Just did an other flight tonight, same problem with autopilot only during initial climb and until 10000/15000ft. First when engaged PA after takeoff, nose diving and aircraft descent to -500ft/min. Just after nose up with a rate of 4000ft/min. So impossible to accelerate to 250kts. When engaging HT to try to stop climb and accelerate, aircraft refuse to nose down, still climbing and crossing 10.000 ft at the speed of 200kts. I switch off autopilot, level off, accelerate to 270tks and re-engage PA with IAS mode. At this time is becoming good with the PA until the end of flight.
Without GPS, community folder empty except only using GSX and some files link to navigraph. Pitch switch and PA activation use via joystick shortcuts.
