PROBLEM TO BE SOLVED: To solve the problem of the difficulty to understand the functions of a control circuit for a vehicle that uses a crawler to be controlled by radio and to manufacture a sprocket wheel in addition to the control circuit.SOLUTION: In a control circuit, a base and an anode of a transistor and an antenna are connected, and a cathode and an emitter of the transistor are formed into a common terminal. A sprocket wheel is manufactured in a regular square when seen in rotational axis direction.SELECTED DRAWING: Figure 6 |
