Would I be correct in assuming the Scott 3200 utilises the standard Stinson leaf spring..?

Thanks for the confirmation... I have another question though. My recently acquired Straight 108 (an aeroplane I am increasing more impressed with as time goes by, knew nothing about Stinsons when I bought it..) has the Scott 3200 tailwheel fitted with Scott springs. I am curious to know how the community sets those springs up..? Slack..?, tight..? or somewhere in between..? I am based on a grass strip where I'll be doing most of the flying, but here in NE PA there are many hard surfaces to visit, so I'll be operating off those as well.

Any observations are appreciated

No slack, but not tight.

Al,
When Matty owned the airplane it had the wrong steering springs on it that I noted from photos. I encouraged her to get the large spring kit, P/N 3239 and install them or have them installed to be no slack but not tight. I thought that had been done.

It has a single Scott spring (don't know the p/n), that is under tension both sides when the wheel is straight - it's about 3/8" too short. The attachment loop has been bent in an attempt to lengthen it, but from what you and others say, I think I need to hunt down some new ones. The springs are also wearing an oval hole in the steering arm, so I'm thinking of putting a small eye-bolt in the arm and hooking the spring to that, don't know if that would upset the geometry or not though.

Al,
The Scott part number for the correct springs is 3239. It is a kit of two from Spruce and or Univair and comes with chains and clips.
Springs are to be installed not tight, but all slack removed. Tight wears the rudder. I thought it had been fixed by our "Friend" that I think bilked the former owner.

It is now owned and sold as Bush Master but they kept the same part number and are the same parts.

Thanks for the info - UPS will be by soon - again...

Yes, he did "fix" it with new springs, but they are tight and there's wear on the steering arm from the spring steel pulling on the softer metal of the arm, and I need to take care of that sooner rather than later or I'll be buying more parts from Earl..
