You know Jeff, that makes a lot of sense. I think that might be another piece of this puzzle.

Personally, I am beginning to believe the issues some of us have experienced were probably related to caster angle, spring tension, rudder deflection, gear alignment, or any combination of all of the above.

More and more I'm starting to think that someone really needs to make it much clearer to builders and flyers just how critical any or all of these things can be to sucessfully operating a tailwheel airplane...

It would be nice to see the tailwheel manufacturers do a better job at providing that information proactively, rather than to let some learn the hard way...

It would only ever have a tendency to make the airplane turn, if the
caster angle is incorrect.

So I would assert that if an unlocked tailwheel is causing the plane to
go off course, then the caster angle of the tailwheel is incorrect.

The exception to this is if you are countering a strong crosswind on the
ground with the tailwheel, then it unlocks and rudder alone cannot keep
it straight.
