I would recommend you check the sump and see if the orifice is cut for an
0-320 or an 0-360. It sound to me like the engine is starving for air. The
0-320 sump can be used on an 0-360 but the orifice leading to the manifold
from the carb or fuel injection must be honed out to the bigger size used
by the 0-360.

--> RV-List message posted by: Bill Dube <bdube@al.noaa.gov>
Well, after a few delays, including learning how to use the latest
printed circuit board (PCB) design software, the prototype LED position
lights are complete and working perfectly. I tested the finished units and
they put out more than enough light in all directions to meet FAA specs.
Here is a link to the write-up with some pictures:
<http://www.KillaCycle.com/Lights.htm>
The prototype board is designed to lay flat against the aft wall
of the Vans sheared tip interior space. It's important to note that the
actual physical lay-out of the components is quite fluid. That is, as long
as each of the LEDs is pointing in the direction it needs to, it is
possible to move any of the components wherever you would like or re-shape
the board completely.
The next iteration of current regulator PCBs will be considerably
more compact. I thought I might need de-coupling capacitors, so I put in
pads for them on the prototype PCBs. However, the circuit works fine
without them so I will eliminate the pads (and the space they occupy) on
the next design iteration.

Another reason to consider the Sensenich if you decide to go with a
fixed pitch instead of C/S prop is that the Sensenich can be easily
repitched if necessary. Some wood prop makers claim to be able to
repitch their props, but material must be removed in order to make
alterations to those props.
I considered a wood prop for my RV-6, but the repitching thing (I
started out with a 150hp engine and knew it would eventually be rebuilt
as a 160hp) along with the need for periodic retorquing of prop bolts
caused me to settle with the Sensenich. It turned out to be a very good
decision.

Two questions:
1) Why are you under the impression a Sensenich fixed pitch prop can't
be installed on a modified engine?
2) What is a modified engine??

Bill, good work!
I already have Aeroflash tip position & stobes that I paid dearly for - but
I also want to run my IFR RV-6 with all electric engine (efi, ignition) on a
35 amp alternator, so am looking for "load shedding" components.
Put me down for a set.
We ought to be able to do a "replacement in lieu of" for the incandescent
bulbs in the Whelen and Aeroflash tip units.
How about "low current" landing and taxi lights next (to replace Halogen 50
or 100 watt bulbs) - that will be a good "load shedder" for the peak
current portion of flight - night IFR approaches & landings.

--> RV-List message posted by: "John" <n1cxo320@salidaco.com>
Just for my own enlightment, can someone tell me why --- a pilot landing at
the RMRFI with an airplane with a Subaru engine with a turbo powering it had
to do a go-around, and I hear used full throttle with the turbo "on" and
reportedly "blew" the engine...made a good landing after getting radiator
coolant in the face, and reports said the engine was damaged.
Why would that occur? Turbos on that engine in a auto take full throttle
routinely I believe; would the possibility of overspeed with a propeller as
the load be the cause? Thoughts?

John:
It's impossible to say without more information. Assuming that the
turbocharger was in any way related--which it may well not have been--the most
likely explanation is probably that the system used to prevent over-boosting
the engine failed. There are several different ways boost can be limited with
a turbo installation, including manual control.
It's a popular misconception that turbos are "on" or "off." Generally
speaking, a turbocharger runs continuously when the engine is operating.
However, its response curve is non-linear, so that it has a much larger effect
under some operating conditions than under others. This gives rise to the idea
that the turbocharger "comes on" at a certain point.
Or, in the words of former world driving champion James Hunt, "The first thing
that happens is nothing, and the next thing that happens is everything."

I think the position lights are neat too. What about a landing light with
leds? Is it possible to get enough light generated? I'm thinking that it
would probably blind anyone within 10 miles, but those leds put out such a
nice soft light that I'm curious if it would work. I've already been
thinking about putting a battery powered led white tail light in because I
went with the no light in tail, but switched to the -7 and now I'm not sure
how to mount the white light on the wingtips without a lot of hassle. Anyone
else have this dilemma, or am I'm missing something?

--> RV-List message posted by: "Elsa & Henry" <elsa-henry@darlor-watch.com>
After Sam Buchanan's warning, and having a -6A, I "bit the bullet" and took
the wheels off to check my calipers, two days ago. With only 42 hrs TT on,
the pistons were hardly protruding from the caliper bores. So I used a
couple of heavy-duty C-clamps to secure the inboard pad plates against the
caliper pistons and had my wife tromp on the brakes as I released the
C-clamps. After seeing the pistons protrude (each side) about 3/16" and
still no sight of the O-rings I concluded that my calipers were OK.
Well done and thanks, Sam.-------Cheers!!---Henry Hore

Hi Bill,
Someone finally did it! There is quite a few military aircraft now running
around with LED nav lights, and whelen has designed some, but not marketed
them. I was actually thinking about putting the same thing together that
you did, but since you did all the work, I'll buy a set.
What is the minimum production run necessary for you to get going?? I might
be pursuaded to help fund an initial production run if I could get one of
the first sets!!
Thanks in advance,

