[JeanBR]

Hello Guys, i have a 3DOF Sim and Assetto Corsa working there. My simulator can move 500mm up/down but this function can not work in my Sim. Lateral and Long forces works fine..but not vertical... I already add this force but nothing happens. Im looking for a solution by last 10 days and i cant to find nothing. Anybody could you help me?

Thanks guys!
