There is some friction.... The throttle feeling is already perfect because I mounted the friction rollers. Aluminum discs and leather, pressed together by a spring. Why leather? Because the first cars had brake pads made of leather and I had nothing better in my workshop. And it works wonderfully. The potentiometers are still missing and178 other parts until the throttle console is finished.
Yesterday I put a new gear wheel into the elevator trim indicator (the disc with the numbers) and now this works too. Ba chance I had a suitable gear in my collection. The only problem was to turn the round hole in the middle into a hexagonal one. But with some time and a file even that is possible.
