 Paul, Didnt read but article with heading about Beringer making
ground loop proof tail wheel that works with rudders.  I doubt it:-)

Saying and doing are two different things.  The physics works against
him.  Tail wheel airplanes will always want to ground loop because the
fixed point of contact with the ground, the main gear, is forward of the
center of gravity of the airplane.  It must be thus so that the airplane
will not end up sitting on it's nose with a twisted up propeller.  I
suppose you could move the CG ahead of the main gear if you had a pusher
configuration, but then getting it to rotate and lift off would not be
easily accomplished.

I plan on obtaining or building a cockpit lock and unlock tail
wheel for the RV4. If you nail the tail in no cross wind the feathers
are behind
the arrow head :)

Paul,

Check this out:

They make both a 4 and 6 inch model.
The P-51 had a locking tail wheel.  The way it worked was that it as always
locked unless the stick was all the way forward.  You can still steer with
brakes and rudder, to a degree and you can see over the nose of the RV-4 so
you don't have to S-turn.  When you have to make a sharp turn, you come to a
near stop, put forward stick and use brakes to steer then back on the stick
to lock the tail wheel.

Yes I saw that but for the money I think I can build one just as good.
