Is rudder required for coordinated turns?

Yes. The rudder pedals move with aileron control inputs. And yes, they can
be moved independently of the ailerons due to the spring configuration. It
makes slipping down final in a crosswind a little more difficult since you
have the usual control forces due to aerodynamic pressure plus the pressure
applied by the springs. That's why I prefer to crab down final and
straighten out just before the wheels touch down. That's also easier on the
passengers.

A J-3 is a Piper Cub.

That takes me way back to sideslipping DH82's when rudder was used in
bucketfulls :-)

It depends on the plane. High performance planes almost always have
rudder interconnect. Planes like Arrows, Mooneys, Bonanzas, etc

My Beech Sundowner has an interconnect, but you still need a tad of input.

I'm pretty sure Arrows don't have an interconnect, but I only know about
the standard version, not the T-tail.
