Dear Bill, Ed, John, et al.
Found the discussion most useful. My first `coupe had the "aerodynamic"
trim,
which consisted of a lever on the left side of the cockpit and a wire going
back
to a movable tab on the back of the elevator. My new-to-me Ercoupe has the
"intermediate" system of a crank, a cable, and a spring pulling down the
elevator.
From this pilots perspective, the aerodynamic provided an intuitive and
stable
system. With the crank, I am always trying to balance the engine RPM and the
trim setting. It would help if the vernier throttle did not vibrate open as I
cruised along, though!
