The Great Planes Easy Sport is a shoulder wind second plane type.

Some aileron differential should do no harm, IMHO.

The AOA increases during turns, so the fuse should pitch up some.

If the incidence angle is incorrect (too positive), the tail-down effect will be more evident.

If what you see is yaw deviation, then rudder is the only way to coordinated the turn.

CG location has nothing to do with this problem: planes that fly and land in one piece are more or less nose heavy, but are never tail heavy.

You are correct, with the extended nose, there is more side surface aft the CG that is fighting the rudder in a coordinated the turn.
