grape farms in Hungary, where conventional "main rotor and tail rotor" layout helicopters would damage or up-root the vine-stocks with their powerful airflow. Hungarian Kamov operators claim that coaxial rotors of the Ka-26 creates an airflow which allows pesticides to settle underneath, rather than on top of, the leaves, this means a much more effective distribution of pesticides, as most pests and parasites do not live on the top side of foliage. Additionally, the coaxial vortex system is symmetrical, allowing the distribution of the pesticide to be more uniform. On 30 June 2020, Moldovan police and prosecutors closed down an illegal factory producing unlicensed copies of the Ka-26. The factory had a production line with ten air frames in various stages of completion that were intended for sale to clients in former Soviet countries.
