Color of aircraft (was S&F)

MitchDCGS@...
 

Can someone tell me exactly what colors might be acceptable??  What about
YELLOW like the color of the 2000-2001 VW Bugs?  Is this a bad color too???
Thanks,
Don

_________________________________________

Thanks for the response Dave,
I understand the concept of white having the lowest heat build up, but the
question is how much heat build up is acceptable and which colors will allow
the heat to remain under this "critical level"???  Last year I ran across
something on the internet that actually showed the difference in heat
absorption of various colors.  I remember thinking to myself that this will
be useful information someday, but now I can't find it again.  Anyone out
there have anything to add??  I've asked this same question several times on
this forum but never got a reply.  I know white is best, but what other
colors might be acceptable.

Thanks,
Don Mitchell

To the group,
As a person who has found out the hard way about the disadvantages of dark
paint on an aircraft I bought, I can so visible proof to anyone who disputes
the validity of this concern.

I believe that just maybe, if we did a well intended and respectful petition
with names and e-mail addresses of individuals concerned with Pedro's
safety and included documentation like mine, he just might understand why we
are all so concerned. The issue here is multifaceted, I for one don't want
to see anyone have problems and I respect the individual agency of all to
make their own decisions. However, proof IS proof. And further, a
respectful petition could show our concern as a group for his safety and our
image.

Let an orbiting Ez driver feel more at home in the International Space
Station by sending him a picture of your Ez

Frank Caldeiro, astronaut and Long-EZ builder-pilot, has made a very
special suggestion to us. I think we should make it a priority and get
those pictures in before the deadline. Send the picture to Frank, not
to me! It seems a project photo would be interesting too, for those of
you not flying yet.

Frank wrote:

If you guys have any pictures of your Ezs (no larger than 6x4) that you
want delivered to Jim Voss at the Space Station please send them to me
before May 5. I know it is very short notice but we hope to send them in
the next shuttle flight.

Put your name and home base on the back so Jim knows who you are, also a
greeting would be great.

I figured Jim will appreciate them, and at the same time you can boast
about having your plane moving at 17500 miles per hour in low earth orbit
while travelling millions and millions of miles. Top that!

No guarantees on returning them, best case I'll retrieve them personally
(some day), worst case they come back to Earth in a Russian Progress
a-la-MIR style.

Please keep in mind that we are volume limited so if the response is too
great please don't be disappointed if your picture does not get to Jim
this time. First come first served.

Please let other Ez builders/drivers know about this. The more the
merrier.

Re: LEANING / DETONATION (was Glide Ratio...)

brian amendala <solongez@...>
 

Art, I think you are right. At the end you state that maybe some guys get away with it, but you know what? They probably are not getting away with it. TBO is DIRECTLY affected by mixture, it's the most critical one, so they probably aren't getting the 2000 TBO or their engines art really hurting at 2000, when the could be a lot safer by leaning on the RICH side of peak.

From: Art Bianconi <British-Biplane@...>
Subject: Re: [c-a] Re: LEANING / DETONATION (was Glide Ratio...)

Because we have fixed pitch props, lugging the engine is not likely.
However, in a recent post someone wrote that it is impossible to hurt ANY
properly running reciprocating engine by leaning. I disagree.

You run a complex A/C with CS prop at low rpm and high manifold pressure
and then thin that mixture while that engine is under that load and the
debris you drop from altitude .....

Cracked jugs from thermal shock is a problem most every pilot risks on
air cooled engines during protracted let downs without power; some
(turbo's) more than others.

Bad Mix

Dave Black <dvblack@...>
 

Here's a question for the group:

With an infinite number of monkeys and an infinite length of time, I suppose
an epoxy mixing error was bound to happen. Reading my scale wrong, I mixed a
batch of epoxy with 1/3 the proper amount of hardener. I used that epoxy to
make Micro for filling the surface of my elevator. Two days later, the filled
area still yields to the fingernail.

So my question is: What's the best way to remove this Micro from my elevator?


Thanks,
Dave Black

Air Foil Change

Paul Werner <ezepilot@...>
 

Hello Group

There is a little info that I can add about my plane. The winglets
that I said were removed were the the lower ones of course. Some
responses have suggested that the wing might get less lift in proportion
to the canard and offset that balance of the forward and aft lifting
surfaces. I can say that my canard is the shortened version and that I
am a 200 pounder sitting in the front seat. It does look like it was
filled in afterward. The strakes or engine cowlings, wing roots and
wing tips have the correct concave. The wings just seem to be flattened
in the middle between the outside of the ailerons up to a point about 10
inches in from the ends.

Paul


Re: Air foil change on VEZ

David Wells
 

Hi Paul,

Don't know how much I agree with this statement. My Vari is far from
flying and I am talking in an academic sense on this topic. Yes, there
will be less lift from the wing since it is missing some camber, but
there is another issue that must be considered. Because there will be
less lift over the aft portion of the airfoil section, there will be
less nose down pitching moment. This will affect trim drag since the
elevator will have to be at a more TE up position for equilibrium which
will probably result in less drag, but might not depending one how far
up it must be). BUT...there is ALWAYS a but...now you have less nose
down pitch authority. If you get behind the power curve and into a
high sink rate condition at slow speed, you may not be able to get the
nose over far enough to get out. There may be other issues as well,
but that is the most obvious to me.

