The reason is because on those designs the static Cg is only
slightly ahead of the main landing gear. Without the pilot aboard
there is a very real risk that a gust of wind will tip the
aircraft back onto its butt. Collapsing the nose gear when parked
shifts the Cg forward.
The next question you're going to ask is "why don't the builders
move the main landing gear aft?" Two possible reasons: moving the
gear aft might make unsticking/rotation on takeoff a much too
exciting event (think uncontrolled stall on takeoff), and the main
gear has a tendency to throw up runway debris which we'd rather
not have pass through the propeller disk.

With the nose on the ground it becomes almost impossible for anything but a
near-tropical-storm-force gust of wind (or higher) to move the airplane.

So, why doesn't some clever builder make the main gear swing back when the
parking brake is set and swing forward again when the pilot is in the
cockpit and the brake released?
That would solve a lot of problems with small pushers.

Three reasons.
Weight, weight, and weight.
Why not do what they have been doing, and not add 1 extra ounce?

Another may be that if main gear is moved aft a more heftier
front NG would be needed. Keeping most of the load on main gear keeps
the cost down.
Dont know why cozy's, MK IV, etc. don't spread the main gear more.
The main RG on my SQ2000 is 11' apart with little chance of
throwing debris on the 66" prop.

I heard many years ago that the nose on the ground put the cockpit
rail down where you could just step into the cockpit and then crank
the nose gear down to take off position.
Without this you would need some type of a boarding ladder to get in
and out of the cockpit.
Anyone support my memory?

IIRC, the Rutan canards are a bit tail heavy with ethe gear down and
nobody in them. They are stable with the NG retracted and nobody in them.

I've been in a Berkut where the owner did this (electrically
actuated gear) but I can't imagine doing it with manual EZ gear.
Of course I couldn't imagine doing it in the Berkut either, but
he insisted.

No ladder necessary for most folks. EZs have a step that facilitates
cockpit entry with the nose gear extended. It's sort of like mounting
a horse by putting your foot in the stirrup.
Here is a picture of my plane and the step,
http://www.airplanezone.com/Oshkosh/Scrapbook2002/Images/DSC00517bSM.JPG
Left foot on the step, left hand on the longeron, right leg up, over,
and in. As for rear seat passengers, entry is no problem for the
young and agile but sometimes problematic for older folks.
The nose down parking position is sometimes referred to as the
"grazing position", which is especially appropriate when parked on
grass. :)

Beautiful bird. You do good work <G> And take good pictures.
See the step but don't remember ever seeing on the original
plan/birds????? which I looked at years ago for possibility of
building. May have missed that minor detail.
The EZ had a carnard/rain problem. Is that fixed now or do you have to
fly around the problem?
Have seen lots of figures. What's your HONEST cruise at say 8K?

Never mind the rain problem, friend who has one got a couple of
youngsters to wash his down, he spent the next hour moping out inside
the cockpit. They used a power washer to get rid of the shampoo and
wern't too careful where they directed the spray.

The step on my Long EZ is per plans. I don't know what kind of step
the Varieze plans called for, if any. Maybe someone with a Varieze
could chime in. I'd like to know.
>The EZ had a carnard/rain problem. Is that fixed now or do you have to
>fly around the problem?
Well, it's not fixed on my airplane. If I want to fix it, I have to
build a new canard. The effect can be trimmed out. Variable rain
requires frequent re-trimming, of course. I largely avoid flying in
the rain because of my wood prop. Interestingly, the canard will let
me know it's raining even when the rain is so light that I can't see
it. It's my drizzle/virga detection system. <g> On several occasions
it has clued me in to virga that I would have been oblivious to
otherwise.
>Have seen lots of figures. What's your HONEST cruise at say 8K?
I get 162 kt TAS at 8,500 full throttle leaned for best power. The
engine is a 150 hp O-320. I have wheel pants in the hangar that would
give me another 5 kt or so if I would only install them. <g> Plus
there are a number of other things I could do to clean it up
aerodynamically. Interestingly, the boarding step alone knocks close
to 1 kt off the top end.

I'm not racing anyone until I get a new prop, install a spinner,
install those damn wheel pants, and do a few other aerodynamic
cleanups. Maybe next summer if you are still game. In the meantime,
you could pit your 150 hp RV-3 against Klaus Savier's *120* hp Varieze
and get your pants blown off today. :)

P.S. Klaus Savier came in fourth this year at Reno in the Sport Class
Silver race in an O-200 powered Varieze. His average lap speed was
216 kt. This was just 6 kt slower than third place finisher John
Harmon in his 400 hp O-540 powered "Harmon Rocket III", an RV-4

Sure, and....
I want to race in NASCAR with a show room Ford, Chevy, etc, too.
However, I might consider racing Klaus out of a 700 foot
super rough sod strip with 60 foot trees on each end. <g>
There are RV-3's running with aerodynamic mods that bump the
speed up, but I'm not in that group and have no plans to be.
Currently, I have no spinner and have just changed props.
It is not as good for racing as the wood one I had.
Sounds like a fairer test could be had now, not later. ; (

There is a lot to be said for elegance.... and brute force.
If I was racing, I'd like both in a project.
Perhaps you have some ideas about the flat plate
areas of these two aircraft... that didn't win 1st place?

