Is it possible to assign an activation group for the RPM governor from the electric motor? It can be tricky to click the electric motor in flight for some designs, so it would be helpfull if that were possible.
Also is there a way to get the propeller RPM some way? I want to display it in the cockpit in flight.
For getting RPM: https://wnp78.github.io/JunoXml/ see PartModifierScriptProperties. You can call any value from that category in Vizzy via a fUNk block, and I don't believe this risks a craft's mobile compatibility... though I might be wrong. You can also just call that through an inputController, which makes more sense for a dial, but then there's no guarantee that mobile players can use it.
