• Model railroads for example, have a high degree of real-world features but this has not been transferred to other types of model tracks (courses).
• All of these tracks lack a high degree of realism in the models' handling characteristics such as scale acceleration, skidding (tire traction), braking, inching, reversing and more.
• many model tracks lack true scale realism during acceleration and braking of the model.

Acceleration, braking, adherence, suspension and tire traction (grip) are not adapted to the scales of model cars. This means that there is no realistic connection between full scale cars and model cars.

• the control unit 6 includes at least one transmitter 89 that sends control information to at least one receiver 36 with a reliable power supply from an accumulator in order to keep radio interference from occurring (that for example may occur from a power supply via dangling cords).
• the transmitter's antenna 91 may be connected with a conduit 92 to a layer of metal foil 93, for example aluminum foil or similar, placed in the lower course section 11.
• the metal foil 93 consists of net or similar. This design allows for keeping a constant distance between the transmitter and the receiver. The design also allows for transmitter signal output to be greatly minimized in comparison to known types of radio- controlled vehicles.
• Fig. 2 is shown in a cross-section how characteristics on the surface of the topside 10 of the upper course section 8 may be simulated.
• the simulation of characteristics on the surface of the topside 10 may be achieved by different surfaces on the topside of the lower course section that are provided with different characteristics, structures and smoothness (profiles). Different characteristics, profiles and smoothness on the surface of the lower course section will directly affect the conditions for propelling the drive unit and the model because the guide wheel's 34 diameter is relatively small.
• This design allows for the different characteristics of the different course sections to be realistically imitated. If the upper course section's surface (to its appearance) consists of a driving lane 17, the surface of the topside of the lower course section, on which the drive unit is operated, consists of a smooth surface.
• the surface of the topside of the lower course section may consist of a roughened surface. If the upper course section's surface to its appearance consists of gravel, that is to say where the car is "out of race", the surface of the topside of the lower course section is then made of a profiled surface that makes it very difficult or even impossible for the further travel.
• Embodiment Example that Includes a Device for Adjustment of the Rear Wheel's Road Grip and a Skid Indicator
• the present invention seeks to mimic true to scale the traction that a racing car such as a Fl-car has in reality. This means that the traction that exists during cornering for a full-scale Fl-car needs to be adapted (adjusted) to the desired scale level.
• Fig. 11A and 1 IB show an example of the device (design) with which tire traction according to scale for the model's rear tires 24 and 25 may be adjusted.
• An adjustment function for tire traction may for example be achieved by the model including at least one pivot wheel 94, which essentially bears the weight of the model's rear chassis 95.
• the pivot wheel 94 includes a bearing such as a miniature ball bearing. The bearing allows for the pivot wheel 94 to achieve a very low rolling friction.
• the rear wheels 24 and 25 bear only a minor part of the weight from the model's rear chassis 95.
• the rear wheels 24 and 25 bear only a miniscule fraction of the weight from the model's rear chassis 95.
• the relative distribution between the weight that the pivot wheel 94 bears and the rear wheels 24 and 25 bear may be adjusted via an adjustment device 96.
• the adjustment device 96 in the exemplifying embodiment shown in Fig. 10A and 10B consists of at least one double-tongued plate spring 97, alternatively at least one single-tongued plate spring, which in its one end 98 is attached to the vehicle's chassis and in its other end 99 is attached to, and holds up, the wheel axle 100 with the rear wheels 24 and 25.
• the wheel axle's 100 vertical position may be adjusted by the adjustment of the plate spring's 97 position in the vertical direction.
• the adjustment of the plate spring's 97 position may for example be achieved with the aid of an adjustment screw 101 or other for the purpose suitable adjustment device.
• Minimal tire traction consists of the guide wheel's (pivot wheel's) rolling friction, when the rear wheels do not come into contact with the underlying surface.
• each respective model's 3 value of tire traction may be calibrated in some form of test jig 102.
• test jig 102 One example of a conceivable test jig 102 is shown in Fig. 12. The degree of the slope's tangent value coincides with full-scale tire traction divided by the model's scale (for example 1 :43).
• the model 3 includes an indicator 104 which indicates (shows) if the model has been driven faster than the scale speed allows in a curve or another type of turn.
• Fig. 13 shows an exemplifying embodiment of the present indicator 104.
• the indicator consists of an indicator part 105 which is articulated and pivotally arranged around a fulcrum (axle) 106. Turning of the indicator part 105 occurs around an essentially vertical fulcrum placed in the vehicle's axial center line.
• the indicator part 105 includes at least one first part 107 of a material that attracts a magnet. To the first part 107 is attached at least one material layer 108, of a material that is preferably not attracted by a magnet.
• the design further includes at least one first magnetic body 109 and at least one second magnetic body 110 which are attached to the model's chassis on each side of the vehicle's longitudinal center line.
• the non-magnetic material 108 in part 107 trails along the course when the skid indicator 104 is used. If too high a speed is reached according to scale in a curve, the model's rear wheels will more easily release their grip against the surface of the course's topside than the trailing segment with accompanying angle displacement between the model 3 and the indicator part's material layer 108. When the change in angle is sufficient enough, the magnetic thinner section of part 107 locks against one of the magnetic bodies 109 and 1 10. The protruding section of indicator part 105 lies still in the indicated position until the time when a reset of the indicator 104 occurs. A reset of the indicator may for example occur when the model 3 is driven into a depot where the indicator is reset. Fig.
• the depot figures 1 15 lift/fixate the model's rear chassis by wedging.
• the control disc's powerful magnet 119 attracts the wider rear section of indicator part 107 to its neutral position and a reset of the indicator 104.
• the function and mechanics of the control disc 1 16 are made so that the magnet 119 has an increased distance to the underside 14 during the time of the lift of the model's rear chassis.
• the indicator's sensitivity may even be calibrated on a special disc with gradients and coupling points for the model.

• the present system has a single drive point, which replaces the differential technique.
• authentic engine sounds may be added in both stationary and driving modes.
• the present invention can indicate if the scale speed in curves has been exceeded. Tenth, this indication (fake accident) can be restored in a depot of a movable figure by hidden controls, while other functions such as timing can also be accomplished in the unseen plane.
• the driver's head in the models can lean proportionately to the radius of curves and the driver's head movement can also be controlled remotely when the model is stationary. Twelfth, small changes, one to two degrees negative slope, in the course's curves can easily illustrate a course exposed to different weather types, such as rain.
