The last one for today. I designed throttle linkage. I might extend the arm of the bell-crank to increase resolution even more. Right now the full travel is 1/2 inch. As I have zero slope on the bell-crank (it has bushing taken out from CR-ROM motor

) I want the best resolution on the linkage as I can. I will have slope on the servo linkage because the cable needs to be quite long.
Pictures attached.
