I had Phenom 1.3 installed in FSX. Flew fine at first, then developed a problem during taxi and TO roll, landing. With more speed, the problem became worse. Mostly a strong pitch to the right, then the yaw. Like the left or right wings were developing random lift at anything over about 20 knots. The problem mostly went away when airborne.
I thought FSX was just getting too old and I have too many add-ons. Time to try P3D v3 Pro, which is excellent so far.
My favorite bizjet seemed to be ok, but then started developing the same pitch/yaw problems on taxi. At first, it feels like you just ran over a small animal in the taxiway. Then, it becomes more pronounced. Very slow speeds are fine. TO roll immediately starts to make wild yaw and pitch that can't be corrected.
I'm purposely keeping my P3D install clean as a whistle, but did want the Phenom and my Duke Turbine. The Phenom 300 is the only aircraft that behaves this way. The trusty Duke and stock planes fly fine so far, but I do miss the Phenom.
Anyone else experience this? Thanks.
