The German WWII warbirds have a simpler engine management, vs the Allies. In either case, I love 'em all.
For flight, the 109 is great. As noted, regarding the rudder. On the takeoff roll you'll need to give her a bit of rudder until the speed pics up. Other than that, the 109 is my favorite DCS WWII bird. (Until "Whistling Death" comes out). :-)
