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 operable to control power to the aerodynamic thrust propulsion unit and to the traction drive propulsion unit to accelerate the vehicle; and both the first steering control input and the second steering control input are operable to control the direction of travel of the vehicle.
