I recall many decades ago, large radios had flywheels on the tuning
knobs. Partly this was because they had large dials that went over a
large tuning range (like close to a 3 to 1 frequency range - this is
the AM broadcast band range, but it's a huge swath of the shortwave
bands) - the tuning capacitor turned 1/2 turn, but the tuning shaft
was geared to go maybe 10 turns. The flywheel helped keep the knob
spinning to help get from one end to the other faster. Even when this
wasn't necessary, having a small flywheel helped with the "feel" of

One might try that, but I'm thinking the haptics of something
physically moving is an important part of this sort of thing.
