I recently rediscovered a freeware Piper Cherokee Warrior II I'd installed in FSX about a year ago, and decided to fly it today from KPSP to KSLC. I was very happy with its performance because it "felt" very similar to one of the Piper Cherokee Warriors I trained in, and it behaved accordingly. Unfortunately it has a 2 degree bank to the right that I can't correct. Ground taxiing is a bit bothersome because the airplane insists on veering to starboard with even a little throttle power. Opposite rudder counters the yaw, but not the roll/bank.When AP is activated she flies straight ahead and on heading, but not "true"; she still has that 2 degree bank, and if I look out of my port side I can see that the port aileron is slightly deflected downward, and my attitude indicator shows the same 2 degree bank. Is there a setting in its aircraft.cfg I can tweak to correct this? The airplane's file name is Warrior_II.zip, and I believe downloaded it from the Flightsim.com website. Some advice on this would be appreciated; she flies better than the payware Cherokee Warrior I have, and I'd like to make her one of my "regular-use" planes to tool around in.
