Looking for a unit like this but 100k the maker's only do up to 30K it is a child's battery car accelerator.
Fitting does not matter it is the strait movement, any ideas?
A rotary pot is fidley & brings other problems. to use rotary
Chinese box not going to trace circuit cheaper to buy new box with thumb speed controller.
Did think of that @Julian but in a child's car so wet & abuse, sliders are not that robust usually unless you know of heavy duty ones in your game
You could put three wired in series to get 90k? If they are small enough to fit.
Likely to be a slide pot and a spring inside. Open it up, replace the pot?
