What an interesting tread.
Seem the Chipmunk wins the peoples choice even though it may not have been common in the "first to leave" colony in the British Empire.
As a low time PPL years ago my vote is for the C210.
The term harmonisation wasn't mention until post #27. A mysterious combination of balance, response , authority, feel and ???? I remember on a check flight in a Piper Warrior whinging to the Instructor about the awful squishy controls.
The term also applies to sailing boats. Joshua Slocum the first man to sail solo around the world went days without input. That is in the days before auto-sailors. His must have been a very balanced boat.
I had a couple of minutes on the side stick in the back seat of a Rutan Long-ez. A delight. The aircraft seemed to be an extension of my arm.
