Paul,

Please elaborate. Your reason for choice would interest us all.

but I have to question your statement below in defense of
taildraggers - "more prop clearance". I know it is possible to take off with
the tail still on the ground, and the favored landing is a "3-pointer", but
I think most taildraggers will raise the tail asap on takeoff, for me that's
usually less than 2 seconds into the roll. So for most of my takeoff roll,
most of the time, it is rolling the same as a tricycle gear in terms of prop
clearance.

How about landing in the rough? You certainly can get more prop clearance. The same
goes for taxiing. I think that most of the rolling on the ground is other than the
take-off roll. When you are trying to get to the place you want to do your take-off,
you can taxi with more prop clearance, to keep the prop out of the grass and gravel.
When you pickup gravel nicks in your prop it is right at the beginning of the takeoff
roll. Once you're moving and the tail starts to come up, you're not picking up as much
gravel. The tail dragger has an advantage at the beginning of the takeoff roll that
can't be achieved with a tricycle gear airplane. You can also delay raising the tail
until the main gear starts to lift off, thereby maintaining propeller to ground
clearance. I do agree that extends the takeoff roll.

I can hear your response as "Ah, but you have the choice" and also recall
soft-field training in a tricycle with the yoke in my lap to get the
nosewheel out of the grass/mud asap. So maybe a better point would be that
taildraggers always offer soft-field short-field performance? Also -
wouldn't rolling with the tail down in a taildragger be somewhat
counterproductive due to the large increase in drag due to the high
angle-of-attack and not travelling inline with the thrust vector?

Agreed. However, as you say, you have the option and you certainly can keep the prop
up out of the weeds and from picking up gravel at the beginning of the roll.

I think there are a lot more options for fun with the small tail dragger. I've decided
that after owning a Cherokee 160 and a Turbo Arrow for many years. That type of flying
is more for commuting than for exploring. I do that in a Boeing, nowadays and have
changed my purpose for an airplane.

I gotta get my two cents worth in here...when I flew my Kitfox
taildragger to New York to visit the Old Rhinebeck Aerodrome, and
asked if I could land there, they asked me if it was a taildragger
and I told them yes it was, and they said come on in. They had an
incident with a nosegear plane and their insurance company said no
more nose gears, thank you. Besides, a nose gear plane landing at a
field where conventional gear WWI planes are flying? I don't think
so, Al....: )

I couldn't agree more with this statement.

It reminds me of the time four Kitfoxes were on the way to the annual
informal Dichondra Field fly-in. I was preparing to depart for our assemble
point when an RV-4 pilot asked me if I was going to the fly-in and asked to
tag along as he didn't know where it was - a commercial dichondra farm
somewhere in California's central valley. Sure why not. After hooking up
with the others at Rancho Murietta it was off. Once airborn, however, the
Kitfoxes decided to follow the river at tree top level and the poor RV guy
orbited overhead with nothing else to do but watch us having our type of
fun.

This obviously has nothing to do with tailwheel vs. nose wheel, but it does
describe pretty well that there are purposes for the various types of
aircraft. I sometimes wonder why my Lancair friend enjoys his flying so
much as all he can see at altitude is his panel and a gray haze below him as
he flys at his 250 kts. Maybe that is why he wanted a fast airplane,
because in his experience flying is pretty boring, but owning a screamer is
big-time ego food.

I guess there is no bad reason for choosing one configuration over another
whether it be prop clearance, the airplanes intended use, high insurance
premiums or fear of cross winds. It just has to be a personal choice we
make and then live with.

You're asking an old(er) pilot to elaborate!? Here come the stories... (as I
type this I see Lynn has already added one of his own<g>)

How do I prefer thee taildragger? Let me count the ways...

1. I keep my KF2 on a trailer in my barn and fly from a grass field (8N7)
about 5 miles away. I am the only plane "based" there, although others
visit, and the only open runway is a bit rough to say the least. Taxiing can
be bone-jarring but since the weight is off my wheels within seconds and I
am off the ground within 300 ft it's not bad at all. I couldn't imagine
bouncing along for 1000ft in a C-172, although I have done just that.

2. As my recent BFR I did a couple of hours type-training in a 172, which
included several (6) short-field grass strip visits where I got to practice
full throttle with brakes, yoke in your gut (sucked in), 40* flaps,
tight-rope balancing on the mains to "keep the weight off the nosewheel",
and then once off flying the remaining runway "in ground effect". And I'm
sorry, I've done ground effect in Cherokees and Warriors, and a Skyhawk does
not do ground effect with those high wings. All the while I was thinking
"can't wait to visit here in my Kitfox".

3. I took a ladyfriend from 8N7 to the mile-long paved runway where I fly
the 172 for a $100 ($5 in a KF, plus the price of the burger) hamburger and
was even impressed myself at how smooth the landing was and how fast we got
off the pavement. The only disadvantage was the long taxi times given how
little runway I used. The attention from other pilots during the taxi made
it worthwhile however. Pretty lady, pretty airplane, life is good sometimes.

4. I have made a one-way(slight slope) runway behind my house that is only
400ft of babies-butt smooth grass but has 100ft overrun (neighbor) on one
end and 50ft on the other. I still don't feel confident enough yet to try it
but 8N7 has white painted tires every 200ft so I can gauge my takeoffs and
landings accurately for practice. Kids - don't try this at home, or in a
tricycle gear.

5. The "oleo strut" on rentals/trainers seems to be the thing that is always
failing or about to fail, with 3 Skyhawks to choose from it pays to know
which has had it's front wheel repaired/replaced most recently. Not a
problem I have to worry about with my KF2. BTW I see a lot of complaints
about failed tail leafsprings on this list, in the UK it was mandatory to
mount a Maule tailwheel assembly as the Denney one was considered
unsuitable. I have never had a problem.

I could go on, but that's enough for now. And please note - these are my
personal preferences according to my personal circumstances, not
who's-is-bigger-or-better.

I had the same experience at Old Rhinebeck just a few months ago, although I
hadn't flown in and was asking if I could for next year. Taildraggers only,
like the old sign on the treehouse "no girls allowed". And there's no
beating the feeling of the crowds thinking you're part of the show - I'll
bet you slipped it in right in front of the stands didn't you Lynn?

Nah, I got there at about 8 am...no crowd (damn!)...and just flew in
from the north end, following the slight bend in the runway, missed
the big flat rock that sticks up about, what, 3 inches?, and taxied
to the far end....no problem. I had to get out of there before 10 am
or stay until after 5 pm, so I headed back to Kingston, across the
river, and drove back later for the show.