Dave

...VEZE with a straight edge laid up under the wing from the thickest
part in the middle to the trailing edge shows about an eight of an
inch to 3/16"concave. Being a little familiar with airplanes and
gliders I feel that this flattening of the air foil by the builder
was done on purpose to lose a little lift and gain some speed. Not
sure if the foam was cut out like that or if they filled it
afterwards...

Re: Second / Third - owners

Bill Allen <bill@...>
 

Us aircraft owner/flyers/builders can be sensitive to criticism sometimes.
Occasionally the blunt approach will get the message through for all the
reasons previously posted. If I saw Pedro, I'd try to make the main point to
him clearly and concisely with something like "You're going to kill yourself
in that". It will probably get his attention. (forget all of the above if
he's bigger, faster and uglier than me....)

Peter,

Happen to doing work on a Varieze right now, (axle change --
don't ask/don't tell) and I just took the measurements and if my
mind serves me correctly the distance from outside to outside of
the gear leg is 51.9 inches. I have a chance to go "King" Salmon
fishing this afternoon so I'm out-ta here but wil check when I
return in a few hours and get verified measurements. This
Varieze has been in service since 1986 so will be interesting if
others respond. I would caution to only use measurements to the
strut and not the axles since many different axles and mountind
locations could give a false reading.

Thinking along the same lines as you, I asked Pedro

replied yes. I used the information in the plans
as a basis for needing to use lighter colored paint

Sounds like you tried. Guess nature's laws of "natural selection" will now come

Hi Team:
It has been pointed out that the URL for the John Deakin article on

It doesn't take much. Computers always do exactly what you tell them to do.

Whether he respects your 'intrusion' or not is of little importance. You'll

HUDS

Rick Girard <fly.ez@...>
 

Just finished a three hundred mile trip into the setting sun in my
bosses 2000 Pontiac with a HUD. Works great, really spoiled me, even
told me what frequency the radio settled on after a seek. Couldn't see
any special coating or anything on the windshield. Did, however, notice
that the unit was nicely framed and recessed into the dash. The
combination added a reflection that framed the image, lightly, and
helped draw you eye to the display. Go out and take one, or something
similar, for a test drive. You can ward off the salesman afterward by
telling him of your plane that's built much like a surf board. :~)

Stainless Brake Lines

Sorry for the repost but this bounced to his address, thought I'd try and
reach him here.

Larry King,

What follows is the original post I made with the vendors and part numbers.
Let me know if you need anything else.

Stainless Brake Lines

The number one answer to your question is Swagelock fittings. You will
probably need 1/8 pipe to 1/8" straights and 90 degree elbows. We are in CA
and our dealer is Angeles Valve and Fitting, their phone number is (213)
849-6257. Call and ask for Ray. He is very knowledgeable about the product
line and you can buy what you need with a credit card. We are assuming you
are running nylaseal from your master cylinder to your stainless. You need a
1/8 pipe female to 1/8" tube fitting, you'll find this on page 20 of the
Swagelock catalog. The 90 degree elbow 1/8 pipe to 1/8" tube can be found on
page 14. The 1/8 pipe to 1/8" tube straight is on page 7.

The stainless is 0.125" x 0.020" x 304L seamless purchased from Alvin Metals
Company in Culver City, CA (323) 870-1780.

What you are going to do is fairly simple, I'll describe two likely scenarios
that are somewhat similar.

1) Master cylinder in the front, 90 degree nylaflow fitting (brass), nylaseal
tube running aft from this fitting to just aft of the rear seat bulkhead
where a straight nylaflow fitting will thread into the female 1/8 pipe to
1/8" tube. This tube will run down the back of your gearleg through the
original nylaflow tube and more than likely plug into a 90 degree 1/8 pipe to
1/8" tube Swagelock fitting in the caliper. Make certain there is sufficient
room for the stainless to flex without work hardening.

2) Master cylinder aft of the firewall, nylaflow fitting (brass) to nylaseal
tube, through the firewall into the landing gear bay just aft of the seat
bulkhead. Now follow all of the instructions listed above. One other note
about the caliper end, we have used Matco brakes so we have two calipers to
deal with. The interconnect between the two had been a source of concern
regarding a crossover tube resistant to work hardening. We found two 90
degree Swagelock fittings facing each other from caliper to caliper created
very favorable geometry allowing the tubing to exit one fitting and loop into
a two or three coils before entering the other 90 degree fitting. Now the
calipers can move independently distributing the flex in such a manner as to
completely eliminate work hardening.

A bit of advice here on brake fluids: we highly recommend ATF Mercon or
Dexron III. It is cheap and far exceeds the mil spec stuff recommended for
use in most aviation applications.

For those of you who read this and may not have understood the significance
of nylaflow versus nylaseal, nylaflow tubing is affected by moisture content
in the air [it needs moisture] and ultraviolet light will damage it. Nylaseal
is the only tubing of its type recommended for brake lines.
