Something strange happens with my joystick VKB Gladiator PRO and I had the same problem with my old Saitek X52 :
I have adjusted my sensitivities on pitch, roll and ruder.
During the first flight, my 109 (for example) is very sensitive on the pitch. It's like that my sensitivities configuration is not recognized by the game (70% for the pitch).
Ok...I stop the flight and decide to start a new one. During the second flight the plane is ok, sensitivities are ok, pitch is strong as I wanted.
I have always this issue on the first flight. The second, sensitivities work well as I configured them.
Anyone has the same problem ?
