| Subject: | Re: how to kill yourself with the flaperon handle |
Thank you for sharing your story, Jeff. My Kitfox 3, that I didn't build myself,
has a stopper at 10 degrees flaps. I have read many scary stories of too much
flaps on the flaperons and this is why I never use them, if it isn't as an "elevator
trim" with a very few degrees, to counter the nose-up tendency at level
flight in smooth air.
To go through a hole in the cloud, I would prefer the side-slip method, which I
use intensively on final approach. I just love it.
Some years ago, I participated to a navigation contest in the Norwegian mountains
and, in order to land at the correct time, I had to descend from the top of
the mountains, to 1,000 ft AGL in the valley, rather quickly. I came down along
the mountain side by left and right side-slips what were just like ... skiing
down a hill! It was so much fun and it felt so ... natural to slip one side,
then the other!
If I had to go through a hole in the cloud cover (which I am not really allowed
to because the European ultralight rule forbids us to fly "on top") I would do
it ... the skiing way! ;-)
Cheers,
Michel Verheughe

Spoilers would certainly be an interesting addition to a Kitfox. My experience
with float is that the approach is flown too fast, and stall times 1.3 makes landings
pretty float-free in my Model I. It's almost an unnaturally-low speed,
so my Kitfox friends and I don't always use Vso x 1.3. And we get float as a
result, and just accept it.
However, floatless landings are easily possible by flying the approach at Vso x
1.3. But since stall speed changes with weight (quite a lot in a Kitfox), the
approach speed also changes with weight. So it's good to know what is Vso for
a variety of weights and then to know what your is your present landing weight,
and then look up your target approach speed.
One method is to fly at whatever speed you wish on approach (say Vso x 1.7) and
just begin to increase angle of attack at a higher altitude, the idea being to
reach the ground just as Vso is reached. When approaching at Vso x 1.7, I'll
start increasing pitch at perhaps 100 feet and just keep increasing pitch until
touchdown. This means aiming short of the landing point, which is fine as long
as there are no obstructions. Also, slips are a great way to control descent
rate and approach angle.
All this can be done with the three flight controls that are already there. Just
takes practice.

Just curious, what was your IAS at the time you pulled the flaps?

Higher than normal, probably 80+ mph. Initially pitched down like
normal when pulling flaperons, this I compensated with elevator and
trim but then the elevator just went away, and the nose pitched down
hard. I thought I stalled the wing. BUT now after thinking about it over
night, I'm inclined to think I stalled the tail.
My plane has an IO-240B and a variable incidence tail. So I had a
lot of trim rolled in, and I'm nose heavy to begin with. I'm pretty sure
the tail either got blanked out by airflow, or simply stopped flying.
Which ever it was the stick stopped working until I pushed, and got
out the flaperons.
By the time I got the plane under control I'd dropped at least a thousand
feet or so, had I not been secured in by my belt it would have been all
over. I actually had a lot of shoulder pain immediately after from trying
to grab the flaperon handle. But I was so happy to have control of the
plane again I remember thinking I didn't care if the arm fell off. Then I
just sat there in a mass of debris (maps, etc) thinking I need to do a
better job stowing my stuff in the future.

| Subject: | Kitfox Super Sport panel |
I am looking for a basic outline of an Kitfox Super Sport panel as a starting point
to do my panel design with TurboCad or AutoCad. Does anyone have a file they
are prepared to share or know where I can download one?

Scary stuff. I have changed the position of my Johnson Bar flaperon handle so
I can get to it in a hurry and not have to look down. This helps a lot for those
times when you need the flaperons in a hurry or when looking down in the cabin
is not a good idea.
