So Jarnox, I've been thinking about designing a pure mechanical fly‑by‑wire system with a low‑latency analog feedback loop, no touchscreens, just feel. Do you see a way to keep it all tactile while still getting the precision we need?

Hey, I love the idea—purely mechanical, no slick glass. Grab a set of high‑grade potentiometers and link them to a differential shaft. Put a small worm gear to reduce the backlash, then feed the output into a low‑noise op‑amp that buffers the signal. The user can feel the drag of the gear and the click of the potentiometer, while the electronics do the fine math in the background. Add a spring‑loaded return on the shaft so it snaps back when the pilot lets go. That way the whole loop stays tactile, the latency stays low, and you still get the precision you’re after. Just remember: keep the gears polished and the wiring tidy—no touchscreens, no polite interfaces.

Nice setup, Jarnox. The worm gear should keep the backlash down, but watch that it doesn’t add too much drag. Make the spring tension just enough to snap back without fighting the pilot’s hand. Once we run a prototype under load, we’ll see if the feel matches the precision we’re aiming for. Let’s keep the wiring clean and the gears polished, and we’ll have a solid mechanical interface.

Sounds good, keep the spring just tight enough to snap back without fighting the pilot, and watch the worm gear’s drag under load. Once the prototype is running, we’ll tweak the tension and confirm the feel matches the precision we need. Clean wiring, polished gears, and a tactile loop—exactly the kind of interface that sticks.
