Abstract: A vehicle having a first configuration for road use and a second configuration for air use, comprises road wheels; a first steering control input, such as a steering wheel, for directional control of road wheels when in contact with the ground; a traction drive propulsion unit for driving road wheels when in contact with the ground, for example an electric motor connected to each driven wheel; a traction drive power control input, such as a throttle pedal; a second steering control input, such as rudder pedals, for operation of control surfaces for the aerodynamic directional control of the vehicle; an aerodynamic thrust propulsion unit for driving the vehicle through the air, such as a motor connected to a propeller mounted on the vehicle; and a thrust power control input, such as a throttle lever; and optionally a road wheel brake control input, such as a brake pedal; wherein, when the vehicle is in the second configuration and the wheels are in contact with the ground, the thrust power control input is ope
