Scott 3200 tailwheel

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.

Amen to that!

that is nice on the 3200 is dual forks. That just HAS to be better than
a single fork in rough field operations...

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.

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

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.

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

That sounds like it could be a fun ride!!

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.

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.

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 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.

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

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.

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 would also like a "project wheel if one turned up!
