Tailwheel Steering Arms

What kind of tailwheel steering arm do you have? Mine is cast steel?? and fits
over the rudder spar tube. I'm not crazy about the design so am ordering a Scott type of cast Al with a 3/4" post that fits inside the rudder spar.

I see no reason this won't work better because I can use thicker walled tubing to mount it in and make this end of the rudder spar stronger. As it is now it is 1" x 0.035" tubing, not very strong at all. My steering arm bolts ripped out the rudder spar holes and bent it back when I banged the rudder on the tailwheel.

Gus,

Nothing like that on my plane. Mine is cast aluminum and while I do not have the size handy, its not a standard size either. Believe its something like 11/16th's or 7/8's and not sold by ACS or Wicks.

Fits up inside the rudder post. Held in place by one bolt, believe an AN-4 but not sure.

Gus,
ACA makes a nice steering horn for the Citabria that will fit. The original bolts were 3/16. If they are allowed to run loose, for any length of time, they generaly need to be opened up to 1/4 to get a round hole again.

Paul and Joe,

Thanks. The one I'm ordering has a 3/4" shaft and fits inside the rudder post. I think it has two bolt holes, it is made for or by Scott according to the Air Spruce catalog.

I don't like this heavy steel outside mount thing. I can't believe one of these would be made of steel but it is?

I just looked up the Scott steering arm I was planning to by on the Air Spruce website and the price is $279.95!! Is Scott Co suffering from some kind of delusionment?

The catalog I have says $38, much more reasonable but it appears to be a misprint, it was probably supposed to be $380.

Needless to say I'll buy the no name one under it for $36.10.

Gusc,

Might want to call them, are you looking for the RUDDER ARM Scott PN 1140 about $65.00 or the Fork for $275.00?

Mike,

Here is the link;

AS calls it a rudder arm.

In my AS catalog it is listed as $38??

The Scott Fork is p/n 3224 @ $318.95!!

The Champ is a funky size - 7/8 seems right. They do make them, but it took my mechanic a week or so to track one down for me. They're PRICEY - seems like I paid about 6 times the price of a Cub arm.

Yes, Scott is suffering from something. Have you priced a 3200 tailwheel lately?

Not only is the Champ arm a funky price but it is a funky shape. It drops down about eight inches compared to about an inch for others. The full rudder clearance is very small also.

This must be the reason for the price.

There is a Scott fork on Ebay right now but its too large to fit inside the rudder post on our planes.
