So, someone could tell me how to configure properly the speedo/tacho needles? Like, how can i calculate how many KM/h is a certain value in the jbeam, or somethink in these lines? Or at least tell me how can i make the needle show correctly the ~120km/h mark (with limit to 180)?
I don't think this is your biggest issue right now, but here's how to do it anyways.. Find the "props" section and find the speedometer gauge (example: ) Define the maximum rotation the needle can do (just eye-ball it, it takes time) then define the min/max and the offset/multiplier (used for fine tuning the value control).
