There may be some minor line issues here and there but there was no paint kit for the KBT Electra and the textures were different between the passenger version and the cargo version. One major issue which cannot be fixed is the fact that the Cargo door is at the front left hand side - which is the way KBT modelled them. The Ansett freighters actually had the door at the rear on the left hand side, this cannot be changed alas.
There are also changes to the VC cockpit lighting between the two. One is redder and the other more yellow in tinge.
Anyway as is - enjoy the Wombats.
