Noel,
This is a bit off topic, but have you flown with and without the ventral fin on
your fox ? I am thinking of building one for my Avid if it really helps as much
as I think it will. Can you get the basic dimensions of the fin for me?
Thanks

I have been considering strut fairings for my model 5 and am wondering how to make
sure that they are properly aligned with the slip stream. Do you think that
they are sturdy enough for use on a float plane where folks on the dock often
try to help by grabbing the lift struts?

Hi ! Noel,
you wrote :- It was mentioned to me that the drooped tips
obscure visibility... Has any one else noticed this?
Well I have droop tips but cannot say I've ever been aware of them
obscuring visability, however thinking about it I suppose they must to a
minute degree like on turn onto final, but I think if you suddenly removed
them you wouldn't notice.
Personally I like the look and to my way of thinking they should improve
lift. Also I have clear leading edge tape along the bottom edge put there by
the builder and I figure in a mild ground loop and a light touch on grass
they may protect things a bit especially as the bottom edge is tapered down
from the front. This could let it ride over the grass perhaps. Don't really
know as I haven't tried it yet !
Anyway I like them.

Mine are aligned in the plane of the struts. They will be very close
to aligned, or possibly have a few degree angle of attack.

The PVC ones are definitely strong enough.

Hi Joel,
Alignment: Michel in Norway, and a friend of his from
France, helped me design super slick fairings for my
Fox. They used X-Plane to do the modeling of the
struts for me. What we found was interesting.
The fairings were stalled durning normal climb and
approach speed/AOA. When below the stall AOA, they
could lift up to 40 lbs. This made them speed up the
plane and lift more than their own weight too. A
double plus. But for steap climbs, they didn't help
so much.
We worked hard to come up with a design that didn't
stall during normal climb so that the extra lift and
reduced drag were still there. That part gets a bit
complex. Of course I had to learn not to overshoot
the landings again, because it worked. And I got over
10 mph more speed from them in cruise.
For the normal strut fairings, I would suggest taking
a picture of your wing against the horizon during
cruise flight. Blow the pic up enough so you can
measure the angle of the spreader rod between the
strut tops and horizon, and the angle of your jury
strut spreader to the horizon. With those 2 angles,
you can align the fairings to the horizon as a zero
incidence for your fairings.
But if your spreader bar and horizontal jury bar are
nose down, put your fairings a bit nose down too. 2
degrees max nose down to the horizon. This is
probably because your cruise AOA is a bit nose down
with the KF wing developing too much lift. A little
nose down on the fairings will keep them from stalling
when more nose up, as in climb, and also might take a
little of that extra lift in cruise away making you
fly a tad more level.
Just my opinion.

I have a kitfox lit squared 2 which is the same as a Classic IV. I have
about 2 hours on it and the engine seems to vibrate and excessive amount. I
have no experience with this combination and would like to know if it is
normal.

| Subject: | Lancair Airworthiness Certificate and inspector comments |
- not totally Kitfox related
Brad's Lancair had it's inspection last Friday and recieved its
Airworthiness Certificate. There are several glitches including the custom
instrument panel's inability to power up the audio panel and the transponder
while the avionics cooling fan is powered. Pulling it's breaker powers up
the avionics and the transponder. This is a major major as there is
virtually no access to the rear of the panel and the panel builder is in
Montana.
The real reason for the post is some of the comments the FAA inspector made
during the inspection. I am sure other opinions may vary. By background,
he is a 30 year FAA veteran and spent most of his career in Alaska as an
accident investigator. With that in mind, one comment he made was the
number of souls onboard that he felt died because of cargo or baggage or
what not that impacted their bodies at the time of the accident. In one
case he described the death of a person who was empaled by a fishing rod.
It was his belief that a number of these accidents were survivable had the
gear been properly secured. I'm sorry to mentnion it, but the batteries in
the tail cone have been a real concern of mine over the years.
Another comment was regarding additional crew during the Phase One testing.
It was his opinion that the prohibition of passengers is simply that. That
additional crew is not a problem if there is some reason for the additional
crew being there other than sight seeing or going for a ride. Another
pilot, in his opinion, fine, especially in complex aircaft.
Then came the opinion regarding instruction. It was his opinion that
primary instruction was out, but that a licensed pilot (owner) could be
checked out by another pilot (professional test pilot) and that, in his
opinion, would not be considered instruction. This is what I did and it
feels a bit better now.
That's about it. Oh yes, the airplane came in at slightly over 1800 lbs.
empty. The target was anything under 2000 lbs. The airplane will remain in
primer through Phase one and two, so the final weight will grow somewhat.
My time on the project was just under 1400 hours over two years and two
months.

Ray,
Where are you? You're going to have to find someone with a
similar rig who's close to compare directly.

Some favorites, although I have not seen al those
mentioned.
"The Great Waldo Pepper"
Lynn Matteson noted: I took note of the propping scene
where
Waldo bounces the prop backwards against compression,
to kick the
engine to life...
An old pilot I knew, who learned in the 30's in an
Aeronca C-2, said that was authentic, I think he said
it was a Standard biplane with a Hispano-Suiza engine,
and that is how they were started, rather than pulling
them through.
That movie had great wing-walking scenes, and the
scene of the biplane flying down Main Street in a
prarie town was authentic, they did take down the
wires, though. Had the wrong person as first to do
the outside loop, I think. Good for repeated watching
from time to time.
"Battle of Britain" had many great dogfighting scenes,
using real Hurricanes and Spitfires flying off grass,
and surplus Spanish BF-109's and Heinkles from the
Spanish Air Force, also flying off grass fields. It
also used models for the Stukas crashing in mid-air.
It was authentic to the story. Also good for repeated
watching.
"Hells Angles" is available, but was a disappointment,
not watchable over again for a long time. I think the
new movie, "Flyboys" looks like a remake of many of
its scenes, but with unrealistic computerized
dogfights and pilots able to yell to each other in
flight. Have only seen it once, so don't know how
realistic the story is or about the SE-5a's,
Nieuports, and Fokkers. Sad ending - the main guy
never flies again.
"Jet Pilot" did have beautiful F-80 & F-86 flying
scenes, courtesy of the USAF.
There are sellers of aviation movies. Also check your
local library, ours has some of these because they are
old.
