This is the first time I have flown one of these
since I was fourteen or fifteen. I forgot how bad it
was.
Horrible handling airplane. Terribly un coordinated.
Don't learn in it unless you can afford to spend twice as much time
and money. The flying skills you learn are then useless for flying any
other
type of modern aircraft.
However it is fun and challenging :)

Flying something like a Cub or Champ will make the automatic parts of your
brain ready to work without you thinking about it. You call it bad, but
it's actually perfect for flight training. If you can make the Cub do your
bidding, the only problem you'll have with the RV is getting used to its
small and light control inputs. Some people might over-control in the
first
few moments of transition. Hopefully you will get you a bit of stick time
in another RV before having to do it solo.

The reason it is bad is nobody designs an airplane today with out due
diligence to coordination and aero balance of the controls. There is no
upside to uncoordinated and unbalanced controls. It is like an old
unstable
car. Yes you can learn to drive it but why do that if it can be made
stable. Therefor I disagree with the idea it is perfect for flight
training.
Get lessons in a C172. After you have your license get checked
out in a Cub if you feel the need to find out what it was like to fly in
the
1930's. Build a replica of the Wright Flyer if you really want to learn to
fly a bad airplane. Yes it was the first barely controllable airplane but
technology improves.
The other Cub drawback is the early versions did not
have flaps so the flare is very nose high which totally obscures the
runway
ahead. In fact Piper lost a huge law suite about 30 years ago because of
this factor. As I recall it bankrupted them. This had a very negative
effect on the light plane industry. Cessna stopped building and selling
piston powered aircraft. Congress had to enact a law prohibiting liability
suites for products 17 years or older.

Hi Paul, I think the big suit at that time was against Cessna for
failing seat latches that would leave the pilot in the back seat hanging
on to the yoke after lift off. I did not see any comments on my "Bass
Akwards" article. With such a knowledgeable group, I was expecting
something.

That was another one.
I had to modify my 182 for that one.

"The trike arrangement with the single front wheel leads to terminal
oversteer, a spinout, when pushed to the limit."
Not necessarily true. Under steer over steer has nothing to do with where
the wheels are and how many. I don't think he knows what he is talking
about using these terms in this context. Slip angles vary with load
and tire construction. The coefficient of friction of a tire also varies
with load. Higher load lower coefficient of friction. Therefor side
force generated can vary widely. The major effect is the CG being behind
the center of side force. If what he says is true fully locking tails
wheels would
be more popular. Has anybody on here flown a fully locking tail wheel?
Paul Lamar
 Less than 40mph stall speed and you need flaps ? Virg
Have you ever hit a pickup truck on the runway at 40 MPH? :)
The flaps keep the nose down at slow speeds so one can see.
Paul Lamar
Awful lot of technology going on about landing a plane. Â Just fly it
down and land it. Â Ask RV4 pilots who fly a lot if you should make
wheel landing or 3 pt and do it. Â I can't even imagine not doing
wheel landing in cross wind, but haven't flown low wing tail
dragger. Â Also, you can see ahead with wheel landing just like if
flying trike gear. Â You touch down with nose as low or lower (since
no nose gear to hit first) than in trike gear. Â You keep pushing on
stick to keep nose down until tail finally falls on its own because
to slow to fly. Still have rudder control for few seconds. Â Then
slows down and you lose that. Now you better have brakes that won't
get hot and fail because the brakes are what you steer with. Â Forget
the tail wheel except for taxi (unless RVs are way better than other
taildraggers). Â If strong xwind and brakes fail you're going off the
runway. Â Just hope you're slow enough by then that you don't hit a
wing tip when you have to ground loop it to keep from hitting something.
But, you have good brakes. Â So, you will always be able to
steer. Â These RV tail draggers can't be hard to land or there
wouldn't be so many. Â You will be fine. Â Forget the cub and get dual
time with RV taildragger pilot or low wing warbird taildragger
pilot. Â They can show you best way to land it. Â But, I can't stress
enough to learn wheel landings. Â Then you can land anywhere any time
you need to.

True wheel landings are the answer but that negates the whole idea
of a tail dragger in the first place. You cannot make a full stall
low speed wheel landing. That is the wing angle of attack is not
high enough. That also implies a longer runway is needed. Tail
wheels are supposed to be
better in rough, soft field, full stall landings off airport at the
lowest possible speed.
Yes you may have slightly less drag with a tail wheel.
The main problem is you can't see enough to keep it straight in a
full stall landing. One can learn to keep it straight if one had an
out side point of reference. The RV's are better as they have flaps
and are flown from the front seat.
The jpg illustrates a solution. It could also be done with a remote
video camera and monitor in the cockpit.
With all the slop in the tail wheel cable a Cub takes some learning just
to zig zag down the taxi way smoothly. I can't see out of the RV4
when taxing either but taking the slop out of the tail wheel cables
makes it much easier to zig zag so obstructions ahead can be seen.

Back in the 1960s, Vietnam era, the Air Force toyed with the idea of
resurrecting the P-51 with a turboprop engine as a ground support
plane. Â I believe some flying examples were built but the AF shelved
the idea because they didn't think they could retrain enough pilots
to fly a tail dragger ... and the P-51 did have a lockable tail
wheel. Locking it was on the pre takeoff checklist lest the torque
of the engine would steer you right off the runway on takeoff.
And shopping carts do make good trainers .... just put a case of beer
in one and have the trainee run it around the market backwards for
half an hour. Â Then they understand.
PS, I learned to fly in a military flying club at Ft Gordon, GA. Â All
we had was PA-!2 and PA-18 Cubs and a Cessna 140 and a 195 with the
Goodyear castering main gear. Â I never flew a nose dragger in my
first 100 hours.
SD
The purpose of tail wheel is so you can land on rougher field
without breaking off the nose gear. Â If you have the runway do a
wheel landing unless for some strange reason an RV lands better in a
xwind in 3pt than wheel landing. Â In wheel landing you can put that
wing down and land on one wheel just like trike gear to keep from
drifting across the runway. Â The problems don't start to arise
until tail gets low. Â If you try to 3pt in cross wind, its a real
bad feeling when you start drifting across the runway and your nose
is stuck in the air and you have very little directional control
because going too slow.
Van
There was a reason that prior to WWII the majority of airports were
large grass fields that allowed one to land into the wind regardless
of where the wind was coming from!
SD
Hence the use of the term "air field" instead of "air strip".
When I was learning to fly in a Cessna 120, this was only a few years
back, Paul told me that tail draggers where from a time when we had
air fields and you could land into the wind everytime.
I now have about 350 hrs, five of which are tricycle gear. About half
are in my Cessna 170B.
I ended up switching airports when I came home from a trip with a 90
degree xwind 23 gusting to 32. My new airport has three runways one of
them grass. 06-24, 12-30 and 18-36. 12-30 is grass. Grass will save a
bunch of tire wear. I have heard of guys getting over 2000 landings on
a set of tire on grass, and only 500 or so on pavement.

Man. If we had big grass fields to land on every where, you'd never haveto
do a wheel landing. 23 gusting to 32 was almost a typical day in Laramie,
Wy where I live most of time I had my 180. It was scary. Football fieldin
Laramie is over 7000 ft. Airport right up there. I never paid any
attention to airport altitudes. Always enough runway to get off even if
overloaded. The other place I lived when had 180 was Red Lodge, Mt. It was
over 6000 ft and strong winds there also. Paul will be fine in his RV4.
