Great article. I never looked at those professional drones and did not realize that they could carry a heavy payload like that. Hopefully they can develop and deploy the proper radar. I don`t see using spotters being very efficient. I loose vlos with my wifes drone 500 feet away when i look down at the controller briefly. Takes me a minute to find it when I look back up and I know where it was when I looked down. Kind of scary scenerio about the drone crashing with a load of fentanyl.
