Joe,
I have a 601HDS kit for sale that includes a 2.2L VW with reduction drive (1.6).
I have the instruments/gages/avionics for a full VFR panel. I estimate the work
completed to be about 50% for the airframe. I am willing to sell the kitplane
without the FWF/Engine package.
I know that you are looking for an XL or 701, but this is a great opportunity to
get a zodiac kitplane at substantial savings.
Thanks
Joseph

While you're looking through the archives, look for VW and 601. You'll probably
find my comments about my experience with the VW/redrive. Basically if you want
a STOL, low and slow plane, it should work. Don't expect it to do anything
fast except take off. My 601 would take off before I was ready for it to. The
climb was great for the first 1000 feet or so. Then you had to lower the nose
and let the engine cool.

Try using sheet metal screws. You should be able to get the screws in and

I picked up the floats that I ordered from Sky Shops at Oshkosh. They look great
but I'd like to talk to someone who has already installed a set as I have a
few questions. Hate to reinvent the wheel. If anyone in this group has done so
please contact me by email. Thanks Tom Schulke

Subject: | Jabiru 3300 Econ Tuning Kit |
--> Zenith-List message posted by: Stanley Challgren <challgren@mac.com>
List:
I test flew our 601 HDS yesterday for the first time after
installation of the Economy Tuning Kit on our Jabiru 3300. Previous
to the tuning kit installation fuel burn was about 6.7 gallons per
hour and best miles per gallon was achieved at WOT. Full power gave
about 20 MPG with MPG going doing to about 14 at lowest power
consistent with staying in the sky.
The bottom line yesterday was an average of 4.5 GPH for the 1+11
flight at power settings from WOT down to 2600 rpm. At WOT the fuel
burn was slightly above that with the old needles in the carb. At
2700 rpm I got 120 mph IAS and a fuel burn of 3.9 GPH. The 120 mph
IAS was equal to 118 mph ground speed at 8,500 feet. The 2700 rpm
setting should give me about 30 MPG; a very considerable increase
over the old needles.
Time limits me to the above but I will report more fully on the
Jabiru Engines List when I have fully evaluated and compared the
numbers between the 'old' and 'new' carbs.
Needless to say I am delighted with the Economy Tuning Kit. I should
now be achieving fuel burns less than promised in Jabiru brochures
and far better than ever hoped for.
My thanks to Pete at Jabiru USA.

So how exactly does this tuning kit work..Presumably you are now running
leaner than you were before?...Do you know where you are running
relative to peak EGT?...I.e rich of peak or lean of peak??
I would be nervous if you have somehow leaned the motor to say 50F rich
of peak for fear of detonation. I'm sure Pete at Jab knows what he is
doing but understanding exactly what is going on is worthwile I think.

This is an official Jabiru modification that was made, and is now
standard in all the new manufacture engines. I got my 3300 in June, and
it has this as standard. Apparently all engines since #722 (the first
LSA Certified one) has the new jets etc. They produce a kit to retrofit
older engines with the newer parts.

Stan, you sure peeked my interest ! How difficult was the kit to install and
re set the level of rich to lean ? Did the kit come with instructions ? and
what did it cost ? Did you buy it from Pete and how long did it take to arrive
? Lastly, I have bought a better air filter for my 3300. I observed a test
with my old filter (came with the FWF kit) and this K & N Performance product
sold at Advanced Auto. The test demonstrated about 30 % more restriction in the
kit filter. Have you looked at this type air filter ? Best regards, Bill of

Remember that if the "lean kit" is running the engine rich of peak, that
adding an even less restrictive filter will make it the mixture leaner
and therefore run it closer to the detonation range, unless of course
you are running CV carbs or fuel injection that automatically adjust the
mixture..
I know very little about Jabs but the detonation issues are the same for
every engine.
Would hate to see you guys destroy your engines....:)

Your welcome George,
It would be worth your while doing a search on "John Deakin" He writes a
colum for Avweb...Generally considered to be a Guru of such things.
But in short..If you plot a graph of EGT against fuel flow (fuel
adjusted by adjusting the mixture) you will find that it peaks right in
the middle and drops off either side. If it is on the "Rich" side of
this peak it is called ROP...on the other side it is LOP.
That's the short answer.
Now Max efficiency (Most power made for the least fuel burned is about
25 to 50 Fareignheight on the lean side of this peak...Most power
however is made around 80 to 100F on the RICH side of this peak.
In the Lycoming world this means if you want to go fast (75% cruise in
an RV =200mph) you set the mixture at 80 to 100F ROP. If you want to
save fuel (65% on an RV7 =180mph) you lean the mixture to 30F LOP...Both
of these at full throttle.
Very nice....Just one problem...
The piece of the curve between "Peak" and about 50F ROP is the
detonation zone...I.e running your engine there will destroy it....
So if your "economy kit" is more accuratly setting the mixture say 60F
ROP, leaning it just a little more (maybe with a less restrictive air
filter) could be disasterous. Note I have no idea if this will actually
happen, I'm just waving a flag!
Anyway, note also that in the "detonation zone, Is also where your CHT's
are highest. That's why if you want an aircooled motor to run cool and
last a looong time. Do your cruising about 30F LOP. It's the most
efficient point fuel wise and you engine is running Coool!
I bet your glad you asked...Not...:)
Oh...How do you find peak?....Set your airplane cruising at any selected
altitude...above 7500ft is best, reason being is the above argument
holds true to about 75% power...Which means full throttle (it really
hurts efficiency to run with a partially closed throttle). Start leaning
the mixure slowly and watch your EGT temp....it will start to rise until
it reaches a peak at which point it will fall again....Thats peak.
Note if your fuel distribution is poor then each cylinder will peak at
different fuel flows. Lycomings with carbs are so lousy in this
department you cannot run them LOP because you have to set the "richest"
cylinder 30F LOP and one or more of the others will not be firing at all
and it will sound like a badly loaded washing machine!
Running ROP you have to have the "Leanest" cylinder running say 80 to
100F ROP to keep the others out of the detonation range.

