Many pilots also a real B737 pilot told me the elevator feel force was too weak.

 I have now exchanged the springs with some double so heavy springs. (blue one)

In order to be able to change the springs, it was necessary to cut up the cockpit floor.
At the same time a good opportunity to have the control unit inspected after 14 years of faithful service hidden under the floor.

Measuring the max elevator force shows now almost 3 kg.

Potentiometers directly on controls replace my old "Joystick by Cable" solution

RC-links transfer Rudder Pedal movement to a  slide potentiometer (10 K Ohm/ 100mm)

Right Toe Brake potentiometer (10K Ohm/60mm)

Rudder movements are enclosed by heavy adjustable stops

Heavy springs centre the stick (elevator) and perform feed back called "feel".
In the real plane elevator feel is hydraulic computer operated.
