Euroastar350 is working on the native FSX S2T Civilian Tanker, or has it in his list to do after his release of my C-1A Trader which was last month.
Please see the most recent updates in the "Where did the .com name go?" thread. Posts number 16 and 17.
Just FYI, but I've got one C-1A almost finished with some more in the pipeline.
BuNo 146027 is pretty much complete, just needs final inspection, making a thumbnail and packaging it all up.
BuNo 136754 is about 2/3 done. Actually just need to do the nacelles and cowlings, but on this one, those are going to be some of the toughest parts.
There's a couple more Navy ones I want to do and then some fictional civilian ones (The Trader should make one heck of a bush plane)
Willy, there is a cargo version of the C-1A, not native FSX however. You can click on the link in my signature to pull it up.
