I did a couple tests with Jahn's C-47 and C-117D.
The C-47 worked fairly well for me, however since the autopilot in the VC in inop and the popup 2D panels don't work I can't use the Control Panel to set the autopilot and no GPS to navigate its going to be hard to use. And like many of the tail draggers I have tested it went nose over when I tried to stop it.
None of the gauges in the C-117D worked as you can see.
One thing I did noticed, when you start then you need to give them some gas right after loading or the engines will stall, and if you press Ctrl-E to restart them, CTD.
