I had to have much larger fillets of
Sikaflex that I really needed.
I have done some test fitting of the windscreen to see how it will
line up, and I don't anticipate any real troubles, if that is
your major concern.
On my next canopy, here's how I'll do it:
Clamp the canopy to the frame, and use a bit of Sikaflex to
glue it on - don't try to do too much until the canopy is
glued to the frame. Once glued, then you can take your time
and run some pretty beads along the edges. I'd try to put
the glue on the bottom, not the top. You might need a very
small fillet on the top just for cosmetics. The initial
gluing step would require about 30 dabs of glue around
the frame.
Good luck!
