There is a package over at flightsim.com that includes the model and a TWA livery. As with most TDS birds, they really need to have a panel and sound alias'd to them. This one threw an extra curve in that there is a modification to the aircraft.cfg file needed to make the artificial horizon work:
You need to make the following change in the aircraft.cfg to fix this:
[attitude_indicators]
attitude_indicator.0 = 1
Change it to:
[attitude_indicators]
attitude_indicator.0 = 2
Have only done but a couple of touch-n-go's so far, but she looks promising.
