There is no traditional paint kit included with the Duchess Model 76 (X-Plane 12) or PA-28R Arrow III (X-Plane 12). Instead, the products feature the "Dynamics Livery" functions on the EFB that allow you to create liveries within the simulator, and the models can also be painted in 3D using software such as Blender or Substance Painter.
I have just noticed that a paint kit is listed on the product page so I have contacted our marketing team to update that accordingly. We apologise for the confusion caused.
