A non-flying land based training or testing vehicle with helicopter style main controls and capable of transporting at least one human operator. A preferred embodiment includes a chassis; ground contacting wheels supporting the chassis; a power-plant for driving a wheel and propelling the vehicle; at least one seat for the operator. The controls simulating helicopter controls are within reach of the operator and operatively connected with a computer and electric/hydraulic mechanisms (for example only) to provide similar effects as helicopter controls when manipulated. Such controls include a hand manipulable cyclic (joystick) providing an X-axis output for steering vehicle heading and a Y-axis output for determining forward or reverse travel; a lever style hand operated collective applying various loads to the power-plant to simulate changes in main-rotor blade pitch; and a grip for power-plant RPM manual manipulation by the operator for learning or practicing the maintenance of RPM under changing loads associated with various positions of the collective. Also included is a pair of foot pedals for making the rear wheels steer more than or less than the front wheels in a four wheel steering embodiment, and for simulating tail-rotor blade pitch or anti-torque control of a helicopter.

1. A land vehicle capable of transporting a human and useful in helicopter flight training, said vehicle comprising:a chassis; a plurality of wheels supporting the chassis; a power-plant supported by the chassis and operatively connected to means for rotating at least one of the wheels for propelling the vehicle; at least one seat for supporting at least one human to be transported by the vehicle; controls mounted on the vehicle and at least in part positioned accessible by a human in the seat for operating the vehicle, said controls comprising: a hand operable joystick operatively connected to means for controlling left and right steering angles of front wheels and frear wheels of the plurality of wheels responsive to hand inputs to the joystick, the joystick for simulating, at least to a degree, a cyclic control of a helicopter; a pair of foot operable pedals operatively connected to means for controlling left and right steering angles of the rear wheels of the plurality of wheels responsive to foot inputs to the foot pedals, the foot pedals for simulating, at least to a degree, rear rotor-blade pitch control of a helicopter; a hand operable collective lever manually movable and operatively connected to means responsive to movement of the collective lever for manipulating operating RPM of said power-plant, whereby various simulated loads resulting in power-plant RPM changes are applied to the power-plant responsive to movement of the collective lever for simulating, at least to a degree, adjustments in main rotor blade pitch of a helicopter; a hand operable throttle control manually movable and operatively connected to means for manipulating operating RPM of said power-plant, whereby said hand operable throttle control can be used to compensate for RPM manipulations caused by movement of said collective lever.
