I found lots (!) of good stuff at this site: http://www.douglasdc3.com/ It's not terribly well organized, but these folks are SERIOUS enthusiasts. I remember downloading a set of sounds for (I think) FS2K. The quality and volume levels were a little mixed; it sounded like someone just hung a microphone in the cockpit. Andy -- Andrew J.

My experience is that this works for directional control only at low speed. Slamming your foot down on one brake during a takeoff roll is not usually advisable. :) > Even without propwash, differential power should help the plane turn > as well, shouldn't it? True, but again, this isn't an option during takeoff. I think it's probably best to leave the mapping there for the moment. Prop wash isn't very far off, and most users are going to expect the rudder pedals to turn the nose. But I agree in principle -- the default mappings should match the controls that you have in the actual aircraft. > This is now all in the appropriate places in the CVS repositories; I > renamed harrier-set.xml to harrier-yasim-set.xml and dc3-set.xml to > dc3-yasim-set.xml for consistency, so > > fgfs --aircraft=dc3 > > should work Have I misunderstood something? In my build, --aircraft=dc3 doesn't work; I need to use dc3-yasim to match the name of the -set.xml file. Is there any reason for tagging the YASim planes specially when there is no overlap between the simulators? No big deal, just extra keys to type. > (I get a ground loop even when I'm stationary; oh well). Indeed. I failed to regression test a last minute change. The DC-3 has propellers that are both counter rotating and variable speed -- I'd never tried both together, so of course it didn't work. The right side propeller governor was seeking in the wrong direction (to lower RPMs).

This is now all in the appropriate places in the CVS repositories; I renamed harrier-set.xml to harrier-yasim-set.xml and dc3-set.xml to dc3-yasim-set.xml for consistency, so fgfs --aircraft=dc3 should work (I get a ground loop even when I'm stationary; oh well).
