Et voila! I think the explanation is good.... what
you substract also depends on the bending brake... not
all have the exact same 1/8" radius and that changes
the outcome.

Hi List,
I'm trying to get in touch with Bill Morelli from the list but I haven't
seen him post in a while.
Bill, if you are out there can you e-mail me off list. I have a
question for you on your heater core plumbing that I am pretty sure you
can help me out with.
Thanks

I don't think the hardware store plastic is good enough, if it's PVC I don't
think it's made for high temp. NAPA has various size straight and T heater
hose couplers that are pretty beefy and made for the high temps. For the 1

cut/weld the angle.

--> Zenith-List message posted by: "Ron DeWees" <rdewees@mindspring.com>
Hi Listers,
I agree that folks should build what they have a preference for but one
point that I haven't seen mentioned is that the firewall is a LOT cleaner
without a lot of hardware and bracing for the nosewheel. I inherited a
taildragger as that's what my project was when I got it but I am more
pleased with this configuration as my flight date approaches. My airbox is
flat on the firewall and has a straight 2" shot into the input of the Bing
carby. There will be no rudder centering problems or bearing wear on a
front wheel and there is a considerable weight and drag advantage for a
taildragger. I don't know if this translates into performance improvement
or not, but it sure looks good and I look forward to getting mine into the
air.

Hi Listers,
I have a problem I hadn't expected to run into this soon. I have kept
piddling on my Zenair/Jab in the basement for years and last weekend I
realized that there wasn't a thing more I could do forward till I tried out
the motor. It started immediately and ran great. When I quit smiling I
realized that i am getting toward the end of my construction and am entering
the dreaded PAPERWORK maze. Somehow I thought the plane would fly next
mont, or next month, etc. But it's getting there and I haven't been sending
forms out to agencies, etc.
Is there any one source for most of the forms and information that covers
inspection, licensing and airworthyness of a homebuilt? Since you give the
DAR a pretty good chunk of change do they help guide you thru the process or
just take it up at the inspection process. Suggestions would be
appreciated.
Thanks in advance.

First, you need to contact Zenith an have them send you a bill of sale for homebuilt
aircraft if you built it from the kit. If you built it from scratch, you'll
fill out an Affidavit of Ownership for Amateur Built Aircraft, AC Form 8050-88.
Go to the EAA website (eaa.org) and make your way the hombuilders website
(you are a member, right?) then goto the registration: forms menu. this will
give you a list of all the necessary forms. Most of them can be downloaded from
the FAA website (faa.gov - certificates and licenses). If I recall correctly,
I contacted the local district office and they sent out a pacage with all the
forms in it. Don't forget to check out your state government website for the
state regulations and tax requirements.

Most if not all the information you need is at
http://www.faa.gov/certification/aircraft/av-info/dst/amateur/default.htm ,
including a list of DARs. Find a few DARs and talk to them before choosing
one. Also, call your local MIDO and see what they have to say. Most of the
guys I talked to were friendly and want to hear about my project.

Ron,
I am going through the maze right now for my 701. You can get a package of
forms from your local FSDO office. You will need to register it before the
DAR inspects it. Registering you will need a Bill of Sale and an 8050-1
filled out. Contact Zenith and they will send you the Bill of Sale form.
AOPA has a service for express document submission that will help with
getting the paperwork through the FAA. My local DAR gave me that tip.
I don't have my bill of sale yet, so I haven't contacted AOPA yet, but that
is the method that I will use.

Subject: Zenith-List: Re: licensing the beast
Ron,
I just obtained my Airworthiness Certificate and Airman's Repair Certificate
today from the FAA representative. If possible this is the way to go!
I'd recommend you obtain your N-number registration and bill of sale first,
then contact your nearest Flight Standards District Office representative.
Once you have his phone number, he'll send you the package of forms,
instructions for filling them out and a questionare on you're aircraft
construction, etc and ask where you need to perform flight testing.
I scanned a sectional patch and circled the area needed.
These you will return to him and when it's time you and he will schedule a
meeting
to inspect your bird. There's a 5-page inspect sheet that you recieve in
the package
that will allow you to check off each item as you progress to a finish so
there
are no surprises.
It's a good idea to have your first installation transponder check done and
signed off before he arrives by the locally approved facility. This is not a
big
item, but it requires your static and pitot lines can hold a vacuum thru
20000 ft.
I found the process very well orgainized by the FAA and my representative
was
very thorough and only found 4 items that he recommended be fixed. These
were
not deal breakers, i.e. compass card, one bolt shorter than required,
electrical boots
on contactors and one loose wire that needed a tie-tie.
Once these things are fixed, I'm free to fly and work out the test flight
objectives
and hours.
If you have a DAR, I'd expect to see him do all this for you very
reasonably, because
it didn't take a lot of time

