<p>A model toy includes an electric motor (1) which is powered by solar cells (3,4) which are located on the motor housing. The motor shaft (2) has a rigid connection with the model (7), whilst the motor housing is linked to the model by a rotary coupling. When activated, the rotary coupling engages an arm (8) which transmits a limited angular movement to a control element on the model. The coupling can be activated by the power from an additional solar cell, that is operated by a light beam from a torch.</p> |
