Troy,
There was a conversion Ryan Hamilton (Hamilton Hobbies) did about 10 years ago now, Long OOP. This included GE engines, modified tail, aerial boom parts, drogue pod parts and a few ECM blisters and antennas.
On top of all that the kit needs to be shorted to an A330-200 (you can find instructions to do this on various forums for the location of cuts and how much to remove), the tail of the -200 is taller and broader in chord (so that is why a replacement is in the HH conversion) and needs modifying or replacing.
The other issue is decals, there has only been one set released which was through Southern Sky models (the sheet was maser by Ronin), again released around the same time as the conversion set. This set was limited to the general aircraft markings and none of the underside refuelling alignment makings was included.
Some pictures of my stalled conversion.
Fuselage mods
This was my first attempt, I was going to do a QANTAS A330-200 initially, I trashed this one and started afresh a few years later
Second attempt with HH tail
Boom and drogue parts (there were 2 versions, left boom and drogues are the later versions, the right side was the original release
