Radio controlled surfboard with robotic rider controlled by two-string roto-wing

a radio controlled steerable self-propelled surfboard toy capable of moving on water comprised of:

• a posed robotic rider with a light upper body;
• a motorized self propelled surfboard having a hull with sufficient buoyancy to keep the vehicle afloat on water, and having a general longitudinal axis, said surfboard having an upper surface said upper surface supporting said robotic rider and an under surface;
• a keelson molded to said under surface;
• a heat sink fitted into said keelson capable of transferring heat from the hull interior area to the outside surroundings;
• a variable speed motor enclosed in said hull;
• a power source operatively connected to the motor;
• a control means operatively connected to the power source and motor for continuously and differentially varying, at the option of the operator, the levels of power supplied from the power source to the motor;
• a steering system which combines rudder movements turning in sync with the movements of the robotic rider's upper and lower body to shift the weight of the rider from one side of the surfboard to the other side of the surfboard by means of a two string roto-wing.
