| Subject: | Yaw Left in the Flare |
I am interested in the left turning tendency in the flare. I think Doug
might be on to something when he talks about the gear and a weight
asymmetry. I am wondering if the left turning tendency happens when there
is just a pilot on board (weight on the left wheel). As an experiment,
someone might try a few landings flying from the right side. Does it yaw
right then? But be careful because you won't have any brakes.
Maybe I will try to get my ex-wife to stand in the middle of the runway
when I land and do some filming.

I had one of those "left turn tendencies" as well in a strong cross
wind. I found my problem is with the front wheel tied to the rudder
inputs... you have to remember to neutralize that at touchdown otherwise
you just follow where your front wheel is pointin'.

Interesting thought, Paul.
This is a concern that I have had about my 601XL, born of the simulated
"flying" that I've done with X-Plane. If I set up the simulation in a C-172
with a strong (say 20 or 25 kt crosswind from the right), the tail wants to
weather-vane, turning the plane into the wind. I cannot taxi in a straight
line without a lot of left rudder. But, if my nose wheel is linked to the
rudder, then I'll turn the nose wheel to the left, and it will want to
steer me to the left. The question is whether, in the 601XL (or 701), the
rudder requirement and the nose wheel steering can be balanced to allow one
to steer in a straight line. I'm intrigued by the steering mod used by Larry:

Has anyone else tried this mod? How did it work? Any effect on the landing
turn tendencies?

Hi guys,
I doubt the springs would help to align the wheel if, while landing, you
were still not centered. In a smooth landing, even the main gear slides
a bit before gripping the concrete. The nose gear lowers much later and
could still be misaligned enough for the springs to aggravate the
misalignment and swing the aircraft further out, throwing you off the
runway. I prefer the solid connection that greases the nose gear and
adjusts it only once due to positive steering. Try it in your little
kids red wagon first and see what happens.

He seems to be a good guy he's on the RV forums I'm getting the whole set up from
him for my 801.

| Subject: | Re: 801 Landing Light |
On my 801 I fabricated an aluminum plate the sandwiches between the fron
t gear leg and the fork. This is the place I attach my tow bar to and th
e top surface is where I mounted my landing light. A 3" round spot beam,
I took out the 55 watt halogen bulb and replaced it with a 130 watt rac
ing one. Works good for me.. I did see an 801 at OSH, I think it was La
rry Landucci',. He mounted his on the front of the landing gear just inb
oard of where it attaches to the brackets. he used two lights, the littl
e oval ones. Bottom of the fuselage will shade the light from the pilots
eyes and cast a nice pattern under and out in front of the plane. If I
had to do mine over again I probably do it his way...

Thanks Ben. Do you have any up close and personal shots of your mount. Super
sharp plane by the way.

Since 1995 I fly a plan built 701 with a R912 and kit built Z 950 amphib
floats. I have 490 hrs on wheel, skis, and floats. For my needs the 701 has
been a great aircraft, given me much pleasure, both while building and
flying. I made a number of modifications while building and over the years
added others, some cosmetic, others I consider essential for my particular
use and safety. A number of these were to the fuel system which has been the
subject of discussion on this list recently.
Originally I had the large collector/nose tank and two optional 22 litre
wing tanks feeding parallel lines in the engine compartment.The main line
fed through the engine pump, the emergency through an electric boost pump.
They had filters and met at a cross at the top rear of the engine to feed
the carbs. This was a popular and common configuration in the mid 90s.
Except for minor feed issues from the wing tanks this system worked well.
However, even with the battery at the extreme rear, the CofG was too far
forward making power-off landings challenging and with the addition of
floats dangerous. In addition I was not trilled with sharing the cockpit
with 30+ litres of fuel.Hence one of my first major mod was getting rid of
the nose tank and moving the battery forward to the firewall. To feed all
the wing fuel safely I added a collector to the back of the baggage
compartment.
The shape of the collector is important. First the tank only holds 8.5
litres and is high and narrow so when it starts to empty the two fuel level
warning switches at the top activate promptly to announce 30 minutes fuel
left. To enhance this feature the warning switches are located in a ridge
across the top. The bottom of the tank is conically shaped to form a
sump/gascolator connected to a drain on the bottom of the fuselage. The fuel
feed with a finger screen attached is 2"off the bottom to minimize picking
up debris/water. It uncover with about 1/2 litre remaining in the collector.
The front of the tank has the wing feed connection and a sight gage with a
black cork float to monitor the depletion of the last 8 litres available.
Finally the top ridge has one of the warning switches (the other is on the
right top side) and the connection for the vent which connects to the top of
the right wing tank. (I've attached a couple of photos of the tank and its
location).
Management is simple. Fuelling is done over the wing; I usually only use the
right tank. Additional ground checks are to start with the wing tanks OFF
and check the low fuel warning light operation. It comes ON in about 3-4
minutes after start. I then turn one wing tank ON and confirm it is feeding
(low fuel warning goes out) and visually check the collector is full before
T.O. In smooth flight the low level warning activates pretty sharply when a
wing tank empties. In rough air it will start to flash 20 or so minutes
before it comes ON steady. In a steep descent while feeding a low wing tank
it will come ON within 30 seconds indicating an interrupted feed.
This system has worked well for me and friends that have copied it. I am
confident flying down to a couple of litres (1/2Gal) if need be without
danger of interrupting the feed.
I'll tell you about a more recent mod to my fuel system due to the
increasing amount of Ethanol in our mogas here in the "land of the
freeze".I'll save that for my next post. Also att pic of my a/c 2006.
Smooth landings.