I agree fully with the advice on reading Deakin's articles. An index of
his "Pelican's Perch" articles is at
http://www.avweb.com/news/columns/182146-1.html. There are several
dealing with LOP/ROP/detonation. Besides being an entertaining writer,

Frank, the Jabiru 3300 has a Bing carb and no facility to adjust mixture in
flight. Just got a screw like a lawn mower. Sooo, how would you do all that
other good stuff you said with this kind of set up ? Best regards, Bill

Well you can't...:)
I have the same setup on my Subaru...Sadly. Most pilots (including me)
were never taught how to lean an engine, even those can often choose not
to. So using a altitude compensating carb is a good second best. But we
are missing out on some fabulous efficiency gains.

Hello List,
The Trailing Edges should be square on the ends as shown in the
drawings?
OR
Should they be cut as shown with the dashed lines (on my drawings)?
Thanks

Subject: | 1-Week Sport Pilot School |
--> Zenith-List message posted by: "jim" <jim@pellien.com>
All,
My Zenair Zodiac 601XL will be shipped from the Czech Aircraft Works factory by
the end of this week.
I plan to use it to satisfy the demand for sport pilot training. See the attached
Powerpoint file for the details of the 1-Week Sport Pilot Immersion Course
that we will begin offering at the Bryce Mountain Resort in Virginia starting
in September. I had a tremendous response from people who visited the SportsPlanes.com
booth at Oshkosh. It seems that this is exactly what they have been
looking for. I talked to an insurance underwriter at Oshkosh, and he felt that
this was something that they'd like to see more flight schools do.
Here are the details:
- Semi-Private Instruction: One instructor for 2 students for 7 full days.
- 20 hours flight instruction and solo flight time (if your instructor signs you
off for solo). The FAA minimum flight time requirement for SP (15 hours dual
and 5 hours solo)
- All ground school materials including a King SP training package.
- Ground School "Plus": We have a ton of videotapes and DVD's from Sporty's that
address all manner of aviation topics for the students to explore during the
week....you'll learn far more than the FAA's minimum requirement. You'll learn
how to assess weather and other flight risks to assist you with "GO / NO-GO"
decision making, making you a much safer pilot.
- You'll learn how to access and use all of the online aviation data that is currently
available free of charge.
- You will get a checkride with a flight examiner (if you have progressed far enough
in your training....again the instructor's call). I REPEAT: Some students
will NOT get a checkride nor a SP Certificate. Everybody learns at a different
pace. The decision on a checkride will be made by your instructor.
- Lodging in the 4BR/4BA "Golf and Ski View Chalet" (private bedroom and private bath) is included. The Chalet is directly across the street from the Sky Bryce (VG18) private airport and walking distance to the ski slopes and golf course, as well as the restaurant, swimming pool and tennis courts. For pictures and other information about the chalet please go to: www.pellien.com
- Bring your spouse and kids along if you wish...maximum of 2 kids. They can enjoy all of the resort's amenities while you are learning to fly. Go to: www.bryceresort.com to learn more about the Bryce Mountain Resort.
- "Flying Couples" get a 10% discount off the single person course fee of $4290.
Thus couples can take the course together for a total of $7722.
- If weather conditions are such that you do not get the minimum of 20 flight hours,
you will receive a refund of $70 per hour for every flight hour that you
do not receive. If you wish to fly more than 20 hours in your week and there
is time available, you can fly additional hours for $100 per hour with instructor,
or $70 solo.
- You'll be learning in a high performance light sport aircraft, the Zodiac 601XL
(130+ mph, 1000 FPM Climb, 586 lbs useful load) with a 44 inch wide and comfortable
cockpit with leather seats, radio, transponder, GPS etc. I know that
SP students don't need the radios and navigation equipment.....it is a bonus
for them. When the aircraft is unavailable due to 100 hour inspections or maintenance,
a Cessna 172 will be substituted for some of the non-solo flight hours
on those days.
It is well-known that people best learn foreign languages in an "immersive" environment,
i.e. they go to live in Italy to learn Italian. I similarly believe
that SP students will be better and safer pilots by learning immersively. This
course gives you 168 hours in the nation called "Sport Pilot Aviation". 168
hours of access to a seasoned aviation professional. No more going to the airport
for an hour lesson, then coming back a week or 2 weeks later for your next
lesson, by which time you have forgotten 50% of what you learned on the previous
lesson. You'll learn more, retain more, and progress faster, by going
"immersive".
I'm currently taking $1000 deposits. Only 2 slots are available each week. The
school will run continuously from mid-September on. We are planning to operate
year-round: Friday afternoon to Friday afternoon is the week.
I'm interested in signing up a couple of additional seasoned CFI's with more than
1000 hours of instruction time under their belts to do these 7-day courses.
Anybody interested?
Jim
