I have an advantage that I live on top of a mountain about 1400 ft looking down at a canyon in Southern California . Most of my friends live down from me. We are surrounded by avocado and fruit and flower orchards so I feel safe flying around. The friend that lives above me, live close enough that I usually don’t lose connection. If I do , he usually hand launches me back into the air. The down side is RTH will bring you back to the spot you landed when making the delivery. As far as load, I don’t know. I’ve delivered small things that fit in case. I’ve had no performance issues. I ask my recipients to stand infront of the camera before I take off. When I get a thumbs up, I know it’s safe to take off. I live in the hills so it’s easier to send a drone to a friends house than driving. As the crow fly they aren’t that far, by car they are. Mostly I do it for the challenge to see if it’s doable. It blows my neighbors minds. They quickly learn to appreciate the drone and the pilot, especially when they gets little treats. I can’t pretty confidently say that I’m the first in my area to make a drone delivery to someone. As silly as it is, I get a kick out of it. One day it will become routine.
