depends on your application. I dont see what type of controller or interface to DJI controller they are using to control the pump motors? i am looking for granular type of spreader for seeds or insect application. for this sprayer attachment if you are in the US, youd have to comply with requirements for FAA Part 137 agriculture aerial operations.
Thanks so much! I am not in the US but in Europe outside of the EU, anyhow I suppose we have similar regulations.
I'll do some research or contact that manufacturer to find out more about how the unit / the pumps are being controlled.
Will let you know over here!
