A1
Abstract:
A small, radio-controlled helicopter with an internal-combustion engine with two opposed, simultaneous-ignition cylinders to reduce ignition vibrations applied to the helicopter body. Thus, when this small helicopter is equipped with apparatus for video recording or photography, it is possible to obtain clear picture images while preventing any unwanted movement of the camera. In addition, various other operations, such as the spreading of pharmaceuticals and the guiding of lead ropes, can be conducted stably.
