Hi Troy,
As far as I am aware, you have three decal options if you are wanting to make a Qantas 1:144th A380
Option 1
Hawkeye Sheet CDS-111This sheet presents a representation of the Qantas A380 as it would have appeared in the pre-2007 corporate colours. Please note that the Qantas A380 never actually carried this scheme as, by the time the first aircraft was delivered, the change-over to the current scheme had occurred. It would none-the-less make an interesting model though, as these are the colours that were depicted in much of the promotional material when the A380 order was announced, and leading up to delivery.
Hawkeye may have an up-dated A380 sheet coming.....Scotty????
Option 2
TwoSix Decals Sheet STS4475If an updated Hawkeye sheet is not yet available, then this is the sheet to grab if you want to represent the model you are building in the current QF colours, (and as the aircraft were delivered) .
Option 3
TB Decals Sheet TBD76This sheet was/is freely available on eBay, and is designed as a supplemental sheet to be used in conjunction with the existing kit-supplied decals. Note however that you only get one rego, (VH-OQB), and the "Airbus A380" titles are the wrong font style and colour. Also, one of the Aussie flags is incorrect, (the Union Jack should always be at the leading edge of flight).
Hope that helps.