How much more horsepower, money and RPM's would

Racing one handicapped plane against another doesn't exactly float my
boat. I either race with my plane in good form or I don't race at
all.

Let's go with 216 kt -- I don't know about the money but the power
would have to be somewhere around 220 hp with my plane as it is now.
Significantly less if cleaned up. As I am having trouble getting
motivated to even install wheel pants, I just don't see Reno in my
future. :)
As I have noted before, I think the RV series is a marvelous design
and better in many respects than the Long EZ. Indeed, even Burt Rutan
concedes that "the prop belongs in the front." Nonetheless, don't
look for me to toss my old bird to the heap anytime soon.

If having the propellor on the front were such a good idea, how come *NO*

Boats don't fly very well. Wilbur and Orville found that trying to make analogies
between boat and airplane propellers was totally useless. Nobody's proved them
wrong yet.

OK, humor aside, why should it be that comparisons between the regimes is "totally
useless". Both devices impart a force parallel to the axis by moving a mass of the
surrounding fluid backwards. While the obvious differences in density and Reynolds
numbers makes comparing airfoils to hydrofoils dubious, it isn't obvious to me that
comparisons of "ended-ness" are invalid. Can anyone explain why?
For a point of data, I believe that some new very large vessels (cruise ships? VLCC?)
have multiple propellors that, while being very near the aft of the vessel, are mounted
on pylons such that the blades preceed the pylon through the water. I have to imagine
that the engineers must have a reason for doing so.

Would this work? Getting back to the CG issue.....How about having
the nose gear PARTIALLY retract. The nose gear would have 2
positions. Position 1 would have the plane in the PARKED ( partially
retracted ) position. The plane would be level or slightly nose down
to facilitate easier boarding. The main gear would be far enough back
so it wouldn't tip over on it's tail when no one is aboard. ( Velocity
) For landing and takeoff, put the nosegear in the EXTENDED
position.( Position 2 ) The CG would move a little more aft, but more
importantly, the plane would be at an increased angle of attack to
facilitate better take offs and landings. That way, the plane
wouldn't have to rotate so much to get airborne and on landing, the
plane wouldn't have to "slam" down so hard (far).Just a thought.

I have read a few books on boat design. The only author
that said anything about front versus rear propellers
thought that a front mounted propeller would be slightly
more efficient. He then stated that he would never put one
on the front of a boat because accidental groundings and
collisions with debris floating in the water at or just
below the surface would damage or destroy a front mounted
propeller. A rear propeller is protected by the bulk of the
boat as it moves through the water.
I doubt that any aircraft designer feels a need to concern
himself with debris in the path of a flying airplane.

Good point, and the "nose on the ground" approach is arguably the best
solution. Just a matter of preference I guess. I'd just rather not
park my plane with the nose on the ground.

Unless you're the guy that designed the Space Shuttle.

It's only an issue if you don't have the plane tied down. Use a nose tie
down and you don't have to park it with the nose on the ground.

Actually, the reason behind my post if the first place was to solicit
a response letting me know if my idea would work or not. I know it
may not be the BEST solution, but I thought it WOULD work. I have not
talked to any Velocity drivers, but from anything I've read about
them,( the plane...not the pilots ) they don't seem to have any bad
takeoff or landing traits, so I'm curios as to how they are able to
park their planes without their "noses on the ground" and still have
the good traits assuming their empty weight CG is so far ahead of the
main gear that prevents a backward "tip-over". I know that sounds
wordy, but I think you understand my question. Thanks

Neal,
The Velocity's have quite a bit more weight on the nose gear that the
typical EZ's do. The Velocity's are able to get away with this because they
have much larger canards (relative to the wing area) and slotted elevators
(like fowler flaps) which allow them to rotate at a reasonable speed. They
do have considerable runway runs, like all canards do, both take off and
landing.

Sure do, and....
I hope you understand my tongue in cheek

I understood. Sometimes I come up with a " I wonder if this would
work " idea and I find the RAH group a good sounding board. I even
got a great physics lesson from a fellow poster the other day
regarding the construction of a wing spar. Great stuff..............
