Been working on the steering and the brakes in the Beech G58 Baron.
In the system.cfg file
[BRAKES]
parking_brake = 1 ;
auto_brakes = 0 ;
toe_brakes_scale = 0.50 ;
differential_braking_scale = 0.38 ;
In the flight_model.cfg

min_available_steering_angle_pct = 0.1 ; 0.2
max_speed_full_steering_castering = 9 ; 20
