Having a hard time trying to use the auto pilot on the retro panel of the DC-3. I have the latest version of the Duckworth mod installed. I start the engines open the hydraulic valve, move the handle. I turn the radio Nav 1 to VlLOC and VNAV. I  take off and engage the auto pilot and tick on the heading and altitude hold buttons. The plane turns to the east and flies straight and level in that direction. My problem is I can't make the plane change course. I rotate the course direction knob on the panel and the needle moves, but the plane does not change course. I obviously am missing something. 

Thanks

I once mixed up the heading knob with the compass deviation adjustment knob. That’s the only thing I can think of.  

Fixed it. My mistake. When I installed the latest update from Duckworth, I had first deleted the previous version from my Community file, then installed the latest version. But I had forgotten to unzip the download and had placed the zipped folder in my Community file instead. Removed it, unzipped it and installed the proper folder and everything is back to normal.
