Dear sir, I want to a build drone with 5kg lifting capacity along with 3nozzle spraying system,so please help these type of drones are available at you or advice to me for hardware configuration have to buy, & is it possible drones are control by Android Mobile? please help and suggest to me
Hi malli1040,
Building such a spraying drone will be a lot of trial and error and you really need to know about Drones if you want to start making this project.
We have a system made by a china company build for this purpose, the Agricultural Plant Protector Hexacopter w/ Sprayer will be an out of the box solution.
It does have an AutoPilot app if needed.
