smArtcontrols manage datarefs and art-controls based on the simple and light xLua plugin from Laminar Research.
It does NOT require third-party libraries or environments to work and has basically NO cost on the framerate.
Just put it in the Custom Scenery folder and forget!

* The scripting system allows to easily add other functions based on future needs or developments, as example if and when Laminar will improve the cockpit exposure natively, we will easily adapt our script to take advantage of this.
