Hi, there seems to be something wrong with ground friction on my AFS 2 setup. When I start a flight at an airport, I can't get the aircraft moving even with full throttle as if it were stuck to the ground. I thought I may had set the parking brake or wheel brake, but that was not the case. Furthermore, when I touched down a beechcraft baron with around 90 knots, it came to a stop after a ground roll of around 50 feet even without using the wheel brakes!?! According to the barons performance data it should have a ground roll after landing of around 1400 feet. So that makes me think there's something wrong with with ground friction on my setup. Any idea what's causing this? Thanks and best regards
