The designer of my fave taildragger has the ground-steering parameter (contact point zero, 8th value along) at 60, which seems pretty frisky. I've dropped it to 30, which seems better, but if anyone has a more defensible number I would appreciate knowing.
I have a feeling that this is the sort of question that, after you fight through the dragons and morlocks and whatnot, the wizard holds up a mirror and says, "The answer is within you."
But if there is some rational argument, I would really appreciate it.

Scruffy, Sit.
My experience with this parameter has been that it seems to always be too high with most aircraft and you reset the value at will depending partly on your control sensitivity settings. It is very much 'suck it and see'. If it feels good it IS good.
Good boy, I'll get some shampoo! Ed

Well, if you want to call yourself a dirty dog we'll treat you accordingly. You'll note most of us go by our given names.
In real life the tail wheel steers 90 each way! You get that by locking one brake and horsing the throttle - the outboard throttle if you have two . You don't drive a taildragger straight anyway. You swing 30 deg each way until you get ready to move up to speed on the runway. Then the propwash on the rudder keeps you straight until the tail really starts flying.
You should give yourself a dose of reality once in a while by setting up a crosswind or using Real Weather which usually gives you a gusty crosswind. Enough of that and you'll convert to a nose gear.

Of course I had no influence with the Nickname Selection Committee, who are perhaps overfond of irony. Frankly, I am surprised it has taken this long for some gentle kidding.
If our friend Mr Ed wants to kid me, in return for the useful info he ususally gives, well that;s a good deal for me.
The business about Dose of Reality in the context of FS is just too easy, Pass.
Nosegears are for wimps

Okay we'll talk about a dose of reality. This sim allows the introduction of elements found in reality in measured amounts. "Nosegears are for wimps." Tail wheels will prove very difficult to land if you introduce crosswinds. And if you introduce some gusty conditions, forget it. You won't get the plane back to a parking area. When you fly in Real Weather (downloaded from the Internet), the conditions are close to what you would find just about every day in the real world - slight to moderate gustiness and a wind across the runway. Tail draggers are tough to land in such conditions.

The default FS9 DC-3 had the steering parameter set to 180. That was an error on Microsofts part, because at full rudder deflection you went straight ahead! I have my tail draggers set at 90.
Most of my tricycle aircraft have the steering parameter set between 25-45 degrees. I almost never change them.

This Fairchild F-91 is great in the air , but to Taxi on water it will only turn right and not very well at all. On land it will turn slightly left with full left rudder. Has no diffrentual breaking . I like the beast , would love it if I could taxi. Is there an area I can simply adjust in the aircraft Config.
update ;Tried changing contact point 0 station 8 which was at 40 to 80, no help.

Hi David, Well, the F-91 sure sounds like a beast. You may have already tried this, but to be clear, as an example: Look in the config file for the Goose in the [contact_points] section, look for contact Element 5 (water rudder) See below Position 8 is the steering angle. Looking at pictures of the F-91 the water rudder is just behind the tail wheel, as expected, not sure if it retracts or not. I think the "W" key controls the water rudder retraction/extension. Allen
position 1 2 3 4 5 6 7 8 point.9= 5, -6.5, 0.0, -6.0, 0, 0, 0.0, 20, 0.00, 0.0, 1.00, 0.0, 0.0, 0, 0, 0

Thank You Allen , I copied the contact points from several sea planes on paper all with single engine , two with over the wing motor position. studied for a bit then made changes to the F-91 Configuration . I had no luck , maybe it is in the Model or Air File. My best quick fix is to aim left on take off using MAP or slew, and use right turn taxi ways. Got a hanger now full of Amphibians so I will find something to Rally in.

So you're probably tired of dealing with it, but just curious, with the plane in the air go to an outside view and see if the water rudder actually moves with the rudder pedals. Looking at pictures of the plane, the water rudder seems a mite small. Maybe it never did work well. There is always the Goose. Allen

Allen , the water rudder an tail wheel move with the rudder in flight views. I looked at 5 different Amphibians ,and all on floats show water rudder movement , the sea planes do not but still respond well on taxi an take off( rudder input corrects torque an P-factor) . It is a gremlin.

I have never flown a single engine off the water, do the water rudders work in the payware Beaver ?
When flying the Catalina off the water I use differential engine power for turning, she turns slowly as the real aircraft does, having the engines so close to the aircrafts centre line. Once you get the pointy end in the correct position for take off she is very straight and stable during the take off.

Do not know about the Payware Beaver , but enjoy the Catalina.
