As the model by Warwick Carter was (re) painted by the late Garry J. Smith I had a small hope there was a repaint available at the Ford Tri-motor site we host here. But sadly I was unable to find a single repaint for the Warwick's T6.
One small remark; the fact that most people I know all fly the Alphasim payware version, tells me there is a significant quality difference between this payware version (I don't know the payware SkyUnlimited version) and the freeware versions.
For the FSX version I'm not sure which version I prefer as Warwick Carter's FSX version is pretty good, especially with John Terrell's repaints.
Cheers,
Huub
