All the commercial drones for agriculture we sell out are ready-to-fly commercial sprayer drones.
Before despatch, every uav duster drone is 100% tested and has to pass through a rigorous quality control test to confirm it meets the highest standards in performance and durability.
We manufacture commercial duster drones at first, and test them(Don`t worry, we test only with water, no pesticide).
The test usually include 4 times: no-load trial flight, semi-load trial flight, full-load trial flight, autonomous flight.
Only the qualified drones are entitled into our storehouse.
When customers confirmed their order, we will add the optional accessories and test them again, to ensure all functions work well.