Well, after a few delays, including learning how to use the latest
printed circuit board (PCB) design software, the prototype LED position
lights are complete and working perfectly. I tested the finished units and
they put out more than enough light in all directions to meet FAA specs.
Here is a link to the write-up with some pictures:
<http://www.KillaCycle.com/Lights.htm>
The prototype board is designed to lay flat against the aft wall
of the Vans sheared tip interior space. It's important to note that the
actual physical lay-out of the components is quite fluid. That is, as long
as each of the LEDs is pointing in the direction it needs to, it is
possible to move any of the components wherever you would like or re-shape
the board completely.
The next iteration of current regulator PCBs will be considerably
more compact. I thought I might need de-coupling capacitors, so I put in
pads for them on the prototype PCBs. However, the circuit works fine
without them so I will eliminate the pads (and the space they occupy) on
the next design iteration.

Other folks have suggested this. There are some issues with doing
this. The Whelen lens would probably have to go and be replaced by a clear
lens. I think Whelen makes a clear lens, but I'm not 100% sure. Otherwise,
I would have to mold one up. I would also have to figure out how to cram
all the LEDs in the available space inside the lens, and cram the current
regulator board inside the remainder of the case. I think it is possible,
but I would have to actually have a Whelen unit to fit it all up. Since my
goal was to avoid buying a set of Whelen position lights, I don't own any. :-)

You will notice that I didn't make a rear (white) position light.
The reason is that the rear light requires that you throw 20 candlepower
side-to-side over 170 degrees. Indeed, the candlepower requirement tapers
top to bottom, but it is a heck of a lot of light to throw with LEDs. The
LEDs alone would cost about as much as Whelen rear position light.
through the roof and drags your wallet with it if you attempt to do it with
LEDs. I would suggest HID units as they draw about 1/3 the power as an
incandescent unit for the same candlepower.

Great work, Bill! I've just one question, though. How will they hold up

epoxy might help as long as it doesn't change how the light is emitted...

You wouldn't want to pot it in a block of epoxy because it would
make the lenses on the LEDs work oddly. It could be done, but you would
have to work out the optics and likely use different LEDs. Also, it would
make the unit much more heavy than it is. Right now, it weighs about an
ounce, maybe two.
The only part of the unit that could possibly vibrate are the LEDs
that are bent at an angle. Everything else is solidly mounted to the board.
You could put a little dab of RTV under the bent LEDs and you would have no
worries about vibration.

External amp option. The reason is your intercom has an amplifier already.
If you use the internal power, your stereo will be much louder and more
sensitive in volume than your comm or passenger audio. Plus, you will
always have to turn the volume on the stereo up and down. If you use the
external amp option, you can set the volume one time and forget it, and then
change the volume with your intercom.

Hi Randy,
I'll be flying in on Wednesday too, but early in the day weather

anything about a change in the parking... I'll see if I can find out.
We'll have a tent there as usual but no BBQ. The Blackjacks are supposed to
have a BBQ in the hanger I've used in past years. I haven't decided if I'll
be up there for that. I'm sure we'll find out before Wednesday about
parking, if not you can call me on my cell and I'll let you know what's
going on. It's 206.718.2304. I never have it on, but it will be on
Wednesday...
Flew the Schweizer 2-32 in Cle Elum two weeks ago. Kind of a truck but
fun... Got to work on my formation flying skills that's for sure!
See you up there,
Dave

It turned out to be quite a bit of work tweaking the design,
testing components, and getting it all together.

Short runs are not terribly expensive these days. It will be a
month or two before I have the "production" PCBs, components, instructions,
etc. ready.
Kits will come out first, then I will have time to make a run of
fully-assembled units.

When you see these in person, you have no doubt that they put out
enough light and that you will be seen. It hurts your eyes to look at them.
I tested the units with a light meter. They seem to put out more than they
need to to meet FAA specs.
> Do you have a
>problem with them being too directional at all?
If you notice in the pictures, the LEDs are not all pointing in
the same direction. The middle LEDs are pointing forward, but edge LEDs are
pointing upward, downward, and to the side at very specific angles. Their
light pattern overlaps to give proper illumination in all directions.

The Cheif Aircraft has a special this month (and

Still high priced, but $100 cheaper than normal.

I think you said the magic words, and that is "in a timely fashion".
the original post said he expected the seats by the end of June, well around the
4th or 5th of July he was complaining about bad service. to me that was a very
unreasonable thing to do within 4 or 5 days of expected delivery.
what most people in home built aviation need to understand , and I am sure most
of them do, it that most of these companies are small "mom and pop" places and
as such cannot always control everything that happens. I think that some people
here need to chill!!!!
Sure a good thing that some of you were not building when I built my RV-6,
the only thing you could buy was the tail kit. Nobody had a clue when the rest
of the airplane would be off the design/drafting table.

