Is rudder required for coordinated turns?

Robert M. Gary writes:

It depends on the plane. High performance planes almost always have
rudder interconnect. Planes like Arrows, Mooneys, Bonanzas, etc
automatically move the rudder when you roll the ailerons.

Do you feel this in the rudder pedals? Also, do you still have
independent rudder control? That is, can you inhibit the automatic
rudder movement, or increase it?

I'll look at the sim aircraft on the ground and see if the rudder is
moving with the ailerons.

However, if the J-3 simulation acts that way, the sim developer doesn't know
what he's doing.

What is J-3?