Thanks to everybody who responded. We have now solved the problem. The new
tyres were not "round", ie, if you put a rule against the outer edge and
rotated the wheel, the circumference moved in and out by at least 1/4 inch.
Also, they were both grossly out of balance. We bought 2 new 480/400 x 8
tyres and got the wheels balanced. The result is no vibration at all and a
smooth ground run for as long as you can hold it down before take off.

| Subject: | N601RT, the first year flying (long) |
--> Zenith-List message posted by: royt.or@netzero.com
Today (5/12/04) is the anniversary of the first flight of my CH601HDS, N601RT.
During the past year Ive flown 196.5 hours (almost made 200) and have 205.3 hours
on the hobbs. 284 landings. Based near Portland Oregon, 40 hours were my round
trip to Oshkosh. Most of my other flights have been local. Ive really enjoyed
the plane. Ive flown 19 passengers, including one Young Eagle.
THANKS to everyone who contributes on the Zenith list for helping me complete my
plane.
I cruise at 100kts, 5200 RPM, burning about 5 gallons per hour. Block to block,
I average less than 5 GPH. I use premium auto fuel when it is available. Initial
climb is typically 800-1000 fpm at 70kts. Ive flown as high as 14,200ft, 15820ft
density altitude, estimated weight at this altitude was 1035lbs. Initial
max speed was ~100kts, recent top speed test result in 104-105kts (three leg
tests, GPS measured speed, autopilot tracking heading). I attribute slight increase
in speed to improved canopy sealing, addition of nose gear fairing (~2
kts), and engine break in.
Maintenance/repairs have included: replaced Turn Coordinator (warranty), repaired
electric Directional Gyro (warranty) broken oil cooler mount (twice), lost
spring in exhaust system, replacing left rear exhaust pipe which broke, replaced
TruTrak autopilot servo with higher torque servo, replaced tail light bulb
several times, replaced tail light lens after dropping original which shattered,
added Ls at muffler heater shroud to help retain shape, replaced oil pressure
sender, added slipper clutch to Rotax gearbox, update starter to new version.
New carb flange and coolant system pressure cap arrived yesterday and will
be installed within a week.
N601RT highlights:
Nose gear with nose wheel fairing
Rotax 912ULS powered, 3 blade ground adjustable Warp drive prop.
Rotax radiator custom mounted in cowling with custom baffling.
Unpainted
Well equipped (over equipped?), IFR capable all electric panel, built by Pacific
Coast Avionics.
Dual alternator, no vacuum system
Brakes re-engineered, hold easily at 4000RPM. Optional passenger side brakes installed.
Oregon Aero built and covered leather seats. Oregon Aero also made arm rest and
stick boot.
Original style side opening clear canopy
~29 gallons of fuel capacity 2 leading edge tanks + one wing locker tank
Empty weight 660 lbs. Registered gross weight 1300 lbs.
I dream about making a GGP like forward tilting canopy. Also noodle with raising
the skin behind the canopy to reduce drag. Plan to install main gear wheel pants
at some time. I plan to make fiber glass wing join covers and plan to add
fiber glass to bottom of cowling to make it more like the XL cowl. I also expect
to get an air adjustable propeller someday. After these changes, I might
get some paint on the plane.
Those of you who are building, keep after it. My building experience was lots of
fun. The flying has been GREAT.
Regards,
Roy

to catch pilot Gus perform a beautiful first flight of the ZenVair 601XL Corvair
Cartel plane..many of you saw the very nice plane on display at the Zenith
site at S&F..It was signed off Sat, and flew about 19:30 this afternoon..the
champagne cork popped shortly thereafter...another one has left the nest!! Details
will be on the Corvair site shortly, I;m sure..Congrats

I just replaced my front tube due to a slow leak in the valve of the
previous one. Interestingly, the replacement caused the wheel to go way
out of balance. Very significant vibrations as the wheel spins down
after takeoff. It almost felt like it was the prop but was indeed the
wheel. I never did balance the original installation, but I clearly need
to do so now.

Frank,
Just a thought on this. It's unlikely that the tube alone would cause
that much imbalance. More likely that the wheel and tyre are both out of
balance but that the tyre just happened to be fitted in the right place
on the rim so the imbalances cancelled each other out sufficiently that
you didn't notice it. The tyre has probably been refitted in a different
place on the rim with the fitting of the new tube and, voila, instant
vibes!

I just replaced my front tube ... Interestingly, the replacement caused
the wheel to go way out of balance. Very significant vibrations as the
wheel spins down after takeoff. It almost felt like it was the prop but
was indeed the wheel. I never did balance the original installation, but
I clearly need to do so now.

Frank,
just a quick note to make sure you are aware of the "light
spot" on tyres. This is marked on aviation tyres with a (normally, but
may differ with manufacturer) red triangle on one side, this is where
you should have the valve positioned during reassembly to ensure as
close to possible static balance, meaning a minimum of weight (or
hopfully none) will have to be added during dynamic balancing.