Further to the misconception that turbos are "on or off" and how they can be controlled.
A turbo charger has two fans and each fan has a fan housing attached to a center
housing. The center housing carries the oil pressure fed shaft bearings and
serves as the mount for the fans and fan housings.
The exhaust (hot side) fan is driven by the exhaust gas pressure. The intake side
(cold side) is driven by a shaft connected to the exhaust fan.
Both sides can be tuned to some extent using a range of differently sized
and configured turbines (blade numbers, diameters and shapes)
Also the fan housings can have several different configurations as to inlet
and outlet sizes as well as internal volumes and contours. These can also be
somewhat manipulated by swapping one for another.
Some degree of mixing and matching can be done to modify the overall scope
of suitability of application.
These among several other tunable variables such as the already mentioned
external controls, waste gate, preset, manual or automatic and the type of
installation, Carburetor before or after the turbo (Non pressurized
carburetor or pressurized), intercooler or not, long or short exhaust
manifold.
A large or small exhaust manifold volume area between the
cylinder/s and the hot side turbine, (this will increase or decrease the
"turbo lag").
The absolutely correctly tuned to suit application is at best somewhat
elusive due to mechanical design constraints and application installation
area available.

Hi, all:
I am not an RV owner yet. However, I am very, very interested in buying
a used one, and am diligently searching. The mission I have in mind is
two fold: Taking my lovely lady and myself all over the US on travelin'
light vacations, and (sound of distant trumpets) commuting between
Atlanta (LZU) and Montgomery (MGM).
One of the aspects of this matter that is somewhat concerning is:
Clearly I will need to fly this commute under IFR conditions.not too
often, but regularly, certainly. Accordingly, I need to ask the
question.
Several non-RV folks have suggested that Van's marvelous airplane would
be a dreadful IFR platform, being all sporty and all. I would counter
that responsive is GOOD, and power is GOOD, and speed is GOOD, and as
such, pooh to them! On the other hand, I suppose one would be best
served by coming to this august assemblage.
The question is, then: RV-4, RV-6.good or bad for IFR? I should think
that a wing-leveling autopilot would help, with a full and fancy
autopilot even being better, but you who have flown the RV's in IFR
conditions..good or bad?
I appreciate your imput!
Jim Harper

Jim,I have no autopilot but I do have a mechanical
wing leveler. I fly IFR regularly. Practice a lot,have
your maps prepared so you don't do a lot of
searching,and just do it, not a big deal.

Bill,
When I asked some time ago about higher compression pistons and
flowed heads (Lycon mods), the Sensenich answer was that the "extra bang"
on each stroke was OK, but the RPM limit was critical, and could not be
violated.
The limits seem to be RPM based (the 2600 rpm limit) rather than
HP based, which makes sense for resonances.....
But ...call Sensenich and ask .... gil in Tucson

--> RV-List message posted by: "Doug Rozendaal" <dougr@petroblend.com>
All,
Stuart Mc Curdy has agreed to hold a Pre-Oshkosh formation clinic at MCW , Mason
City, Iowa, will be the location of the Pre-Oshkosh Formation Clinic. Stu
McCurdy of FFI will conduct the clinic with assistance from other FFI flight leads.
We have a great facility with big wide runways, no tower, limited traffic and our airport is away from the city with lots of wide-open space. Just like Oshkosh, Bring your own tiedowns and ropes. We have a caf=E9 on the field for breakfast and lunch. Our airport is situated between Mason City, 4 miles east, and Clear Lake 2 miles west. http://www.airnav.com/airport/KMCW
We have good ramp space plus acres of nice grass for parking and camping. There
are restrooms in the EAA Chapter office and 1 shower available in my hanger.
The FBO, North Iowa Air Service http://www.ccaero.com/, will give a $.35 discount for fuel. Today the discounted price would be $2.30
The Headquarters Hotel will be the Best Western Holiday Lodge in Clear Lake. They
have a Bennigans bar and restaurant in the hotel. Several other hotels are
listed below. Rooms are tight act now!. Rooms blocks are only reserved until
July 11th Reservations are on your own! Call the hotel and make them today!!!!
There will be a social registration fee of $30 per person which includes a Saturday
night BBQ and Iowa Sweet Corn feed at the Hanger and Sunday evening meal
($20 for one night). We will need RSVP by July 23 to dougr@petroblend.com
with "RV Clinic Reservation" in the subject line. Please do not respond on the
RV-List so my email program can sort it out. Include the names of all attending
and whether they are flying formation or""copilots" This is not a hotel reservation,
food and clinic space only!!!!!
If we discover several spouses are coming we will try to organize some spouse activities,
but at this late date, that will be a shoot from the hip operation..
no promises...
We (or the hotels) will provide transportation to and from all the hotels listed
below. Again, don't look for limo quality service, but we will get you there.
There is Hertz car rental on the field.
There is a lot to do and see in North Iowa, check out the local websites at:
http://www.masoncityia.com/
http://www.clearlakeiowa.com/
Please understand that this is being organized at the last possible minute and
some things will be fluid.
Thank you for coming to MCW! We look forward to a great event.

Maybe so, but communication goes a long way, and it's easy & cheap.
Manage my expectations through good communication and I'll wait a looong
time for your product or service, and be a customer for life.
Let deadlines come and go without the courtesy of a phone call, email,
or update on a web site and I'll take my business elsewhere and won't
hesitate to tell others why.
It's one of my pet peeves too.
