In 1983, Yamaha Motor Company received a request to develop an unmanned helicopter for crop dusting purposes from the Ministry of Agriculture, Forestry and Fishery of Japan. 
That began initial research and development efforts that led to the completion of the Industrial-use Unmanned Helicopter “R-50” in 1987. Whilst research and development efforts in the field of industrial-use unmanned helicopters was being carried out around the world, the Yamaha R-50 with its payload of 20 kg was the first practical-use unmanned helicopter for crop dusting.
