The total amount of power for communications transmitted over channels susceptible to quality fluctuation is decreased to reduce interference with other communications and increase the system’s overall capacity. The method initially includes estimating an occupant classification. A control circuit is adapted to selectively provide additional volt*sec for at least one half of a cycle of the fixed frequency to the control winding. Therefore, the risk potential of the pedestrian M1 may be calculated at each point. Methods of fabricating the device, and the electrically conductive grid in particular, are also provided. The device may be used in a method for controlling and stabilizing a model helicopter, wherein the control comprises a self-learning function andor the control comprises a coupling of the tail controller to the swashplate controller andor the control comprises a stopping support function.
