G'day from Australia



Ok! Who has got a Scott 3200 in their workshop that they don't want?
Any clues on one would be appreciated.

If it's for a homebuilt you might do better building your own. I
recently had to replace the 3200 on one of our Citabrias, and I got a
"deal" at $1100 (Canadian). It was new, but old stock; the dealer
quoted a current price of about $1500 for a new one.
It wasn't too many years ago that they were around $700. Did Scott
lose a big lawsuit or something?
Somewhere a few years ago I ran across an article that had plans
for a homebuilt tailwheel. I didn't keep it, and don't remember who
published it. Maybe someone here does...

Heck, you can buy a Maule pneumatic which works as well as or better than a
Scott. Much cheaper too, at less than $500, and what can a Scott 3200 do
that the Maule can't do?

G'day Dan

I have a Murphy Rebel with the standard factory tailwheel, but it has worn
badly in just a short time.

What I might do is make some major alterations to it to make it more
durable. But having seen just
how robust the Scott 3200 is I would really like to replace it with one of
those.

G'day

Well I have never seen a Maule wheel before. That is something to consider.

How do you consider that the Maule would be better than the Scott, apart
from the cost?

I think it's the other way around...what can a Maule do that a Scott
3200 can't do? SHIMMEY! Years ago we put a Maule pneumatic on our
Cessna 140 to replace the hard rubber tire Scott 2000. Never could get
the Maule to work well, so we went back to the Scott. The other thing
that is nice on the 3200 is dual forks. That just HAS to be better than
a single fork in rough field operations...

I should have kept the Maule a secret because now everybody will want one
and Maule will go up on them like they have on the Scott. Anyway, I have a
Maule pneumatic swiveller on a Super Cub and it is very robust and easy to
repair and to grease. Plus parts for it are cheap and readily available.
I put a new non-pneumatic swivelling Maule tailwheel on my Taylorcraft ten
years ago, and hung up the old Maule non-swiveller, and it has performed
flawlessly. People who have trouble with Maules,other than from just
ordinary wear and tear, usually let them go without grease. And then the
tire will wear unevenly and not caster correctly if your tail-springs aren't
shimmed for book geometry. You can see the exploded view of parts of this
tailwheel at the ACS link attached to my earlier reply. It is very easy to
maintain and repair, tapered roller bearings and all.

OTOH, I do like a Scott and see its many virtues, but for the money I'll go
Maule any old day. $1500 for a new 3200 is for suckers.

Last night I talked to a friend who paid $75 for a used Scott 3200 a decade
or so ago and (being adept with the lathe and milling machine) rebuilt it
for use on a Marquart Charger. I told him he stole it. He said that
although it had been a good tailwheel it didn't impress him all that much.
I'll have to see what tailwheel he's using on his latest taildragger
homebuilt. I'll bet you a dollar it ain't a Scott.

Scott, I have seen those Scott forks bend, warp, crack, break and be
re-welded. Knock on wood, but I have never seen that big brawny fork on a
Maule crack or break. I have never had a Maule shimmy on my aircraft, but
have fixed a Cub's Maule that shimmied because the tailsprings had been
improperly installed and the wheel was mis-rigged.

Let's hear it from the bushplane boys in Alaska. That's where a tailwheel
does the ultimate duty.

BTW, a friend just got back from ferrying a VG'd two-ten to Wasilla, AK.
He said on the destination airport was an old Taylorcraft with a two-hundred
horsepower Lycoming on the nose.

One of the Fly Baby crowd put together a paper on the care and feeding of Maule
tailwheels:

http://www.bowersflybaby.com/tech/Maule_Tailwheel.pdf

He recommends dissimilar springs to discourage shimmy, and says that binding or
looseness in the assembly itself encourages it.

Myself, I haven't had a problem.

Excellent site, Ron. Just what you need --- the vertical shaft tilted 15
to 20 deg. forward, compression (not tension) springs with asymmetrical
recoils, the assembly rigged true at the leaf springs so there's no lateral
tilt of the wheel, and no slop in the leaf springs or chains. If there's no
slop in the wheel assembly you won't get any shimmy.

In 20 years I never had a shimmy. Last time I was at Clemson I watched a
Skybolt land on the paved runway. He should have landed in the grass. The
aircraft had a Scott 3200 on it. The shimmy was so violent it was awesome.

But then he probably just had a rigging problem.

[Scott]

WoW! That's not a Taylorcraft, that's SPACESHIP 2 :)

That sounds like it could be a fun ride!!

Here goes the old debate again. Are we talking the top of the
pivot axis tipped forward? Every tailwheel shimmy I had was partly due
to that, and replacing the tailspring or whatever to get the axis
vertical or tipped back a little stopped the shimmy. It's the same
effect as a bent caster on a shopping cart: bent back, it will shimmy.
Now I know that there are some aircraft manufacturers that specify
the axis tipped forward, and I don't know why.
The Scott we bought recently was to replace a shimmying Scott.
We had replaced everything else related to the tailwheel, had the axis
fixed and everything, and it still would not stop. It turns out that
the bronze bushing in the fork wears out, and Scott doesn't sell that
part separately; have to buy the whole fork, which costs a big bundle.
To avoid any further fooling around, we replaced the entire assembly
and the shimmy went away immediately.

Well, I don't tip it quite as much and see them work fine when not tipped.
The more tipped the greater stress on the bushing, of course. Then when it
wallows out you get shimmy invariably.

Paying big bucks for that fork assembly is a little painful, isn't it?

How much was it and where did you buy it? I know somebody who needs one
very badly. He shoulda had a Maule.

I have the 6" Maul on my Jungster II. To cure the uneven tire wear I
replaced the Maul wheel with one of the ones ASS sells for the
homebuilt tailwheel unit. It has a metal hub and has less tendency to
run over. You can frequently get the same wheel at a industrial wheel
supplier. Check your axle size as they come in two different bores.

Sure is - I got mine 3 years ago on E-Bay - never installed but
several years old, for $275.

G'day

Thanks for your considered response. I have never seen the Maule tail wheel,
but I will have to get out to the local
airfield and see what the taildragger people are using.

I agree that the cost of a new Scott is extreme!

I got the last old-stock one from Aviall. The next guy has to pay
the shot.
I was quoted as high as $1750 Canadian for one from various
distributors. That's about $1400 US.

Bless you, brother. Confession is good for the soul. In addition to
which you got a taildragger there with Moultrie, Georgia class.

[Jason Grass]

The main advantage, or probably the only advantage of the Scott is the
dual fork. I wonder why Maule doesn't develop a dual fork unit also. I
have a 3200 on my homebuilt, and have only had one problem with it,
shimmy. And that was due to the springs being loose, and the friction
nut not being tight enough, added to that, a rough runway that incited
the shimmy. It wore all the tread off the tire down to the cords.
If I encounter the worn bronze bushing mentioned earlier, I'll get new
ones made up at a machine shop and have them installed, before
purchasing a new fork from Scott. One of the nice things about
homebuilts, not being at the mercy of a PMA requirment madated by the
FAA.
